Cpu-nb?

post #1 of 7
Thread Starter 
How much voltage should I be using? Right now I'm running it at 2750MHz. For some P95 stability I just bumped it up to 1.35V, but I'm wondering, how much do I really need? 1.25V? 1.3? Auto?

And how much would the current 1.35V be affecting my load temps? Load is ~48 C at 3.89GHz with 1.4375V.

Edit: Just realized I posted this in the wrong section If a mod could please move that'd be great.

It actually varies from chip to chip. At 2750mhz cpu-nb you will need somewhere between 1.3-1.35v leaning more towards the 1.35mark, so i would say that you are fine. You can run it in lower voltage but the system wont be stable and you will get a lot of error 1001/1002 in Prime95. This means the system will crash during gaming and you will get crappy results while performing complex computations.
As for temps, lowering the cpu-nb voltage will only lower your cputemp by a few (1-2) degrees.

At 2750Mhz... you're about at the max of the C3 revision IMC overclocking.

Closer to 2900 MHz I would say.

Alright, cool. Just wanted to check to make sure I wasn't overvolting too badly.

I had 2800MHz stable before at around 1.3V. It's only at 2750 now because I changed from 200*19 to 250*15.5. I'm gonna try for higher later.
