Asus’ Z87-PRO motherboard reviewed

Haswell is finally upon us, and so are droves of new motherboards designed for it. For PC enthusiasts, the most interesting ones are based on the Z87 Express platform. The Z87 is the full-fat implementation of Intel’s latest chipset silicon. It offers six Serial ATA 6Gbps ports and six USB 3.0 ports alongside all the usual connectivity.

In addition to handling platform I/O, the Z87 unlocks a couple of processor-specific features. CPUs connected to the platform can split their 16-lane PCI Express 3.0 links into a pair of x8 connections for multi-GPU graphics configs or into an x8/x4/x8 setup for Thunderbolt. The Z87 also unlocks all of Haswell’s tweaking dials, allowing overclockers to push the processor to its limits—or just unlock a bit of “free” headroom with a decent aftermarket cooler.

There are dozens of Z87 motherboards selling online right now, each with a different mix of features and functionality. Over the coming weeks, we’ll try to cover some of the most interesting Haswell motherboards on the market.We’re kicking things off with a detailed look at the Asus Z87-PRO.

Asus has introduced a new black-and-gold color scheme with its 8-series motherboards. The aesthetic is a departure from the blue accents that have dominated the industry of late. The gold is supposed to convey a premium feel, and the anodized metal heatsinks definitely fit the part. However, the plastic ports and slots have more of a beige tone, which cheapens the look a little. I can’t look at the Z87-PRO without picturing a 1978 Firebird Trans Am with gold rims and faded beige upholstery.

While scoping the board from this angle, one of the first things that jumps out is the conspicuous lack of PCI slots. The PRO is PCIe-only, and it has dual x16 slots to take advantage of the chipset’s multi-GPU support. There’s also a third PCIe x16 slot at the bottom of the stack. This slot offers a maximum of four lanes of PCIe 2.0 connectivity via the platform hub. Those lanes are shared with the board’s four PCIe x1 slots.

Haswell’s LGA1150 socket lies north of the slot stack. Despite the processor’s new integrated VRM, the power circuitry surrounding the socket looks similar to what you’ll find on Ivy Bridge boards. This additional circuitry is all digital, of course.

Asus straps a pair of heatsinks to the Z87-PRO’s 12-phase CPU power solution. These ornately machined hunks of metal flank the socket boundaries on two sides. Fortunately, they’re short enough to steer clear of most aftermarket CPU coolers.

To provide a better sense of clearances, we’ve measured the distance between the socket and several on-board landmarks. We’ve also measured the heights of the inner and outer peaks of the heatsinks.

With the full ATX landscape at its disposal, the Z87-PRO does a good job of keeping the socket region relatively clear of obstructions. The DIMM slots are relatively close to the socket, but that’s true for all recent Intel boards. Be careful when combining wider aftermarket coolers with taller memory modules.

The Z87-PRO’s Serial ATA ports line the edge of the board. All eight support 6Gbps speeds, but only the six to the left are tied to the Intel platform hub. The two on the right stem from an auxiliary ASMedia controller.

The ASMedia chip lacks fancy features, but the Z87 has a handful of storage-related goodies. It supports RAID arrays and SSD caching, for example. Intel has also added a new feature called Dynamic Storage Accelerator. This addition purportedly improves I/O performance “by dynamically adjusting system power management policies.”

In addition to its six SATA 6Gbps ports, the Z87 has six USB 3.0 ports. On the Asus board, two of those ports are sent directly to the rear cluster, while two more power an internal header for front-panel connectivity. One of the remaining ports is routed through an ASMedia hub that shares the bandwidth among four more jacks at the rear. The Z87’s final USB 3.0 port appears to be untapped.

Even with some potential left on the table, the Z87-PRO is hardly hurting for SuperSpeed ports. The four to the left are routed through the ASMedia hub, while the other two are linked directly to the chipset. This arrangement makes sense; the ports coming from the Z87 sit under the Gigabit Ethernet jack, which is also powered by an Intel chip.

Display and audio outputs abound in the rear cluster. The Z87-PRO uses an updated Realtek audio codec dubbed the ALC1150. On top of that, Asus adds a layer of DTS software that offers two key features. The first is DTS Interactive, which allows multichannel digital audio streams to be encoded on the fly. Without this capability, multichannel game audio would be limited to analog output. The second perk is DTS UltraPC II, which offers surround-sound virtualization for stereo devices.

With an 802.11n Wi-Fi adapter complementing its Gigabit Ethernet controller, the Z87-PRO is primed to connect to just about any network. The wireless card is a dual-band affair paired with an understated antenna on a 31″ leash. The Qualcomm Atheros module that supplies the Wi-Fi link also supports Bluetooth 4.0.

Like the integrated audio, the on-board networking comes with extra software. Asus’ AI Suite Windows utility includes a bunch of networking-specific widgets, including support for DLNA streaming, remote desktop control, and file transfers for connected mobile devices. It also features a configuration wizard for client and access-point modes. Asus has become a bigger player in the networking business, and its growing expertise in that field is evident in the Z87-PRO.

