All testing was done on a fresh install of Windows Vista Ultimate 64-bit. All benchmarks were completed on the desktop with no other software programs running. All of the modules were run in dual channel mode with a 120mm fan placed on top of them to keep them cool except for the Core i7 system that was run in triple channel. The EVGA GeForce 8800 GTS 512MB used NVIDIA ForceWare 169.28 video card drivers. The LGA 775 test system used the ASUS P5E3 motherboard using BIOS version 1404 and the LGA 1366 test system used the ASUS P6T Deluxe motherboard with BIOS v8004. The AMD Phenom testing was done on the MSI K9A2 Platinum motherboard with BIOS v1.5b5 installed along with ATI system driver version 8.50.
