Core i7/X58 Overclocking Thread

[dejanh]

cmon a screenshot of your load temps with the tool of your choice running 1 hour.

I'll get you the screenshot but it will have to be later as I have to go to work now But I'll try to get it to you tonight. If it is tool of my choice, I will use Arena chess test. I like that the best and it seems to simulate real-life workload the best, plus it loads all 8 threads at 99.9% constant. For now, I can say the temps get to about mid-80C (depending on how hot the ambient is, and I usually keep mine pretty warm for my tropical plants, about 23C).

As I thought, it looks like that extra multiplier does the trick at the same voltages.

dejanh... your Corsair RAM looks like it may perform better than mine, as mine will only do 1600MHz @ 8,8,8,24,1T and not 7,8,7,20,1T. I also have exactly the same mobo as you.

Also bearing in mind your observations... why are you not running 22x190 instead of 21x200??

Getting my i7 940 tomorrow.

I'm running 21x200MHz because I cannot run the memory at 1600MHz with 190MHz BCLK. It is either below or above. Running 1900MHz on the DRAM is not possible unless I really loosen the timings to like 9-9-9-24-2T and up the volts somewhat.

Also, I am not sure which observations you are refering to, but if I remember correctly rge and myself found that running a higher BCLK with a lower multiplier requires less volts than other way around...am I going back on myself here?

Those Corsair are a real letdown I must say.
My OCZ can go upto 1650Mhz @ 7-7-7-18 1T.
And so far I only managed to go up to 1850Mhz @ 8-8-8-18 1T, 1.64v and it seems like I stopped because of my uncore.

Not bad for 1333Mhz Ram

I was doing 1800MHz with the Dominators at 8-8-8-24-2T stable before (never tried to tighten the timings) so I'd say they are okay.