Before we move on to a closer look at the Z87-PRO’s software and firmware interfaces, I have to take a moment to point out a couple of smaller hardware touches that no enthusiast board should be without.

The first is a removable port block for the front-panel connectors. Asus provides a block for the usual array of buttons and LEDs in addition to a second block for one of the internal USB 2.0 headers. These little accessories cost next to nothing to produce, and they can make system wiring much easier.

Asus has bundled port blocks with its motherboards for years, but this next feature is something new. Next to the POST code display is a tiny button labeled DirectKey. Hit it, and you’ll boot directly into the firmware interface without having to hit the Delete key. This might seem like a frivolous feature, but modern mobos boot into Windows 8 at warp speed, making it extremely difficult to enter the firmware manually. Now, about that firmware…

Firmware enhancements

Since the Sandy Bridge generation, Asus has arguably had the most enthusiast-friendly motherboard firmware in the business. The same basic design has been honed for Haswell, and plenty of little extras have been sprinkled on top. Take the UI, for example. Asus has maintained a familiar theme, but it’s changed the color scheme, fonts, and scaling. The end result looks cleaner and sharper to my eyes.

The EZ interface pictured above is targeted at newbies, and it’s traditionally been light on actual options. Asus has expanded its functionality for Haswell, adding XMP memory control and the ability to select pre-defined fan profiles.

The Shortcut button in the lower left corner has been carried over from Asus’ Ivy Bridge boards, but its contents are now customizable. Users can add shortcuts to any variable within the advanced interface. They can also populate an entire Favorites tab in the alternate UI.

Most of us modify only a fraction of the settings in modern mobo firmware. The mix of options is probably slightly different for each user, making the favorites tab a nice addition.

As one might expect, the advanced interface is teeming with tweaking and overclocking options. We’ve seen the vast majority of them before, but Asus has cooked up something new for CPU voltage adjustment. In the past, users have been limited to defining a static voltage or using an offset that boosts the CPU’s default by a specific amount. The offset mode is generally preferred because it allows the CPU voltage to drop when Turbo is disengaged.

Even with the CPU idling at its lowest clock speed, though, the offset mode applies extra voltage, raising power consumption and heat output unnecessarily. Asus’ new adaptive mode addresses this issue by applying an offset voltage only when Turbo multipliers are active. The CPU runs at its default voltage when idling.

Adaptive voltage control is pretty slick, but it’s not perfect. Haswell CPUs can request additional voltage under extremely heavy loads, and this is applied on top of the adaptive voltage set in the firmware. If your cooling solution can’t handle the extra voltage (typically around 100 mV, from what we’ve been told), throttling or worse could result.

Asus tells us that only stress tests like Prime95 will cause Haswell CPUs to demand extra voltage; even multithreaded rendering loads don’t hit the chip hard enough. The only way to stop this voltage grab is to set a static CPU voltage, Asus claims. Offset voltages are affected just like adaptive ones.

Another setting of note is MultiCore Enhancement, which has been used in the past to boost Turbo multipliers silently when unrelated system variables are changed. Asus promised it wouldn’t play tricks with Turbo this time around, and the Z87-PRO delivers on that pledge. We have seen some other Z87 boards resort to surreptitious overclocking, though. Stay tuned for their public shaming.

Like Asus’ previous UEFI iterations, the Z87-PRO’s firmware feels like it’s been designed for speedy navigation. The interface transitions are instantaneous, and the mouse and keyboard response are excellent. Most multipliers, clock speeds, voltages, and timings can be keyed in directly.

The advanced section of the firmware contains a couple of unique features we haven’t seen elsewhere. QuickNote allows text notes to be saved and modified within the firmware interface. Then there’s the Last Modified log, which keeps a running record of settings changes. The log can be accessed at any time and saved to a USB drive. An appended version is also displayed when you’re prompted to save changes upon exit. Pretty slick, no?

Speaking of slick, Asus continues to have the best firmware-based fan controls in the business. Users can choose between pre-baked profiles and manual tuning for each of the Z87-PRO’s five onboard headers. The fan controls are somewhat limited compared to what’s available in the new AI Suite III software for Windows, though. Let’s see what that app has to offer.

Fresh tweaking software

In recent years, Asus has put more emphasis on motherboard software. That effort continues with its 8-series family, which comes with the third generation of AI Suite. Like previous iterations of the tweaking utility, the latest revision is completely modular. Users can control which components are installed, although the overclocking, fan, and power controls are all lumped into the 4-Way Optimization module.

This all-in-one optimization tool combines automatic overclocking, power tuning, and fan control. Previous Asus software has supported automatic tuning in each of those categories, but this is the first time that a single routine takes them all into account at the same time. The one-button approach makes sense for newbies, and I suspect many enthusiasts will use it to establish a quick baseline from which to proceed with further tuning.

The 4-Way Optimizer can be tweaked in various ways. You can configure it to ignore certain categories, and there are secondary options within each one. For example, the auto-overclocker can be set to increase only the CPU multiplier, leaving the base clock steady. Unlike some automated overclocking software, AI Suite tests for stability automatically and reboots the system as needed.

