Is this CPU voltage right?

post #1 of 12
Thread Starter 
Hey folks

I have a Asus p8z68vle motherboard and a i5 2500k cpu

I had few troubles OCing this setup but i finally did it.

I now pushed it up to 4.5 and my CPU voltage is 1.215 ( i manually set it up to this level)

However when lurking around i see people having voltages @ 1.3s or 1.4s with my CPU @ 4.5 ghz

Am i doing something wrong? or since my PC does not crash is this an acceptable voltage?

My temps are 60-63 when gaming and i have a Zalman CNPS11x cooler as well.

How are you stress testing?

Either you aren't pushing the chip hard enough, or that is the best overclocking 2500k I've seen.

I am only playing games

Bad Company 2
Battlefield 3

are just 2 of them

I was using it at 4.0 with 1.180 voltage for 2 weeks and no problems

but now today i set it up to 4.5 with 1.215 again no problems.

Should i increase it to be safe?

Also the machine is running a bit more noise than the stock speeds.

is this normal too?

Yeah. Games aren't going to stress the CPU enough to matter. If you want to leave it that way, ok, but just know that you probably aren't stable.

What I would do is check out this link, download Prime95 and Intel Burn Test (IBT) and follow the guide to get stable.

That noise is probably coming from the fan trying to dissipate the heat caused by the increased voltage. No worries, but download RealTemp (the Sandy Bridge version) to make sure that your temps aren't too high.

I ran Prime95 for like 10 mins before I had to quit manually because i had to turn off the computer and go out

I also ran intel turbotest with MAXIMUM and no crashes...

Tonight when watching a movie i will let prime95 run for an hour

In Intelburn Test at 100% load the CPU went as high as 75 degrees.

What mode are you using in Prime95? Prime should run without any other applications opened (except CPU-Z and Real Temp). You want all the available memory to be used by Prime 95. I would let it run while you are sleeping. If it passes a 12 hour run, then you are probably good.

If you don't have that long, you can try a 50-cycle IBT run with maximum memory. Those temps seem kind of high for that voltage though...

That happens to me sometimes. Don't worry about it. If you are comfortable being at the voltage (which is very low) and you think you are stable, then enjoy!

AH cool thank you bro

Yeah when i get the message i thought it was an issue but hey it seems not

However i will give 1.235 a shot too and experience with it as well.

If nothing is different might go back to 1.215...

Thanks for your help by the way.

Your voltage may be set to 1.215 in your UEFI, but do CPU-Z/HWMonitor say the same thing under load in Windows?
