955 Max safe CPU-NB voltage?

post #1 of 33
Thread Starter 
Right now I have it at 1.450v, and it's not stable at 2900MHz. My temps are fine, is it safe to go higher?

No, that's the CPU voltage. I'm talking about the IMC (CPU-NB)

NO!!! AMD says CPU/NB voltage is 1.55v Max. AMD says CPU voltage for a 955 is 1.425v max. OCER says CPU voltage is 1.55v on air. I know my stuff.

Yes.... You can have the CPU-NB as high as the Vcore. But generally speaking the CPU-NB voltage should be lower. I would say 1.45V would be a good stopping point.

Thing is, I have my bus speed at 223MHz, so it's either 2676 or 2899 for the NB. (NB multipliers increase in 1x increments, rather than 0.5x on the CPU)

So do you think it would be better to run 4GHz/2.67GHz than 3.9GHz/2.9GHz?