AI Suite III is also well-equipped to handle manual tuning. All the most important overclocking knobs are there, including Turbo multipliers, CPU straps, and base clock controls. Adaptive and manual voltage adjustments are supported, and so are several power regulation options. While you’re fiddling with settings, you can keep tabs on frequencies, voltages, and temperatures using the monitoring pane at the bottom of the UI.

Apart from a brief polling delay when modules are launched, AI Suite III feels smooth and responsive. The interface is intuitive, though its high information density might be a little intimidating. Seasoned enthusiasts will probably prefer the denser layout. They’ll also appreciate the app’s sparing CPU utilization and tiny memory footprint.

The overclocking options are nice, but if I were building a PC based on the Z87-PRO, I’d install AI Suite III just for the fan speed controls. They’re that good.

First, there’s the profiling function. AI Suite can run connected fans through their full range of supported voltages to establish an accurate speed profile for each one. The app allows users to name the fans and define their positions inside the chassis. This positional information is then fed into the auto-tuning process along with each fan’s speed profile.

Once a fan has been profiled, you can drag multiple points along its temperature-based speed curve. Each fan also has an optional shut-off temperature that spins it down completely. To eliminate jarring transitions between fan speeds, there are separate sliders that control how quickly the RPMs ramp up and down in response to temperature changes.

If you don’t want to install AI Suite, you’re out of luck for Windows-based fan speed controls. However, you can still overclock using Asus’ lightweight TurboV Core software.

This stand-alone application offers a bare-bones interface for clock, multiplier, and voltage control. TurboV Core can’t manipulate the clock strap or variables related to the power circuitry, but it at least supports multiple profiles.


We could spend days exploring all the different ways one can overclock the Z87-PRO. Because our time is limited, we’ll focus on two approaches: the 4-Way Optimizer and old-school manual tuning.

The auto-optimizer took our water-cooled Core i7-4770K up to 4.7GHz within minutes. That speed was only applied to 1-2-core loads, though. 3-4-core loads were capped at 4.6GHz, and AI Tuner registered a CPU voltage of 1.392V. Our Corsair Vengeance Pro memory was also cranked up to 2400MHz—its maximum rated speed—and the DRAM timings were adjusted accordingly.

This machine-tuned config was stable under load, with only a hint of throttling under our combined CPU and graphics stress test. The automated tuner did blue-screen once in its search for the limits of our hardware, but it recovered gracefully.

You won’t earn any enthusiast cred with automatic overclocking, so we also pushed our system by tweaking the firmware manually. This time, we focused our efforts on the CPU exclusively. We also ignored the base clock and its associated strap. Our K-series Haswell CPU has access to high enough multipliers to cover all but the most extreme overclocking attempts.

Asus recommends that most firmware variables be left at their “auto” setting even when overclocking manually. The auto rules didn’t give our CPU enough voltage to go beyond 4.2GHz, though. Higher speeds required more juice, which we were happy to supply with a static voltage.

In the end, we got our 4770K up to 4.7GHz with quad-core loads, a smidgen better than the auto-tuner’s result. That frequency required 1.375V, and it was stable and throttle-free under load. We were also able to boot the system at 4.8GHz, but that speed required more voltage to avoid blue screens under load. Unfortunately, upping the voltage raised temperatures enough to invoke throttling even with our water cooler pumping at full speed.

Of course, your mileage may vary. You can read more about Haswell overclocking in this article.

Performance highlights

Comparative performance testing is a big part of what we do here at TR. However, it’s been a while since motherboards have had a substantial impact on system performance. These days, application and gaming performance tends to be bottlenecked by the CPU and GPU. Adding an SSD can improve overall system responsiveness, and faster memory can provide a boost in some scenarios, but that’s about it. Thanks to increased platform integration, even peripheral performance is largely consistent from one mobo model to the next.

There are rare exceptions to this general rule, and the only way to find them is to test motherboards exhaustively. We’ve done so with the Z87-PRO and comparable Haswell boards from Gigabyte and MSI. We also threw an Ivy Bridge-based Z77 board into the mix. We didn’t encounter any big surprises, though. The highlights of our findings are summarized below. Let’s look at those before diving into our full collection of benchmark results.

This is the part where I get to say I told you so. While we’re not looking at four-way ties in every test, the Z87 boards offer comparable application performance overall. The Z87-PRO is a tad sluggish in the 7-Zip compression test, but it’s less than 5% behind the fastest Haswell board.

The only contender to deviate consistently from the Z87 pack is our lone Z77 platform, which is running an older Ivy Bridge CPU and an Asus P8Z77-V motherboard. Haswell may not be a world-beater on the desktop, but it improves upon its predecessor in numerous ways.

Next, we’ll look at boot times, where we tend to see a little more separation than in our application benchmarks. Here, we tested the boards with and without their fast-boot options enabled.

The Z87-PRO isn’t the fastest-booting Haswell board we’ve tested, but it’s only 2.5 seconds off the lead. How much that’s worth will depend on how often you boot your PC.

