Decided to have a go at overclocking my q6600 earlier (go stepping vid 1.2750) disabled all the neccesary thermal and spread spectrum settings, set memory clock mode to unlinked and upped the fsb to give a frequency of 3ghz (vcore of 1.325) saved to cmos. on reboot i just get to the screen where it asks if you want to start windows normally or safe mode etc. thought it might have been a voltage problem so i rebooted and tried vcore on auto but got as far as the xp load bar screen before the pc froze. could this possibly be a bios issue as im still on ver p26 which is quite old now.
