Need to know Voltages - i5 750 and Asus P7P55D Vanilla

[AmuseMe]

The computer that I built for my client about a month ago (Found here: http://www.hardwarecanucks.com/forum...ent-build.html) is back in my posession as he wanted the blue SilverStone 180s installed (pictures are coming to that thread very shortly ). He wanted me to overclock it, and even though I normally wouldn't OC a clients computer, he gave me the okay to do so. It is at 4GHz and has been OOCT stable, and Intel Burn Test Stable, and he has no complaints nor problems for the first month so far. However, when I first OCed it, I set the voltages rather high. Everything was still stable, and under OCCT the temps never went higher then 70C. He told me to just readjust the voltages when i put the fans in and this is where I am now.

Does anyone have their i5 750s at 4GHz (Actually I know many people do ) What are your voltages on everything? I just need to know a good ball park number. Or do I need not matter when everything has been good up until this point?

for the 4ghz mark most people get them with an average of 1.4V, but ive seen some board's get it at 1.375 to 1.45 depends on your hardware.

i can get mine runing at 4ghz with 1.4-1.44V but it gets too hot for my taster on the 212+ i have(over 75C and i rather keep it at under 70 for 24/7 use)

Currently its at 1.4. I've done 1.36 but that was only Intel Burn Test stable, and only with 20 runs on high mode. Im sure OCCT or Prime would bust it. How about your other voltages?

atm running it at 3.8

Blck : 200
multi : 19
ram : 1600mhz
cpu v : 1.3875v
IMC : 1.3v
ram : 1.5125(rated for 1.5)
PLL : 1.8625v
PCH : 1.1 (i think)
Max temps : 66C

seem's perty stable, some of them still need tweaking, but after 5 hours of prime95 and about 12h of Rosetta(folding) seem stable. debating uping the cooling to get it at 4ghz 24/7

Perfect! This is the stuff I am specifically looking for.

Thank you Patramix.

Well, I'm not at 4GHz, I'm running mine at 3.9GHz (21x186) on 1.245v, 1.22v VTT, 2x2GB 1860MHz CL8 Kingston HyperX Ram (1.65v), ASUS P7P55D PRO and get ~72C under maximum load after ~15 minutes of Prime (room temperature is about 22c). Cooler - Hyper Master 212+. At 4GHz CPU requires some more voltage and thus gets too hot.

I'll have to check my BIOS settings when I'm at home, but I'm running at 4GHz and in cpu-z when I check the other day it was 1.40 - 1.41 vcore. I'm running 200bclk at 20 multi. Temps can get up to 80-82C under heavy load these days; during the winter it was cooler though... The jump in volts going from 3.8 to 4.0 was pretty significant, for me at least.

same for me, witch is wy am running it at 3.8 as well.

with some tweaking i did manage to lower the voltage's a bit
v core to 1.325v
ram to 1.5
that's by enabling load-line calibration(had it off for some testing i did a while back)

temps on idle where lowered by 3-5c too, full load still around 65-68c

with my i5 750 and maximus iii formula, im at 20x200 with vcore 1.25ish prime stable.
lucky cpu?