I wouldn’t put much stock in such relatively small differences in boot time, but I would recommend playing with your firmware’s boot options. All the Z87 boards we’ve tested come with multiple settings to control how devices are detected at startup. You can easily shave a few seconds off your boot time without giving up anything important.

In the peripheral department, the Z87-PRO’s performance is largely equivalent to that of its peers. The following USB results come from TR RoboBench, which uses Windows’ multithreaded robocopy command to copy files to an SSD attached via a USB 3.0 docking station.

There are small gaps between the boards, but no single board comes out looking better than the others overall. At best, the fastest board is only 8% ahead of the slowest one, and the spread is generally much narrower than that. There’s enough run-to-run variance here that I wouldn’t worry about small performance deltas.

The Z87-PRO’s USB Boost mode does little to improve USB transfer rates. Asus’ boost software is limited in Windows 8, since the OS already offers native support for the UASP protocol employed by our docking station. The boost software does, however, offer a Turbo mode for non-UASP devices and enable UASP support in Windows 7.

Before moving on, we should point out an issue we ran into while testing the Z87-PRO’s USB performance. When our SSD was attached via the rear ports linked directly to the Z87 chipset, RoboBench and CrystalDiskMark hung occasionally during testing. The other external USB ports didn’t exhibit this issue, and neither did the ports accessible via the onboard header. Asus has replicated the problem, which is supposedly unique to our Thermaltake dock. (We haven’t encountered it with other USB devices we have in house.) We’re told Asus is trying to work with Thermaltake on a fix.

Update: Asus has supplied us with updated firmware for the Thermaltake dock’s ASMedia controller. The new revision resolves the issues we had on the Z87-PRO, though it’s unclear when or if the update will be made available to the general public. We’ve since tested a couple of other USB 3.0 devices in the Z87-PRO, and we didn’t encounter any problems with them.

Power consumption

There’s usually some variance in power consumption between different mobos, but there may be less with this generation due to Haswell’s on-chip voltage regulation. We measured power draw at the wall socket with our test system at idle, playing a 1080p YouTube video, and under a full load combining Cinebench rendering with the Unigine Valley demo.

The Z87-PRO is one of the most power-efficient mobos of the bunch. The top three boards are pretty close at idle and during YouTube playback. Somewhat surprisingly, our Ivy Bridge system consumes the least wattage under full load. The gap between it and the Z87-PRO is larger than the differences between all three Z87 mobos combined.

That’s it for our performance highlights. If you’ve seen enough test results, feel free to skip ahead to the conclusion for our final thoughts on the board. Otherwise, flip to the next page for the full motherboard specs, details on our system configuration, and all of our benchmark data.

Our testing methods

While we stuck with our trusty Corsair AX850 PSUs, H80 water cooler, and Force GT 120GB SSDs for this round of motherboard tests, we did swap in new graphics cards and memory.

Asus provided a pair of its GeForce GTX 680 DirectCU II 4GB graphics cards. These double-wide beasts have quiet coolers, beefy metal back plates, and more memory than your average GTX 680. You can grab one of them online for $570, and they include a free copy of Metro: Last Light.

We also upgraded our memory to Corsair’s latest Vengeance Pro modules. The DIMMs we used in our Haswell systems are rated for operation up to 2400MHz, and they look pretty slick. They’re so new that not even Newegg has ’em in stock.

Despite the fancy DIMMs, we stuck to 1600MHz memory speeds for most of our testing. Haswell may support higher memory frequencies, but anything above 1600MHz counts as overclocking. We did, of course, let Asus’ AI Suite auto-tuner take the DIMMs up to 2400MHz. They had no issues operating at that speed.

We used the following system configurations for testing.

Thanks to Intel, Corsair, Samsung, OCZ, and Asus for providing the hardware used in our test systems. We should also thank the motherboard makers for providing their products for review.

We used the following versions of our test applications:

Some further notes on our test methods:

  • All testing was conducted with motherboard power-saving options enabled. These features can sometimes lead to slightly slower performance, particularly in peripheral tests that don’t cause the CPU to kick into high gear. We’d rather get a sense of motherboard performance with real-world configurations, though; we’re not as interested in comparing contrived setups with popular features disabled.
  • DiRT Showdown was tested with ultra detail settings, 4X MSAA, and a 1920×1200 display resolution. We used Fraps to log a 60-second snippet of gameplay from the demo’s first race. To offset the fact that our gameplay sequence can’t be repeated exactly, we ran this test five times on each system.
  • Power consumption was measured at the wall socket for the complete system, sans monitor and speakers, using a Watts Up Pro power meter. Our video playback load used this 1080p YouTube trailer for the movie Looper. The full-load test combined AIDA64’s CPU stress test with the Unigine Valley DirectX 11 demo running in a 1280×720 window.
  • The Force GT 120GB SSD was used as the system drive for all tests. The Samsung 830 Series 256GB was connected as secondary storage to test Serial ATA and USB performance, the latter through a UASP-compatible Thermaltake BlacX 5G docking station. With RoboBench, we used the Samsung SSD as the source drive and the OCZ RevoDrive 3 X2 240GB as the destination for the read speed tests. Those roles were reversed for RoboBench’s write speed tests.
    The Samsung/OCZ tag team also powered our Ethernet transfer tests. The RevoDrive served as the source and destination on the host system, while the 830 Series SSD performed those duties on the remote machine. That remote rig was based on an Asus P8P67 Deluxe motherboard with an Intel 82579 Gigabit Ethernet controller. The two systems were connected via a single Cat 6 Ethernet cable.

