Core i5-2500k Overclocking Issue - Please Help!

[topdogpenguin]

My Core i5-2500k is overclocked to 4.5ghz and has been for over a year now and my compute has always been very stable. However, I recently replaced my thermal compound on my cpu and I was doing a prime95 stress test when I noticed that before I start the test, coretemp reads my clock speed out at 4500mhz, but as soon as I start the stress test, the clock speed drops to 3600mhz. This is odd because it does this before the cpu has a chance to heat up, and under load the cpu will only read about 68 degrees on its hottest core, and I have a pretty beefy cooler. Also, when im gaming on the system, the clock speed doesnt seem to drop, it only happens when I stress test the system. 

 

Do you guys think this is just something to do with prime95? Or is my cpu throttling? 

 

Thanks

If there is an option like HPC (high performance computing) make sure it's enabled, otherwise it will throttle if it uses too much power. Not sure if it is even present on intel boards, this is just the case on AM3+.
