DFI’s BIOS setup is based around the same BIOS they have always used for their Infinity range of boards with Overclocking Profile saving, so you can simply recall what setup you had and can tweak it even further. All of the overclocking features lie under the Genie BIOS setup menu.

Overclocking
Overclocking on this board was pretty good considering. The limiting factor was the CPU voltage which would tend to fluctuate under Windows when loaded up. If you set it too low it would under volt and cause system crashes, too high and thermal problems arose.
We did manage to hit a max speed of 502MHz on the FSB with all of the settings available to us. The best feature we found was the Boot-up Clock. This allowed the board to boot to the BIOS using a specified FSB speed that would allow posting, and then increase the FSB to its set limit; this would give it more of a chance to boot up when first turned on in the morning.
Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren’t able to tweak the motherboard to the maximum and find the highest possible FSB as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. “Burn-in” time might also come into play if you believe in that.