    The Samsung and OCZ SSDs were secure-erased before each test that involved them. The Corsair drive was also wiped before we loaded our system image.

  • Analog audio signal quality was tested using RMAA’s “loopback” test, which pipes front-channel output through the board’s line input. We tested with the boards idling and with a combined load consisting of Cinebench’s multithreaded rendering test, the Unigine Valley demo, and a CrystalDiskMark 4KB random I/O test running on the Samsung SSD attached via USB 3.0.

The tests and methods we employ are usually publicly available and reproducible. All tests were run at least three times, and we reported the median of those results. If you have questions about our methods, hit our forums to talk with us about them.

Memory bandwidth

Since all our systems used Corsair DIMMs running at 1600MHz with identical timings, don’t expect meaningful differences in memory bandwidth.


Kraken JavaScript performance

We tested the latest Kraken release, version 1.1, in Chrome 27.

TrueCrypt disk encryption

TrueCrypt’s AES algorithm benefits from acceleration via Intel’s AES-NI instructions, which are supported by our Ivy Bridge and Haswell CPUs. We’ve also included results for another algorithm, Twofish, that isn’t accelerated via dedicated instructions.

7-Zip file compression and decompression

The figures below were extracted from 7-Zip’s built-in benchmark.

Video encoding

x264 video encoding

We’ve devised a new x264 test, which involves one of the latest builds of the encoder with AVX2 support. To test, we encoded a one-minute, 1080p .m2ts video using the following options:

–profile high –preset medium –crf 18 –video-filter resize:1280,720 –force-cfr

The source video was obtained from a repository of stock videos on this website. We used the Samsung Earth from Above clip.


DiRT Showdown

We busted out our Inside the second methods to testing gaming performance. While we aren’t showing all of our fancy latency graphs, we have included results for FPS and the 99th percentile frame time.

Boot time

Here, we measured the boot time after a full system shutdown. We used a stopwatch to time each test and stopped the clock when “Start” first appeared on the Windows 8 Start screen. Each board was tested with and without its fast-boot options enabled, and we took full advantage of Win8-specific features when in fast-boot mode.

The biggest takeaway from these results is the fact that Haswell is a little faster than Ivy Bridge overall. Our review of the Core i7-4770K tells that story in much more intricate detail.

Serial ATA performance


TR RoboBench

TR developer extraordinaire Bruno “morphine” Ferreira created RoboBench, a scripted file copy benchmark that relies on Windows’ built-in robocopy command to execute eight parallel file transfer threads. The movie file set contains eight similarly sized files totaling 5.6GB, while the mixed set has a diverse collection of 14,000 files that adds up to 10.6GB.

Although the SATA results show relative parity between the Z87 boards overall, note the differences in the performance of the auxiliary storage controllers. The third-party SATA ports are slower than those connected to the Intel chipset—often by substantial margins. We recommend sticking with the primary ports.

While testing the Z87-PRO’s SATA performance, we played around with Intel’s Dynamic Storage Accelerator a little. This feature needs to be enabled in the firmware and also in Intel’s RST software. Turning it on didn’t move the needle much in our tests, though. While SATA performance improved slightly in some runs, it didn’t in others, and the net gain was pretty minimal.

USB performance


TR RoboBench

In our USB tests, CrystalDiskMark teases out wider differences between the boards than RoboBench. However, the standings are shuffled for each and every test. I’m not convinced that random I/O performance is particularly important for USB devices, either. Our multithreaded file copy test is more indicative of the sorts of workloads faced by typical USB storage devices.

PCI Express performance


The Z87-PRO has a healthy lead in the random-read component of our PCIe performance testing, but it’s a little behind the curve in the other three tests.

Ethernet performance


TR RoboBench

Our networking results are very close overall. The Z87-PRO’s Intel NIC combines competitive transfer rates with low CPU utilization.

Analog audio signal quality

RightMark Audio Analyzer grades analog signal quality on a scale between “very poor” and “excellent.” We’ve translated those values to a numerical scale that starts at low of one and peaks at six. Higher values are better.

Our first set of results was gathered with the systems idling (apart from the RMAA app, of course). The second batch is based on tests conducted with the system under a combined CPU, GPU, and USB load.

