BIOS Features
This is the initial view of the MIT (Motherboard Intelligent Tweaker) menu in the BIOS that allows for tweaking of options. Gigabyte still uses the hidden menus to access all the overclocking options, which you can “find” by hitting Ctrl-F1 at the main BIOS menu.
Here you can see that the CPU frequency can be boosted in single MHz increments all the way up to 400 MHz.
The PCI Express bus can be moved independently up to 150 Mhz.
CPU ratios are available to you as well: you can move all the Athlon 64 processors down in multipliers and the FX processor line allows you to move both directions. Here the Gigabyte board is showing us multipliers all the way up to 20x, but only in full increments, no halves here.
In what looks to be a similar idea to the Asus PEG option, Gigabyte has included a “Robust Graphics Booster” that as far I could tell, didn’t do anything. I set it at all three options and ran a couple of benchmarks, but couldn’t find any noticeable change in performance. I’m waiting for word back from Gigabyte on exactly what this does.
CPU voltages can be increased up to 1.75v, over the default 1.5v on this FX-53 processor.
Here you can increase the voltage to the core logic chipset (the nForce4) by up to 0.3v.
