BIOS and Overclocking

The ABIT BIOS hasn't changed much at all. The Award 6 BIOS is used only this time ABIT has gone with a black and white colour style setup rather than the blue and red setup this BIOS is accustomed to. uGURU menu is the location for all of the overclocking features which the board supports.

Under uGURU menu you are greeted with the ABIT Overclocking which we are accustomed to. In order to gain access to the CPU Overclocking you need to set the CPU Operating Speed option to user defined. This will then give you control of the CPU.

CPU FSB can be adjusted from 133MHz to 600MHz in 1MHz increments and CPU Ratio can be adjusted on unlocked Extreme Edition and Core 2 Extreme processors. CPU voltage is adjustable from 1.3v to a max of 1.65v in 0.025v increments.

DDR2 Voltage is adjustable from 1.8v to 2.65v in 0.05v increments, certainly not the highest we have seen, but good enough. ABIT combines Northbridge and PCI-E voltage control into one setup and this can go from 1.5v to 2.0v in 0.01v increments - this is the highest we have seen for a Northbridge and PCI Express voltage setup.

PCI Express bus can also be adjusted from 100MHz to 200MHz in 1MHz increments. PCI Express is unstable when overclocked which means unless you are an experienced overclocker, it is best is to leave it at 100MHz for optimal stability.

With all these setting we managed to hit a massive FSB of 408MHz with the latest BIOS from ABIT installed. We did this with RAM at 1:1, Chipset/PCIE voltage at 1.9v, DDR-2 voltage at 2v and CPU voltage at 1.4v - it's a very impressive overclock from an Intel 975X based motherboard I must say (P965 is the better overclocker) and a sign that ABIT is back and they mean business like in the old times.