RightMark Audio Analyzer audio quality at idle: 24-bit/192kHz
Frequency response Noise level Dynamic range THD THD + Noise IMD + Noise Stereo Crosstalk IMD at 10kHz Overall score
Asus P8Z77-V 6 4 4 5 4 5 6 5 5
Asus Z87-PRO 6 5 5 5 4 4 5 5 5
Gigabyte Z87X-UD3H 6 4 4 5 3 5 5 5 5
MSI Z87-GD65 Gaming 6 4 4 5 3 4 5 5 4
RightMark Audio Analyzer audio quality under load: 24-bit/192kHz
Frequency response Noise level Dynamic range THD THD + Noise IMD + Noise Stereo Crosstalk IMD at 10kHz Overall score
Asus P8Z77-V 6 4 4 5 4 5 6 5 5
Asus Z87-PRO 6 5 5 5 4 4 5 5 5
Gigabyte Z87X-UD3H 6 4 4 5 3 5 5 5 5
MSI Z87-GD65 Gaming 6 4 4 5 3 4 5 5 4

As far as RMAA is concerned, none of the boards compromise analog signal quality during our load test. That’s a good sign.

Regardless of whether the system is loaded or idling, the Z87-PRO’s scores are close to those of its peers. If you’re really concerned with audio quality, we recommend using a digital output or skipping the on-board solution in favor of a discrete sound card.


The Z87-PRO is a pretty sweet motherboard. Its $210 asking price is higher than the going rate for a lot of Z87 boards, but the PRO has enough extras to justify the premium. Take the integrated networking, for example. Gigabit Ethernet is handled by an Intel controller, the 802.11n Wi-Fi is a dual-band implementation, and Bluetooth 4.0 is thrown in for good measure. Then there’s the on-board audio, which offers premium perks like surround-sound virtualization and real-time multichannel encoding. Those features count for a lot on modern mobos.

Performance doesn’t count for quite as much, mostly because it’s largely consistent between the Z87 boards we’ve tested. The Z87-PRO has no problem keeping up with the rest of Haswell pack. It also has comparable power consumption and a similar number of peripheral ports. Odds are you’re not going to run out of SATA 6Gbps or USB 3.0 connectivity.

Asus really sets the Z87-PRO apart from its peers with firmware and software. While the UEFI hasn’t undergone sweeping changes, thoughtful little features have been added to the EZ and Advanced interfaces. The modification log is awesome, and I suspect the customizable favorites tab will be popular.

On the software side, Asus has completely revamped its AI Suite tweaking utility. Newbies should appreciate the improved auto-optimization routines, which were aggressive enough to nearly match the peak CPU speed we achieved with manual overclocking. AI Suite has robust support for manual overclocking, too, and its fan speed controls are especially impressive. The latest version of Fan Xpert is easily the best fan configuration tool around.

Despite its considerable appeal, the Z87-PRO isn’t flawless. The USB issue we encountered needs to be resolved, and the gold accents are definitely an acquired taste—or something you’ll forget about after stuffing the board into the dark confines of a case. It’s hard to find further fault, though.

We’re too early in our Haswell motherboard testing to say whether the Z87-PRO is our preferred Z87 board, but it’s definitely on our short list.

Update: The USB problem we encountered has been traced to the firmware on our Thermaltake dock. With that issue resolved, our only reservations about the Z87-PRO are cosmetic in nature.

  1. Keep the mobo reviews coming. I just might upgrade my Core 2 Duo E8400 one of these days. It just doesn’t do well with Photoshop and Autopano Giga when stitching large panoramas together. A while ago I had upgraded to a Phenom II 555 unlocked to 4 core but my mobo died and I could not find a current mobo that supported core unlocking.

    One of these should meet your requirement for a micro-ATX Z87 motherboard:

    I actually found a memory hole in one of the Asus software packages for my M5A99FX Pro 2.0. It would slowly start eating up memory over a week and I’d have like a 3GB program running, which I’d have to close and it would start all over again.

    Even if they tidied up the interface, the backend completely blows.

    One of the things I noticed while going through a few motherboards, is not all the fan PWM headers are controllable. This is something I thought should be standard that’s not. One of the ASrock boards I tried had two PWM header that were controllable, one that said it was, but wasn’t, and another that simply wasn’t even listed in the bios. Some of the headers also had different ‘levels’ of control too, which are ASrock terms instead of giving you actual variables to control. One header only had 5 speed settings, another 9. That’s really why I ended up sending that board back.

    With my current Asus board all four of my PWM headers for case fans operate on the same fan control, which seems… silly.

    Also the 60% limitation in the bios is also quite silly. Speedfan does a good job of overriding this, but then you lose the sexy power ramp control for setting logarithmic speeds.

    Fan control doesn’t look to be uniform across all makes and models, even from the same manufacturers, which is really disappointing. I agree about more thorough testing on the fan headers. Quite the odd ball was that ASrock Extreme 4 I believe it was, with a header that didn’t even use the PWM settings.

    A few words on the fan control options in BIOS.

    Asus was good in this department with their 6 and 7 series boards and still is, no doubt.
    However, what really annoys me is that they change the PWM duty cycle range in manual profile mode with almost every mainboard model.

    On some you can set it to a minimum of 0%, which means the fan is off with the right fan (some just spin on at 20% speeds), on others you are limited to 20% and on the Z87 Pro you are even limited to 40% minimum for the CPU fan. It gets even worse when you take a look at the case fan headers, where on some mainboards the minimum possible duty cycle in manual mode is 60%, which is really high.

