840 MHz CPU?

post #1 of 9
Thread Starter 
Hey everyone. I have a question. I decided to overclock my CPU and decided i would download CPU-Z to get an idea of how fast my CPU was actually running before and after it. before the overclock Cpu-z said the core speed was @ 3.2 GHz. Okay, good. So i overclocked it to 3.39 GHz. Im still on stock cooling so i dont want to go crazy. I booted back into windows it said my core speed is 840 MHz..? Im confused and a little scared now. My BIOS says im still at the 3.39 GHz. Any thoughts guys?

That's just Cool and Quiet underclocking and undervolting your CPU while idling. It will go right back to normal when you run something.

You can disable it if you want while you OC, but after you are done you should but it back on as it saves a lot of power.

In addition to disabling Cool N Quiet in BIOS, also disable C1E support. It will throttle your CPU speed as well.
