So I'm now permanently running my computer with the CPU @ 4ghz[250x16] (1.52V), NB-CPU @ 2750mhz[250x11] (1.372V). I noticed I needed my NB voltage to be 1.26, as 1.25 would get no boot. Temps are 40C CPU@idle and 44-47C NB@idle.
By switching my NB-CPU multi from 11 to 12, I would get 3000mhz for my NB, but it required me to bump up my voltages significantly. I needed a stunning 1.5V for NB-CPU and 1.45V for NB. There was no change in CPU temps and NB temps went up about 4-5C(52C idle). Though my temps are fine, do you guys not recommend using such a high amount of voltage for permanent usage?

Just curious, but if the NB voltage has nothing to do with overclocking the NB frequency, how come I need it at 1.45V to cold boot a 3ghz NB OC? Anything lower and I get no boot. Same goes for a 2750mhz NB OC, I need it at 1.26V to get a cold boot otherwise 1.25V or lower gets no boot. Is there really no correlation or is it all in my head? Edited by Kokin - 2/21/10 at 12:51am
