ASUS P5W64 WS Professional Motherboard Review :: BIOS and Overclocking

ASUS used a similar BIOS to that of their p6W-DH board, based upon the American Megatrends Incorporated BIOS (AMIBIOS). The BIOS chip is an 8Mb flash ROM, which is a change from the 4Mb BIOS chip from earlier boards. This BIOS is well-suited for workstation motherboards as many of the workstation motherboard manufacturers use it.

FSB frequency can be set from 100MHz to 500MHz in 1MHz increments the memory frequency can be set to DDR2-400/533/667/711/800/889/1067Mh when a CPU with the 1066MHz FSB is used. PCI Express can be set from 100MHz to 150MHz in 1MHz increments. Vmem can be set from 1.85V to 2.4V in 0.05V increments; Vcore can be set from 1.225V to 1.7V in 0.0125V increments. The MCH chipset voltage can be set from 1.5V to 1.8V in 0.1V increments.

ASUS has a tool called EZFlash in their BIOS to update their BIOS from a USB flash drive. Xbit Labs reports that they couldn't get the USB flash to work. The board on the test station shipped with the latest BIOS from ASUS and I did not need to flash it again. ASUS also has a feature called ASUS O.C. Profiles, where you can save overclocking profiles once you find a setting that works well. You can also use a USB flash drive to store profiles.

Overclocking on the board was not very successful. Using the ASUS AI NOS presets I was able to overclock the 3.8GHz CPU by 3% stably. Unfortunately, any attempt to overclock it using AI NOS above the first setting caused the system to either not boot or ended up with the standard default setting of 3.8 GHz. I've never seen an ASUS board not overclock to at least 10%, so I think it has to do a combination of the 3.8GHz CPU that we use in testing and the specific board on the test bench, as other sites have overclocked with this board well.
