Hi guys. I have now got a Q6600 G0 and i have hit a snag. Went straight in and got it running at 3.2ghz (8x400) with a Vcore of 1.35v no problems. This morning i upped the voltage to 1.4v and went for 3.6Ghz (9x400). Surprisingly it booted straight into windows (XP). I started up core temp and TAT to check temps which were 22/20/22/24. Started up prime to test for stability and the pc locked up. Ok, not a problem, try more volts. Restarted the pc and went into the bios and set the voltage to 1.475v which is what others seem to be achieving 3.6ghz on. Save and reboot only to get stuck in an endless loop of restarts. Switched off and cleared the cmos (god i hate the positioning of the jumper on this board). Dropped to 3.4ghz (8x378) with the same voltage. Same story, endless restarts. Reset cmos again (Grrrrrrrrrr). Set to 3.2ghz (8x400) as i know this works but with the same 1.475v. Same again. Puzzled now???? I then dropped the voltage a notch at a time and it would'nt boot again until i got down to 1.375v. Something weird going on here as it appears that this cpu does'nt like voltage. I have been running prime all day at 3.2ghz (8x400) with 1.35v Vcore to find a stable base to work from. It has run now for over 12 hours and temps are 38/36/38/39 which seems damn good to me. Looks like i have found my stable base so where do i go from here? Does anybody have any ideas please? At the moment my 4300 is the higher clocker. The Q6600 G0 is a L726B053 if that's any help. The rest of my rig is in my siggy.
Should have said i suppose. That was one of the first things i did as it was on the 2.66 multiplier before with my 4300. Ram is set to the 2.0 multiplier now so it is clocked at 800mhz. I know it's good for at least 937mhz anyway.
