Default Re: Overclocking Intel Core 2 Duo E6600 2.4GHz/1066

That is probably due to what people call vdroop.

The cpu voltage drops under load. I think its some sort of thermal or safety feature. It can be annoying while overclocking but its probably why our CPUs can take 1Ghz + overclocks 24\7 for years without failing.

Basically, you'll have to bump the voltage up more to compensate, and its up to you if you think its worth it. You'll get more heat (since the voltage will be higher at idle too), but you'll also get more overclocking head room. Since you're using a tuniq tower, you can probably go for it. Just watch your temps and use coretemp to monitor during testing. Most other programs don't report the correct temps.

I have my voltage set to 1.5v, which is pretty damned high, and under full load my CPU drops to around 1.44v. Thanks to the big ass cooler I'm using, the system has been rock solid for almost a year now. These chips are amazing.