    Yes, one can use the Asus Tool in Windows for better fine-tuning but not everyone runs Windows and not everyone wants to install this software with its numerous resident services.

    I had the chance to mess around with two models of the latest round of ASRock mainboards (Z87E-ITX and Z87 Extreme4) and I was surprised what ASRock has done here. In customize mode one can create a ramp-up curve based on 5 definition points, with a PWM range from 0 to 100% and not just for the CPU fan header(s) but for the chassis fan as well.
    The best of it all is that it requires absolutely no extra software, so it works whatever OS you are running.

    It may be hard to believe for some but imo ASRock has clearly overtaken Asus in this department.

    Suggestions for TR:
    1) Please take a look a closer look at those fan control settings when doing reviews (e.g. different PWM ranges, 3-pin fan support)

    2) It would be great to see a roundup of the fan control options offered by the big 4, maybe even Zotac and Intel. Iirc TR did something like this a long time ago when abit was still alive, it would be nice to see it again. Fan control options are very important and probably of more importance in daily use than 2 or 4 VRM-phases more or less or other marketing features most are never going to use anyway.

    Is there a version that’s the same, but less expensive and without Wifi? I find Wifi to be useless for my desktop enthusiast system which is less than spitting distance from my router. The one area of the house I need that sort of thing I have a switch with a wireless bridge built in.

    One small problem I noticed on Page 8: “As far as RMAA is concerned, our none of the boards compromise analogy signal quality during our load test.”

    The “our” is not needed there. Probably left over from when you started to say something else and switched thoughts at some point.

    • Visigoth

    So? Nobody’s forcing you to upgrade, little buddy. I don’t see why there needs to be any “fuss”. :-/

    Besides, it won’t be until Broadwell when Intel’s expected to give massive power savings on the new 14nm node, but that won’t happen until 2015 (2014 apparently will be a Haswell “refresh”, in other words, just a slight clock speed increase).

    I uninstalled the Asus suite as every time I rebooted I had to manually give about 6 separate components security clearance which is ridiculous. Hopefully they’ve sorted that with the new version.

    How about mentioning the bloat and startup programs Asus AI Suite brings with it? It adds executables like AsRoutineController.exe, AsSysCtrlService.exe, AlertHelper.exe, U3BoostSvr64.exe, PowerControlHelp.exe, EzUpdt.exe, EPUHelp.exe, TurboVHelp.exe, aaHMSvc.exe and atkexComSvc.exe was all I could find.

    I guess the AsusFanControlService.exe is truly needed to control the fans, so that one is just fine. The AI Suite II.exe is the program itself, but is not really needed to run all the time unless you want a quick access from the notification area.

    I really love the Fan Xpert program and use it to run the fans at inaudible speeds on both my PC and my [url=<]moms PC[/url<] but the startup bloat is just, uhm, UNPRECEDENTED.

    • willmore

    I think that sums it up nicely.

    • Chrispy_

    Yeah, the clearance is just one example – I rarely actually have problems with silly ornate heatsinks – they just irritate me with their unnecessary extravagance;

    A more efficient heatsink would be cheaper to produce, smaller, and more importantly the vast majority of PC cases don’t have windows, so it’s aesthetics (at some cost) for the contents of a dark, sealed box with no windows!

    Definitely #firstworldproblems though

    I’m going to be running under water…so I don’t even care about clearances as much as making sure my VRMs don’t melt. 🙂

    IF I had to buy today that’d be the board I’d get as well.

    I built mine on the Gryphon Z87. So far, so good.

    To be fair, if you’re going to dial back the acceptable mATX requirements to just what people need, they’d be better served by buying a pre-built box with a 3-3-3 warranty.

    I’m usually an ASUS guy too, but I’m actually more excited about Gigabyte’s integration of a non-Realtek audio codec on their Sniper M5. I’ve not been impressed by ASUS’ Realtek + Creative Software “SupremeFX” solution on their past boards (talk about picking the worst of both worlds), but preliminary reports suggest that the M5 might be the mATX gaming board to beat unless ASUS integrates one of their Xonar (C-Media) branded solutions in a sub $200 mATX board.

    • swiffer
    • 9 years ago

    I agree with your sentiments, the previous generation ([url=<]ASUS Z77-V PRO[/url<]) had much more refined VRM heatsinks.

    • swiffer
    • 9 years ago

    Compared to previous boards, these have smaller armies of capacitors surrounding the socket.

    Surprised that the media hasn’t given Intel a harder time over this release, at least in their desktop skus. What really meaningful benefit does Haswell and z87 offer to users of Sandy/Ivy platforms? 5-10% doesn’t warrant a look.

    If the rumors are true, Steamroller could be the way to go if its priced like current AMD platforms.

    Hmm. MId ’80s ThunderChicken coloring, enough Zs and 8s to make it stick, and I’ve got the latest fad. The Asus IROC-Z28 Pro motherboard, complete with free “gold” neck chain in every box.

