DFI has gone for the traditional Award BIOS setup which quite honestly has always been the best setup of all, though this may possibly change when EFI takes off. The Genie BIOS setup menu contains all the overclocking controls needed.

Being a DDR2 based board we didn't expect a huge FSB out of the X48 chipset due to limited DDR2 dividers, however we did manage to make a good fight out if it. We managed to get this board to 532MHz FSB without too much effort. We did raise the CPU core voltage just a tad, and the memory voltage was up at over 2.3v to get it stable. We also had to play with the ClockGEN voltage to get it all going nicely though the tests, but all was stable and I must say shows for a very tweakable board.
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 absolute 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.
