And yes, VID is a factory stamp, because it managed to pass intels batteries of testing at a lower voltage for whatever reason.
Some boards/builds/programs will make it variate. But your processor has one somewhere. And so far from what I can tell, it DIRECTLY affects the processors performance.
Most will say that it doesnt, but they obviously cant read.
By all means, point me to someone whos low VID processor cant be OC'd due to the processor itself, and not the Mobo, or ram, or components! I've tested a few, and talked with others while they are testing, and so far, the lower the VID, the lower the heat, and the lower the power required to obtain a stable OC at whatever speed.
I have a 1.2625 and a 1.3000 G0 now, and the higher vid one acts just like you would expect. Its hotter, it needs more voltage, and it reaches the voltage vs. performance/speed threshold quicker.
(As in, when you OC the processor, you hit a point where the speed you get for the VCore cost is just to high. I can get 3.6 @ 1.38 VCore with my 1.2625 VID. The cores are cool. Thats an excellent value for VCore VS. SPeed! BUT... somewhere near that 3.6 a strange thing happened, but not unexpected, to get a prime stable 3.8... a mere 200 more Mhz, it now needs 1.51 volts. For a little more than that total raise, I obtained the 1200 Mhz extra for 3.6! Wow.)
And as expected, the high VID one reached that point quicker, needed 1.44ish to reach 3.6! So not only did it need the difference in value from VID's, it also need more on top of it because the voltage started higher to begin with, and it appears that the higher the voltage AS WELL AS speed and heat, makes you need more voltage! Its a neat little cycle.
Fun, fun! Cooler means you need less voltage to be stable at a certain speed, so if its hotter, I assume its the opposite effect! It appears to work with the tests I have done!
Blahblhablhababblebabble!
