with a dual core i don't believe the FSB Fine Tune makes any difference..with my quad (9650), i tried it both ways...still can post to boot...i haven't been successful yet to get a P95 off the ground..tried enabling and disabling, nada!...might need more Vcore...or...my memory timings could be to tight...Prime 95 is not important to me since i rarely or never use the full four cores at 100%....if i can run 3D benches and PCMark 2005 along with Wprime bench, i will be content.
