lowest vcore for a c2d@3GHz

Jack Bauer · 10 Mar 2007 at 11:40

In an atempt to lower my load temps at 3 GHz Im dropping the voltage. This is working slowly however im a bit supprised. Im at 1.25 v at the moment and its orthos stable at least for short periods (Aint done a long test yet). Anyone else tryed this and if so how low will these go generally?

yeah i would be interested to find this out too, my e6700 is at 3ghz and 1.275 volts if i remember right, but would like to know just how low you an take the voltage and it remain stable

Well I left it at 1.25 and im upping fsb again as the temps are lower again, @ 3.15 GHz stable so far

again 10 min orthos tests just to crash it, not full stability tests

Each core will vary, for instance the last Opteron 144 i have can do 2.4Ghz on a measly 1.2v but had 144s before that could only manage for e.g 2.3GHz with 1.5v! and the steppings weren't far off. Currently have an E6600 that can do 3.2Ghz on 1.35v but had a previous E6600 that needed 1.45v for 3Ghz. Theres really no minimum voltage for a cpu, if you got a great core it'll usually be able to go a fair lower than others for the same speed.

ok crashed at 3.3 @ 1.24 v

dropped it to 3.15 GHz,

Not sure if it was a fsb or memory limit I hit as I aint tested it that high. Will leave it at this for a while and see what its like temp wise.

EDIT: for people intrested I found a particular point in or vcore that gave a large temp drop, was around 1.3v for me. Above and below this only changed the temps a little.

best i can manage is 1.300V at my 3.2Ghz overclock (E6600) although it dropped my temps from 65 under load to around 58, so a good decrease really.
