I have been overclocking an i5-2500k and under load, the ratio drops from 44x to 40x or lower. I have disabled speedstep as well as c states. Any ideas?

Did you do anything with vdroop? What is your bclk? How did you OC - raise the cpu multiplier, or the turbo multiplier?
llc is at "level 2" in the asrock bios, second highest setting I assume it's 75%
bclk is 100
cpu ratio was raised, turbo is disabled
I really have no idea why the ratio would drop if turbo and speedstep are disabled =/ even if the voltage were dropping, wouldn't it just cause instability?
Sorry, should have been clearer- use coretemp to look at bclk while under stress. It could be dropping.
Else, the CPU might be throttling. What are your temps?
LOLOLOL
Make sure TURBO is enabled, you can't overclock without turbo.
If you want a static frequency, you can only turn off speedstep. But turbo has to stay on.
um I am pretty sure I turned off turbo and raised the multiplier before to oc.LOLOLOL

My asrock z68 extreme3 was doing this with my 2700k until i changed the Power Draw limit I believe in CPU voltage setting. It defaulted to 100 but i changed it to 200 after searching and seeing similar problems. I saw no more problems with overclocking after that.

The default limit was 150 on my board(z68 pro-3m) so I set it to 200 first and then to 300. Both times the ratio would stay at 44 for about a minute and then drop to 35.
Errr, I can. The multiplier is unlocked...
