Core i7/X58 Overclocking Thread

[Rammsteiner]

The jury is till out on the max mem voltage controversy.
INTEL officially told all the memory makers to keep the max v's to 1.65.
That said, there are quotes from INTEL engineers (well one anyway) that says that you can increase mem v as long as you do not exceed .5v over qpi.
So for example, if you run qpi at 1.35 you should be able to safely run mem v at 1.85v.
From what I can tell though - long term effects of any of this high voltage stuff is unknown.

That counts for a lot of things, in the end those max values are questionable too. Not like Ill go and try stuff

But yeah, in the end it's defined by Intel, the same compagny who isnt really happy with people OC'ing.

For example, I guess 1.4V QPI for 24/7 might be less harmfull then an i7 at stock running 95C 24/7, although IIRC that's safe. Oh well, I got the information I needed thus far, now I only have to wait for the parts

Heat is my problem (stock HSF) at the moment so don't have hard numbers but

19*211 with HT on will boot and do single threaded apps at 1.2v, 1.225v for untested stable (tested 1 minute because of heat)

Lowest stable vcore I've tried so far is 0.95v. 2.67Ghz. Runs 8 threads in prime, didn't crash.

Excellent! What are you using for a cooler?
