All performance tests run on the 875P-based motherboards utilized two 256MB Corsair TwinX PC3200 modules set to CAS 2/2T/5T/2T timings running in dual channel DDR400 mode. Any other performance-enhancing timings (like Command Rate or Bank Interleave) were enabled in 875P-based motherboards that contained such timings.
All performance tests run on the ABIT BH7 (845PE) motherboard utilized one 512MB Corsair XMS PC3200 module set to CAS 2/2T/5T/2T timings and running at 400MHz DDR. Optimal settings were loaded in the BH7 BIOS before memory timings were altered to CAS 2/2T/5T/2T and saved to CMOS.
Unfortunately we were unable to find a SiS 655 motherboard (and that includes the Gigabyte SINXP1394 used in our 800MHz FSB preview) that could run an 800MHz FSB CPU, with or without HT enabled. We were also unable to find an E7205, 850E, or SiS R658 motherboard that could run these same 800MHz FSB processors. There's a possibility that your motherboard vendor will release a BIOS update to enable 800MHz FSB support on these boards, but we've been told this is highly unlikely, so don't hold your breath. Therefore, users should not expect their current SiS 655, SiS R658, E7205, or 850E motherboard to run an official 800MHz FSB Pentium 4 processor.
