Foxconn's boards all use the AMI Megatends BIOS setup which AMI has now designed to look and function more like that of the Award BIOS. In the past AMI BIOS setups have been sluggish, restrictive in overclocking settings and hard to setup, now AMI has made a big push to get on the customers good side and the Foxconn BIOS is extremely user friendly with all the overclocking and tweaking you will need. To get access to the Overclocking section you need to access the Fox Central Control Unit Menu.

Overclocking our board was a pretty typical affair; thanks to the PCI and PCI Express clock controls we managed to lock them off to 100Mhz for PCI Express and 33MHz for the PCI bus. Doing this and keeping the RAM at 1:1 we managed to get 512MHz out of our board. We did this with both DDR2 and DDR3 memory and both hit a wall at 513MHz so we assume the board has a few issues going above this or the chipset itself (most likely the X38 chipset).
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.
