Just been sprinkling some ket magical pixie dust on an old BIOS rev for the P5Q Pro that doesnt have that weird FSB enhancement option, and low and behold, it seems I can now do 1200MHz+ stable! Can't post any screenshots right now as I'm letting that system run OCCT v2a, over 20mins in stable so far. At least part of the key for 1200+ has been to set trfc to 42 and a performance level of 8. Will post screens when OCCT is finished.
