Core i7/X58 Overclocking Thread

[Xello]

But isn't Intel's suggested limit for QPI/vtt 1.35V?

Yeah... I guess it's possible that everyone here running over that spec including myself will be shelling out for a new chip in a few months. I'm hoping not Also, there is Saaya's VTT graveyard thread which has some info on the first posts of rigs which have been running at certain settings, one of which is 1.45v. If i check that post one day and read that the cpu is bust, i'll reduce mine instantly and pray!

I have the Corsair Dominator XMS3 1.65V 3x2GB 1600MHz kit and I can easily get 1800MHz out of it without any voltage tweaks really. It runs 1800MHz just as it runs 1600MHz at 1.65V. Going to 1900MHz I have to up the voltage to about 1.68V - 1.7V, but that is it. Right now I am running them at 1.65V 1800MHz.

Cool, i've started with 1648mhz and 2 hour stable so i'll increase bclk 3 or 4 points and see what i can get before i increase V's. I assume they're still samsung IC's, they appear to overclock extremely well. If they can go to the 1800mhz~ mark that will make the final i7 OC alot better!

Is there a way to find out what your memory's stock timings are? The board has setting 1T for me this whole time and i didn't realize, i think it's meant to be 2T for stock, because under cpu-z SPD tab under the XMP-1600 profile it has 2T CR . All my sub-timings are on Auto in bios, i have 1.66v manually and 9-9-9-24 manually.

There's a 'performance' setting in bios where you can choose Standard, Turbo or Extreme, it's Turbo on default, is that something to do with memory sub-timings? Perhaps that's why i'm on 1T.

Anyway since it's setting 1T i was wondering if there might be any other timings it's tuning without my say-so, i really want them all @ stock while i find max clocks, i'll find timings later. CPU Tweaker is good for showing you all your timings in windows, but i don't know if the numbers i'm seeing are @ stock or not.
