2500k Overclock to 4.6ghz

post #1 of 12
Thread Starter 
Hello.
I've been overclocked to 4.5ghz with a vcore at 1.352. To me, this is pretty high for just 4.5ghz. Temperatures are idle at 30-32 and 45-55 on load.

Would I have to have an insane increase with voltage for 4.6ghz? I'm talking 1.4v.
Let me know.

This is the only vcore that i'm able to be stable. It's quite sad. Auto Vcore doesn't work 4.2ghz+ on my board.

don't worry, youll be fine taking that chip 1.4+ volts. Your H80 will have no problem with 1.4v
also are you reading your voltage from cpu-z or what you set in the bios?

From cpu-z. I just have a feeling that i have a bad chip, because i see people at 4.7ghz with 1.35-1.36vcore which is pretty good i guess.

It varies from chip to chip. There's a guy that has his at 5.0 GHz and only 1.340 V or something. There are also people at 1.450V at 4.7 GHz.
 

For what it's worth, I'm at 1.336V and 4.7 GHz and I can't even get 5.0 GHz without going crazy on voltage. 4.9 GHz was unstable for me at anything reasonable and 4.8 GHz just gave me too much heat.

 

Just set your CPU multiplier where you want, and run the voltages up in .010 increments until you're stable and then fine-tune things.

I feel ya. I have to run 1.48vcore in order to make 4.8ghz stable. Its up to your personal limit on vcore to how high of an overclock you want to go.

really needing a little extra voltage doesn't make it a bad chip, really depends on how high you can get it without letting it get to hot. Really just keep the temps under 84c while burn testing and make sure it can do a 24hr p95 then it should be good.

Yeah i'll probably play around with it. We'll see how it goes.
