Core i7/X58 Overclocking Thread

[mremulator]

Here you go, as promised It kept on going, 2h+ and then I finally stopped it. Temps were unchanged. Oh and, the load, it is 99.9% on all cores, but since priority was set to normal when I loaded CPUZ and went to take the screenshot it dropped off for a split second to 99.4% or whatever you see in the screenshot.

With good cooling this chip could do 4.4GHz or even 4.6GHz with HT on. On air 4.3GHz (another 100MHz) would be the absolute max I think with HT on. Still, considering that my room temp is 23C and that the temp around the computer is probably closer to 28C-29C this is very good. Finally an i7 940 worthy of its designation

My previous chip needed 1.46V to do 4GHz and temps were in mid to high 80s. Better cooling would allow me to drop the volts further as well for the same overclock. If I open the balcony door when Priming to drop the ambient to about 17C-18C I can drop the voltages for 4.2GHz to 1.38V.

What does everyone think about cooling this thing with the CoolIt Freezone Elite cooler? I do not want to go water because it is too much hassle for me, but I am thinking about FZE. Any opinions on it? What kind of temps can I expect?

dejanh, I have always been told that an overclock can't really be considered stable unless you can run prime (small FFTs) for 12 hours+ Can you??

Also, just out of interest what speed are you running your RAM @ now for that 4.2GHz clock?

Just sitting here waiting for the courier to turn up with i7 940 before I can see if 4.2GHz HT enabled if possible.

With regards to temps... don't be too sure about getting 4.3-4.6GHz with better cooling... I have a quad rad & GTZ block on a dedicated loop. My temps never exceeded 72c on my i7 920, however, I could not get past 4.0GHz prime (small FFTs) stable. 4.0GHz or below with HT & Turbo enabled is solid as a rock for me. But I want more!
