LGA771 based processors at 1066/1333/1600 bus speeds

The Intel Skulltrail platform consists of the Intel D5400XS motherboard that supports two LGA771 based processors at 1066/1333/1600 bus speeds, for up to 8-core processing. The Skulltrail configuration that we are looking at today consists of a pair of Core 2 Extreme QX9775 processors. The Intel D5400XS supports both Core 2 and Xeon LGA771 processors, so if you are worried about the budget alternate CPU's are available at various price points. The Intel D5400XS is basically a workstation board and as such uses the EATX format, so a larger chassis will be needed. The D5400XS uses up to four slots of FB-DIMM dual-channel memory at either DDR2 667MHz or 800MHz speeds. This might be the last time we see FB-DIMM's on the high-end enthusiast platforms as rumor has it that Intel might be going to DDR3 memory. Notice that the MCH is passive cooled, but the pair of NVIDIA nForce 100 chipsets and south bridge are actively cooled.
