Whats up with this BIOS issue?

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:confused: . 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.

Odd.... I use 501 perfectly fine though :)

I had a similar problem around 452-454 Fsb. I set the Fsb in bios to these settings and it booted to 443 Fsb, then when I raised the Fsb to 456 it worked fine. This was with bios 501. I think I read another report in the P5K Deluxe thread that another person had the same issue. Might be a board glitch. Who knows.:confused:
Edit: Found it. Looks like the same fsb speed as you have. Click

Thank you so very much for your reply. I guess my issue is the same as that other guys, I set it to 415 and she boots @ 3.75GHz...... What a weird FSB hole. Thanks
