Abit IP35 Pro
After finally remembering to disable all the extra CPU Features in Advanced BIOS Features we finally unleashed the board's potential. Sure, you lose the extra CPU features, but it's necessary for the high FSBs. We managed to get the board all the way up to 495MHz FSB with a Core 2 Duo E6750 processor, but it wouldn't boot at 500MHz for anything. We've seen 500+ capable on this board but you need a really good CPU to get there.

We did manage a superb 485MHz FSB stable, which is one of the highest stable overclocks we've obtained, but it did require a bit longer to find the right voltages to make it happy. It's a touch of "DFI-syndrome" in that respect, where you can get quite frustrated narrowing down the various options finding a combination that works for your hardware. In all though, a fantastic result for the Abit IP35 Pro although we had wished to finally crack 500MHz FSB.

Quad-core overclocking was also very successful as we managed to get 400MHz FSB straight out of a 1333MHz quad-core CPU, however we suffered inadequate cooling from our Zalman CNPS9700 as the CPU shot straight to 83°C.

We also experienced a large Vdroop where our 1.40V applied voltage was read as just 1.34V in uGuru and that dropped to just 1.21V when the CPU was loaded. So, a classic overclocking dilemma presented itself: lower the voltage to drop the temps and the CPU will become unstable, but we can't upgrade the cooler since we have nothing more powerful. Instead of testing stability, we aimed for the highest possible and managed 465MHz that was able to boot into Windows with relative ease.
