680i 'safe mode' overclocking problem

[AWBbox]

Ok, so i've begun overclocking my system using the nforce 680i overclocking guide to teach me how. Whenever I reboot from making changes in BIOS, it stops to say that the computer is in safe mode, please reset CPU and FSB settings in CMOS. How do I make this work please someone?

System: Core 2 Duo E6600, 2G CellShock PC2-8000 (unlinked anyway), EVGA 680i (p23 beta bios)

The whole system is watercooled with (mostly) swiftech apex ultra bits.

Thanks.

Right, i've reset CMOS and reloaded the Beta2 P23 BIOS. Everything is back to normal sort of. I honestly don't know where I went wrong here. I really wanna OC this rig but I just don't know where to start now
