OC newbie

post #1 of 2
Thread Starter 
I have an I 875K and would like to get to about 4GHz. I have water.

I have used the EVGA K Boost feature that sets the mutiplier to 27 leaving the bclock at 133 for 3.6Ghz. When I look at CPUz, it still indicates 2.935 with a multiplier of 22 and the clock at 133. Why?

As far as CPU configuration, I have the following settings;

Vdroop=Y
cstate=N
Speedstep=N
CIE-N
HyperThreading=N (FSX does not do well with hyperthreading)

Concerning higher OC's, is it true that with a "K" processor, I can leave the clock alone and just use the multiplier for OC bumps? If this is the case, all the OC guides I have seen involve increasing clock speed.

Thanks,

Yea, you have an unlocked multiplier so you can essentially just move that, however I would advise against using automated software to do it.

Go into the BIOS and set the clocks multipliers and voltages manually.


As far as your issue, have you had the CPU under stress from something like Prime95 or Intel burn test? Because you probably have speed step active, that will clock you back down to stock when you aren't using the CPU to save energy and heat production.
