Core i7/X58 Overclocking Thread

What are your timings for both 1600 and 1800?

8-8-8-24-2T (default timings, need to tighten still so may require a bit more volts than 1.65)

Very good response!

Thanks again for your input.

I'm going to continue to do more testing and once I get proper cooling I'll be able to start eliminating some factors from the stability equation (at least some heat!)

I'm still baffled by one thing though...turbo and when it shuts off. If I Prime and the temp hits 85C turbo shuts off but the CPU does not crash, but if I just run some application (like Vantage CPU test) and the temp goes to 85C the system hardlocks. But this is only on 23x180MHz, not 23x179MHz

Has anyone seen anthing about whether ASUS is going to be releasing any BIOS updates which will let us adjust the QPI and/or memory multipliers downwards? I think that it's holding my rig back significantly. I have 4.0Ghz rock stable at 1.36v with HT on but have to use a Bclk of 211 and a 19x multiplier to do it.

I would not hold my breath on this. Nobody is doing it, so I do not think Asus will either...maybe post it as a Feedback and Suggestion on Asus forums?

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!



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.

Dominators are 8-8-8-24-2T stock.
