Overclocking of i7 920 do not touch the voltage

[Abbyss]

I've o / c my i7 without touching the voltage. 2.66ghz 3.06GHz past. I would also like the booster but first I want to know what temperature my processor can achieve full, 75, 80 ° C? In your opinion, how often to my i7 can go without touching the voltage. Why I do not want to change the voltage? For after this, it starts to heat up in earnest, and the life of my processor decreases anyway. My goal is to get close to 4ghz without touching the voltage.
My config:
i7 920 do
ASUS P6T
Corsair Modular 650w
G. Skill NQ Series - 6GB (3x 2 GB) - PC12800 (1600 Mhz) - CL9 - F3-12800CL9T
crossfire 5870
Turbo RAM Cooling: Arctic Cooling RC Turbo Module + 3 * ARCTIC COOLING Turbo RC
CPU Cooling: watercooling Corsair h50
cooled graphics cards: 2 * Artic Cooling Accelero Xtreme 5870
OS: Windows 7 Pro 64 bit

What is your current voltage? Already, the fixed at 1.25 in bios, do not let it Auto, the rest you Vqpi fixed at 1.25, to 1.25 Vioh also Vram to 1.60, and at least vich VPLL to 1.50 - 1.55 (unless you a higher minimum, you stare at a minimum), the ram at the lowest possible frequency, similar to the QPI link bandwidths etc. You do a OCCT test with these settings and if it takes you 1 hour increase of 5 BCLK What is your batch coeff and your processor?

So I doubt that it did not react to this. I turn to a 3.675Ghz 76 ° C under full OCCT I'll try to pass 3.7ghz with a voltage of 1.33V, no more after it starts to heat up and I still want to keep the CPU long enough I run a test on OCCT for 3.7ghz with a vcore 1.33V, we'll see if it would like to below 80 ° C Ps: if I get around the 3.7ghz I would be happy knowing that my goal was good but the 4ghz with a vcore to 1.33V it will be hard I think not?

Yes but hey it's the h50 Corsair watercooling lol baby is really starting kit. So for the 1.33V (vcore) 1:30 OCCT I'm a 79 ° C max in full for my i7 920 o / c to 3.7ghz, 3.696Ghz reality.I leave it like that I turn therefore to 2.66GHz 3.696ghz for a very good idle temperature. You think I was limited to 3.06GHz CPU for my crossfire 5870? because before I was at 2.66GHz and 3.06GHz and finally 3.7ghz.

ok ok I will win but good in perf anyway I'll do a benchmark test tonight Mafia 2, see if I won. And now I put a frigged i7 960 at which it has xD € 460.90, we see the price difference between 960 and 920. If I really want it be better that I invest in a real full water cooling kit but hey, must have money it's still cheaper than the i7 970 (859 €) or even i7 980X (€ 967.90).

[revolucioncg]

No here I just want to say that I liked, I did not have money to buy it xD but hey it is better now that my i7 975 no? it's a 3.33GHz quad core I think the 975 is not it? In any case if so, my pc has the mouth now, it's good o / c its a bit i7 Anyway glad to have reached 3.7ghz with 1.33V Vcore I could probably past 4ghz with a good thermal paste artic cooling and water cooling Corsair model over the H70. But there also must be good money.
