Truly one of a kind

IF YOU'RE SHOPPING FOR AN enthusiast-oriented LGA775 motherboard, your choice of chipsets is dominated by offerings from Intel and Nvidia. There is a third option, though, and it comes from the unlikeliest of sources. You see, before it was acquired by AMD, ATI was working on a CrossFire Express 3200 chipset for Intel processors. That chipset survived the acquisition, and under new branding as the AMD RD600, it's made an appearance on DFI's LANParty UT ICFX3200-T2R/G motherboard.

The ICFX3200 is an event not just because it's the first—and thus far only—motherboard based on the RD600, but also because it's DFI's only high-end LANParty board for Core 2 processors. DFI has quickly established itself as a favorite among enthusiasts, and many have been waiting with great anticipation to see what motherboard whiz Oskar Wu can cook up for a Core 2-compatible LANParty.

Has DFI's combination of seemingly contradictory ingredients—an AMD chipset with an Intel socket—produced a motherboard with mouth-watering potential? Keep reading to find out.

Board specs
AMD's RD600 is easily the most interesting attribute of the ICFX3200, but the chipset itself is a little short on bells and whistles. The RD600 doesn't even have enough PCI Express lanes to supply CrossFire configurations with a full 16 lanes of bandwidth to each card. Instead, it must resort to a dual-x8 configuration—a trick Intel's 975X chipset has been pulling off for some time now.

As one might expect from a Core 2-compatible chipset, the RD600 supports quad-pumped front-side bus speeds up to 1066MHz and dual-channel DDR2 memory up to 800MHz. AMD is, of course, well known for the memory controllers it's integrated into Athlon 64 processors, but the RD600's memory controller is an ATI design.

Follow the four-lane PCI Express link from the RD600 down to the chipset's south bridge component and you'll find the SB600, a chip we've seen in everything from high-end CrossFire Express 3200 chipsets for Socket AM2 to AMD's latest 690G integrated graphics chipset for budget Micro ATX boards. The SB600 is a little light in the features department, sporting only four Serial ATA ports and lacking RAID 5. DFI makes up the difference by including an auxiliary storage controller from Promise that brings an additional four SATA ports to the table along with support for parity-powered RAID arrays. However, the Promise chip is tied to the PCI bus, so it will have to share limited bandwidth with other devices.

Fortunately, the Promise chip won't have to share bandwidth with the board's dual Gigabit Ethernet controllers. DFI calls upon a pair of Marvell chips to supply GigE connectivity, and both use PCI Express interfaces. In fact, the GigE chips hook directly into the RD600 north bridge, so network traffic won't even consume chipset interconnect bandwidth.

The rest of the LANParty's spec sheet fills out as one might expect, with VIA providing a Firewire chip and Realtek handling audio codec duties. You won't find a more ubiquitous tag team of onboard peripherals; if only VIA had a mascot, it could do a buddy movie with the Realtek crab.
