Mid-range potential?

AS THE LARGEST MOTHERBOARD manufacturer in the world, Asus has quite a bit of variety to its lineup. At one extreme, you have ultra-high-end boards with loads of auxiliary peripherals, onboard Wi-Fi, and all kinds of imaginative extras. At the other, there's a gaggle of budget-minded boards that skimp on extras, feature low-end chipsets, and generally don't offer many BIOS-level tweaking or overclocking options. The best enthusiast boards usually lie somewhere in between, combining decent chipsets with enough BIOS options for tweaking and overclocking, all without succumbing to unnecessary extras that would jack up the price.

Of course, there are plenty of mid-range motherboards with competitive feature sets and competent BIOSes. To really stand out from that crowd, middle-of-the-road boards need to go above and beyond the call of duty, and that usually means offering loads of overclocking potential.

We've had good luck overclocking Asus' mid-range motherboards in the past, and that gave us high hopes for the company's M2R32-MVP. With an AM2 socket, CrossFire Express 3200 chipset, overclocking-friendly BIOS, and street price hovering around $140, the M2R32-MVP has all the tools it needs to impress PC enthusiasts. But does it know how to use them? Read on to find out.

The M2R32-MVP is based on the familiar ATI CrossFire Express 3200 chipset, a chipset AMD is now trying to rebrand as the AMD 580X CrossFire. Rebranding doesn't change what's under the hood, though. You still get a north bridge chip with a whopping 40 lanes of PCI Express connectivity. Four of those lanes are used for chipset interconnect, leaving enough for a couple of full-bandwidth PCIe x16 slots with lanes to spare. A four-lane PCI Express interconnect only gives the chipset 2GB/s of bandwidth between its north and south bridge components, but with both graphics cards hanging off the north bridge, that's actually plenty.

At the south bridge, we find an SB600 chip that's starting to look a little out of date. The chip only offers four Serial ATA RAID ports. That should be more than enough for most folks, but it's two short of what's offered on competing chipsets. Chipset-level RAID 5 is missing, as well, although RAID 0, 1, and 0+1 arrays are supported.

The SB600 doesn't feature integrated Gigabit Ethernet, leaving it up to Asus to handle the M2R32-MVP's networking correctly. Unfortunately, they don't handle it so well. Instead of opting for a sensible PCI Express GigE chip, Asus cheaps out on a PCI chip from Marvell. That chip will have to compete for bandwidth with other PCI devices—an issue Asus could easily have avoided with a PCIe equivalent.
