Help me stabilize my OC ~5GHz

post #1 of 18
Thread Starter 

Hey guys, so I recently switched from AMD to intel and now I need some help stabilizing my overclock.

I am using the 2500k cooled with corsair H80 and Asus P8Z68-V as motherboard.
I used this video guide since I didn't know which bios settings to disable etc, for stability:


Now, I am not folding on this machine, I am only looking to getting the max/most stable overclock for gaming.
I can do 4.5Ghz on 1.250V but I think I have hit a wall after that, although temps seem fine.

I tried 4.8Ghz with 1.38v and 5Ghz with 1.40 but both failed on intel burn test, max temp was 75C when my PC froze.
So, any suggestions are welcome!

more vcore if you are freezing during IBT I would say 9 times out of 10

especially if you are freezing and not BSoD'ing, you are close... bump it up a notch or 2 and try then. You using LLC?

My i5-2500k needed more then 1.5vcore to get to 5GHz stable so you probably need to up it more. Max Safe vcore according to intel is 1.52v but i would stay below that if i where you.

5.0ghz at 1.4v would make that a near golden chip. Definitely need m0ar voltz.

What up Stuuut?

Can you post the settings that you have changed? From there we can see if you need to change something else.

Instead of guessing the voltages you need for 5GHz why don't you go up from your stable settings for 4.5GHz in small increments?

Hey Hambone hows it going??

Well Hambone is here now he helped me with my overclocking really awesome.
I did reach 5GHz the day after that but i didn't keep it the temps where too high and vcore was just over max safe voltage
So you need to be lucky with the chip you get.

LLC is on Extreme

Guys what about CPU Current Capability, should I leave it on 100% or increase it?

Yeah probably better, that's what I am trying to do.

LLC should be on second last can't remember what it is probably Very High and CPU Current Capability should be on 130% i believe.
Atleast thats what Hambone teached me
