3770k Clock Speed Changes Under Load

post #1 of 2
Thread Starter 
I have a 3770k with a Z77X-UD3H at 4.4Ghz/1.208v and it's stable in Prime95, but under load the cores will drop individually to as low as 3.5Ghz and back up again. The temps are under 80c and there's no blue screens/errors in Prime95. All C states are disabled and turbo is disabled also. What would be causing this?

Thanks.

Are you using real temp to monitor temps?

I had this issue once within the real temp settings you have to un check "Disable Turbo"

I hope this is the issue as this is what it was for me.

If not then I am not sure what the issue may be here..
