Running a P5K-DLX BIOS 311 and my "G0" Q6600 @ 413 x 9 (3.73ghz) I just tried to raise the FSB up 1 notch to 414 and the PC boots @ 3.33GHz . This makes no sense, I set the FSB back to 413 and all is fine. Is this a bug with the 311 BIOS? I know someone is going to say to flash to a newer BIOS, but 311 seems like the best all around BIOS to date. I would hate to have to flash to a newer BIOS.
