Gigabyte P35-DS3R BIOS
For some reason, the Gigabyte BIOS still requires you to hit Ctrl-F1 to unlock ALL of the options inside the tweaking menus, but overall did a good job of presenting options to the power user.
This poorly documented feature attempts to OC your PCIe bus for the graphics card.
The FSB on the Gigabyte P35-DS3R goes up to 700 MHz or 2800 MHz quad pumped. That should be plenty of head room for overclockers.
The BIOS does have a slightly annoying feature of blinking these red options on an off to indicate that they are high enough to possibly damage your hardware. It made taking screen shots pretty difficult.
The CPU voltages can go up to 2.0v here while the Asus BIOS limited us to 1.7v.
Here are all of the memory timings and settings you can adjust in the BIOS as well.