    • MadManOriginal

    I’d like to see you guys test an Intel board for power consumption comparison. I chose an Intel board for my LGA1155 build because of the reputation for low power draw even though the only results I could find were from a user thread on some forum or another, not to mention it was prices decently. It idles at 42W at the wall with an i5 3570K, GTX 660, Intel 330 SSD, *and* 3 HDDs spun up, powered by a Seasonic G series 450W PSU. It’s not a huge difference in absolute terms (although accounting for the HDDs makes it even more impressive) but it still tells me that the Taiwanese manufacturers don’t do whatever Intel does in the power delivery section to really minimize power draw.

    Because asian marketing people who make these decisions think we want chintzy pointless rubbish instead of space for our CPU tower fans.

    I am a little surprised that Asus doesn’t have their ROG boards out yet. I was considering going to Haswell, so I was looking at Newegg and other sights, no ROG boards yet. I’m not sure I would buy one, just looking at the options. I’ll probably go with the Deluxe when I pull the trigger.

    • Waco
    • 9 years ago

    I have to agree.

    I don’t want “cool looking” heatsinks on my board. I want [i<]effective[/i<] heatsinks. Why is that so hard to accomplish?

    • smilingcrow
    • 9 years ago

    I think it allows much higher switching speeds (if that’s the correct term) which allows the Power Control Unit (ditto) to more aggressively and quickly transition between states which will save power.
    The upside for mobile seemingly outweighs the negative for desktop. Be interesting to see what the Xeon 2S and above chips use.

    • smilingcrow

    I’m looking forward to the Z87 Liberace Edition which has a pearl encrusted PCB.

    • vvas
    • 9 years ago

    I know most of your coverage is going to focus on Z87, but in one of the future articles, can you at least explain the differences between the various chipsets, when Intel is gracious enough to release some details? For example, if the only difference between H87 and Z87 is the OC, then obviously for those of us who are not interested in the K models there is little point in coughing up the extra dough for the latter…

    • ColeLT1
    • 9 years ago

    No Z87M Pro yet, but these are very close

    If you have no plans for a K chip:

    I also got mine yesterday, gota love newegg’s fast service.

    The Z68, 77, and 87 Pro have been my go-to for a handfull of PCs I have built, have not let me down yet. This one is for a friend, not worried about board, but hoping his chip is not a dud, unfortunately I put him off 2 months for haswell, oops.

    • kamikaziechameleon

    This is interesting but after looking at the blah OC ability of haswell and it rather boring performance gains for desktop I’m waiting for a true 8 core hyperthreaded CPU with quad channel memory. I’m waiting for the next true i7 line of processors.

    I kinda like the Harvest Gold accents. I look forward to boards with Tangerine or Avocado Green as well. They will go well with my 1972 Kenmore washer & dryer. 🙂

    The more of these Haswell reviews I see, the more I’m surprised that we’re just not seeing the large power saving claims that Intel made before the launch. None of those reviews were for laptops, they’re all desktop systems.

    This review made it pretty clear. What are those heatsinks around the CPU socket for? I though the VRMs were all supposed to be on chip. Well, they are, but the chip still needs to be fed a voltage dropped down from the 12V that the PSU provides. Then the chip will further drop it to the levels that the various parts need. Instead of removing a set of power conversion, it has added another layer.

    Traditionally, a system looks like:
    Wall plug (let’s say 120V AC) ->rectification/PFC->bulk DC->buck to 12V->off to MB->VRM->CPU
    Now we have:
    Wall plug (let’s say 120V AC) ->rectification/PFC->bulk DC->buck to 12V->off to MB->VRM->CPU’s VRM->CPU

    So, we go from two stages of power conversion to three–and one of them is on the CPU and makes it pay the thermal prices for any inefficiency.

    For desktops, that’s going to mask some degree of power efficiency increase from the new CPU/GPU design. Laptops will have it better as they only have:
    Battery->VRM->CPU, so they can shave off the ‘buck to 12V’ step and gain a little more efficiency over desktops.

    But, having the power conversion on the CPU die is still going to move heat dissipation from an area where it’s easy to remove to an area where it is harder to remove.

    Am I missing something here?

    As a Linux user, I love the idea of that DirectKey button. I’d have to think it’s going to be helpful for Windows people who are tuning their BIOS settings and doing memtest86+ runs before wanting to boot to the full OS where things might crash on an unverified memory system.

    • derFunkenstein
    • 9 years ago

    Are MSI and Gigabyte really calling their Z87 boards “Z77-GD65 Gaming” and “Z77X-UD3H”? It’s in your system setup table and it’s all over the graphs in the performance overview page. They have to be crazy if that’s the case, right?

    Nice review Geoff. I have one of these at home too, can’t wait to get it all built. Have not had time to build it yet because I found out my PS3 YLODed and I was tearing it apart instead, hoping a PSU swap will fix it :\

    • Chrispy_

    My [i<]first[/i<] gripe is of course the ornate, yet space-wastingly inefficient heatsink design - as per many motherboards.
