BIOS and Overclocking

We have already covered the BIOS in our nForce 500 series review which this board participated in - therefore, rather than having you go to this page, here is a snip from that review:

Located under the Main BIOS menu is Genie BIOS Menu. This has all the clock options. FID can be changed under the main menu; you can adjust from 4x up to the maximum your CPU supports (in our case 10x).

CPU voltage ranges from 1.0v up to 1.60v in 0.025v increments. DRAM voltage goes from 1.8v up to 3.0v in 0.05v increments, the best we have seen for DDR-2 voltages. Chipset voltage ranges from 1.2v to 1.5v in 0.1v increments for the Northbridge, 1.5v to 1.8v for the Southbridge and 1.3v to 1.5v for the Hyper Transport voltages. FSB ranges from 200MHz up to 500MHz in 1MHz increments.

With these settings we managed to get 375MHz FSB with DRAM 2.2v and all other voltages set at stock. We did try a few extra voltage tweaks and we did get more speed but that resulted in a few too many random reboots. We use a 6x multiplier to give us 2.25GHz for overclock tests - quite an impressive FSB!
