2500K OC help

post #1 of 5
Thread Starter 
I built this system for a friend and after following some of the OC guides I still cannot get it to OC. I really dont know what is going on. Please help!

System:
2500K
ASUS P8Z68-V/GEN3
2x4 GB gskill ripX cas 9
212+ with mx-4
rosewill hive 750W
win 7 x64 ultimate


These are the settings used, to no avail.

I dont know what is wrong with these settings, the system will boot but it is still at 3.3 ghz in cpuz. Also the CPU voltage in CPUz is high(about 1.35)? but in hw monitor it gives a different reading.

You have Intel Speed step, Turbo and C1E enabled. That'll change the speed according to workload.

Doesn't it go to 4.2 Ghz when you run prime95?

About the voltage ... I guess your stock VID is 1.33 V if it reads as 1.35 in CPU-Z. Of course this changes with vDrop and VDroop (but shouldn't vary a lot if you're using offset voltage from what I've heard )

That voltage is quite high for 4.3 BTW

EDIT:
The speed and voltage changing according to workload isn't a bad thing as it reduces heat and power consumption. On higher clocks it can mess with stability but @ 4.3 I'd leave it enabled.

You should also increase the power limits when overclocking.
Check the Sandy stable club for a wealth of information about overclocking wink.gif

Looking at munaim1's settings could help. Looks like those were on a P8 board as well:

DISCLAIMER: NEVER copy-paste settings from other people. Use them as a guideline at most. His settings are for 5.1 Ghz which is in a completely different league then 4.2 Ghz in terms of overclocking.
Go up in increments and test thoroughly.

It did not increase when running prime 95, and I have read that VID is not the same as core voltage. Anyone with more insight into this exact mobo would be super helpful.

I did not copy paste settings, The settings above are modified from 2 cables settings. The cpu current cpability is at 120% not 140 and my offset is at .02V as opposed to .04V.

I'm sorry, I didn't say you blatantly copied settings. Sorry if it came across like that. It was more a warning in general.

Wel, you could always just disable intel turbo, up the power limits and see what it does. To get rid of the downclocking disable C1E and Intel Speedstep.
Power limits are: Short Duration power limit and Long duration Power limit. Increase them to their max values. Leave Short/Long duration maintained on Auto.


VID is the stock voltage for your CPU according to Intel's tests. If you use Offset mode it takes your VID as the baseline and adds the voltage you have set in the BIOS to your chip's VID when at full speed.

Thank you, I will try to play with these settings later today as I have classes in a bit.
