Don't know if this is due to that MOSFET problem but your temperatures are crazy high looking at that screenshot you posted up. It says 100C and around 60C per core!! I bet those temps are wrong though, because if it was really at 100C your CPU would be a melted mass of plastic :rolleyes:


I guess you never used coretemp before. 100C is the tjunction max limit. That's where the breakdown would occur if the cores got that hot. And BTW - 60C is nothing. I'm running my Q6600 at 3.0Ghz on the stock cooler, it reaches around 75C after a couple hours of prime95. No sweat.

Good job getting the Q6600 to 4 GHz. I myself wish I could be quite that brave, but at those high voltages, I always get the willies , as I only remember the good old days of the SNDS, the Sudden Northwood Death Syndrome. So, electromigration made me a whimp ;)
Still, most impressive!

^^Damn thats a sweet overclock!
Looking at your sig and seeing your temps I assume your using phase change cooling?
I've managed to get my Q6600 to 3.6 GHz on air with idle temp at 38c on the hottest core
and 68c on the hottest core at load under Prime95.

Thats some overclocking though mate :tomato:

Do all of you overclockers boot into XP to test stability? I am running Leopard on a GUID partition table so I cannot use XP other than in VMWare.

I want to overclock my Q6600 to around 3ghz on my DFI P965 mobo but am unsure about where to go to do stability testing. Any suggestions?

Kevin,

How did you get system profiler to show this extra info:

Any suggestions for how far to take the q6600 on stock cooling? I've run at 3ghz quite happily, but don't really have any reliable temp. monitors as yet..

Thanks for your help guys but I already am using command 3. I was referring to the processor features part and also the fact that my quad core does not display the processor name. Is that an SM Bios problem?

Thanks Kevin for that, but it made no difference. There used to be a fix called The "Colonels System Profiler Fix" but his website has long since disappeared! I remember using it and it showed the processor features, however, I am not sure which items it changed.

what speed are you actually getting? there's no way its actually 5.7GHZ, there's something wrong with your CPU reporting. show me a screenshot of your BIOS getting 5.7ghz and i'll beleive it.

Hagar: i keep my q6600 with stock cooling with a decent case (antec 900) at 3.2, it can boot at 3.3 and 3.4 but at 3.4 it starts to crash or fail some cputests until i increase my voltage quite a bit and also increase almost every voltage setting on my motherboard.

@Hagar, my Q6600 (G0) runs fine at 3.0 on the stock HSF. With the Arctic Freezer 7 Pro (one of the best value for money HSF's that exist) I can push it 3.4 at around the same temps.
