Vcore voltages too high? 955 @ 3.4GHz

post #1 of 9
Thread Starter 
My CPU is running at 3.4GHz and the Vcore is at 1.42V, it was also at 1.42V at stock and everything set on auto, my idle temps are at about 28^C.

I was just wondering does anyone know if i could take my voltages down to like 1.375v would that cause an issue, or alternatively could i leave lower e.g liek 1.4v and clock to 3.6? my goal is 3.8, but i have heard by mobo is very poor at OCing.

As you can prob tell i am new to overclocking so any advice would be greatly appreciated.

If your 955 is a C3 stepping (you can find this on CPU-Z) it should be lower by a fair bit.
I am currently running 3.8Ghz at 1.4v on air cooling (CM 212+).
You should be able to cut the volts down a bit (1.325-1.35V) but this could be to do with your motherboard.
If you fill out your system specs in user CP, we will have a better idea what you are working with.

At 3.4ghz you should easily be able to get it down to 1.2v-1.3v, if your CPU isn't horrible. I wouldn't run the voltage that high on an MSI board, just to be safe.

my unlocked phenom is c3 stepping and it has a stock vcore of 1.42v same as yours with stock clock at 3.3ghz.

Your 955 vcore is probably normal.

A C3 chip should be able to run at 3.4GHz (and higher) with much less than that. I run mine at 3.8GHz with 1.35V. Oh and stock voltage for these chips is 1.3V...

Acceptable operating range is 0.875V to 1.5V, but it's always best to find the lowest voltage that you can get away with. And before people start getting all worked up about the voltage and saying that they have pushed more than 1.5V to their chips without problems... see my sig.

Drop voltages to 1.35V, overclock if needed between 1.35-1.4V,try not to go over.
post #9 of 9
drop the voltages and test on prime95

that's the best way to know if a lower voltage will cause stability issues
