Overclocking issues (freq drops to and then returns)

post #1 of 3
Thread Starter 
Hi, im having alittle issue with my overclock. When ever i use prime to stress test it, some of the cores drop their frequency to 3.4GHz and then bump back up to 4.4GHz and it goes on and on. The test itsself has yet to fail.

Shows you exactly what im putting into the bios and what not and the pc actually starting up and then the freq droping. Thanks if you can help me!

The video was a lil blurry at times and it cut off the right side of the screen. However it looks to be that you have your c -states enabled. Disable the c1e/c6 options in your bios and you should see your overclock remain steady. Also you can go into your power options in the control panel in windows. Open up your power plan and then advance settings. Set the minimum cpu frequency to 100%.
This should keep your frequency more or less where you set your overclock.

You can google c-states. Pretty much it throttles your cpu down when your not using it. When your testing it, between que's you may see the frequency drop for a second or two depending on the program your using. Many people keep c-states enabled to reduce cpu wear/tear. If your cpu is stable, I say try and keep em.

There is an option in you're bios called APM, you need to disable this, this is what causes the CPU freq to fluctuate up and down continuously as you are experiencing, hope this sorts you out.
