Trouble getting 5.2 Stable i7 2600k - Page 2

post #11 of 21
If you need 1.44Vcore for 4.8Ghz then you'll never get 5.2Ghz on 1.52Vcore. The higher overclock you want, the more exponential will your Vcore need to be to get stable.

Do u think raising my Cpu Current Capability past 100% would work? I can go to 140% but it would be red.

What is the make I want to take my vcores to 1.6v? I got 8hrs stable with 5.0ghz@1.52v using prime. Temp was 62c max with cooler midmay up. Cooler maxed out drops to 52c. ^^

Im not really sure what your asking, but if your asking if you should take your vcore to 1.6 to stabilize then NO.

For one that is a big jump, for two that is a **** ton of voltage and stress testing for hours under it would have the potential to be pretty bad for your chip IMHO. As others have said try dropping your pll voltage to like 1.5 and bring it up by quarters *1.525, 1.55, 1.575* until you can boot (you can fine tune afterwards) Then see if you can either maintain stability @ your current voltage, or even drop your volts a bit.

That said 1.52 even is enough to make me not want to go there (@ least not for a multi hour prime session or 24/7)

I suggest you do not go past 1.50V (this is also Intel's recommendation). Past it you risk breaking your chip's core components.

Yeah sorry. I was thinking what I wanted to say but finger did another. lol I read that some people in thread say dont go over 1.6v. I will try and drop my pll volt. Do u think I have to do anything esle in the Bios to help stable?

Why do you want go get this chip stable at 5.2 GHz? Are you planning to run it at this frequency longer time? Do you understand, that you might need voltages beyond the manufacturers specifications?

Maximal specified voltage for this chip is 1.52V at standard MB power settings. If you max out the settings, this voltage drops to something like 1.4 - 1.45V.

It depends how are you going to use the processor. If you will give it 50% average load for few hours a day and cool it well, I think you could go with up to 1.45V. If you are going to render videos 15h/day at 100% load, 1.35V is the maximum I personally would use.

"I want to get the processor stable at 5.2 GHz" is a wrong idea. You cannot do such thing.

What you can do is to see, what your processor does at the safe voltage. You may get to 4.6, 4.8, and if you are very lucky even 5.

Do not burn your CPU, please.
