2500K OC questions.

post #1 of 4
Thread Starter 
Hey guys,

So i have been working on some OC-ing with my 2500k and i feel like i have hit a wall at 4.6Ghz. I was wondering if you guys have any suggestions towards my settings and how to push it further.

Mobo- p8p67 Rev3.0
Ram- corsair vengeance Cl 9
CPU - 2500k (h50 cooling)

Thanks thumb.gif

As long as your cooling can handle it then upping your CPU voltage and CPU current capability is the only way your going to do it. How much votage you want to give it depends on what you feel comfortable with.

My 2600K takes over 1.4v to be 100% stable @ 4.8Ghz. Some need more, some need less. Some wont do 4.8 with any voltage.

Theres people who recommend not going over 1.4v for 24/7 use. I would say this is sound advice. I choose to ignore it knowing the risks and being prepared for the consequences.

When stress testing make sure you are using the latest prime95 with the AVX plugin. Watch temps and make sure they arent going into the 80s. Your chip will throttle around 85 degrees before it does any damage but I personally would not want my temps to be getting that high for a 24/7 overclock.

Push more volts, I hit nearly 1.4 in windows for 4.8

Also disable c states and virtualization

yah, just push v-core up...im running at 1.36 to be stable at 4.6 for normal day use, but i had to hit around the 1.55 vcore mark to hit the 5.2ghz stable for bench marking which i only hit 72c on one core so i still had more room to crank even more out of it...but i agree that unless im doing a kamikaze benchmark run, im fine with the 4.6ghz at 1.36 vcore.strange that no matter what my vcore is it that my idle temps are still around 40c lol. and fyi, i am on water cooling.
but also, make sure you turn off spread spectrum and any auto overclocking things and turbo boost in the bios.
