CPU throttles back under full load

No matter what frequency I run it at, whenever it is 100% load it down-clocks back to 3.4ghz. After decreasing the load it goes back up to 4.5ghz.

What cpu? What Motherboard? Sounds like Cool n Quiet is enabled in the your bios. It will throttle back your cpu to maintain temp and noise settings.

Ah yes sorry, I have an i7-2600k with a MSi Z77A-G41 motherboard.

I have never heard of cool and quiet, I don't think my board has it. I've read that the G41 isn't a great overclocker at all but I can't even get 4.2ghz without throttling! What is up?

what are the temps at when it does this? What kind of cooling are you using?

Is there something called Speedstep in your bios? It's Intel's equivalent of Cool N Quiet. Other than that I don't know. It's not a cooling issue, so maybe a hardware problem.

Sorry, been away for a while, I haven't been able to find any cause for this. No Speedstep or Cool N Quiet. Is there any other explanation? It is certainly tolerable as it usually doesn't downclock during games but I am curious to what causes it.

The max temp for your processor is 72.6c. What happens is when any single core reaches from between the high 60's or higher is will throttle back to prevent reaching/exceeding that max temp. This is designed into the chip and the only way around it is to achieve better cooling. Maybe try water cooling with a large radiator.

I don't believe the max temp is 72.6C... I've seen others reach higher temperatures with stable overclocks, I don't believe temperatures are the case. From what I've managed to research you are talking about the maximum heat of the IHS, not the cores. Any other suggestions anybody?
