Core i7/X58 Overclocking Thread

[roller11]

Thanks for the pic, that makes it clear.

best overclock I have been able to hit so far with my C0, have not had much time to work on it better.

welcome to XS jake, good clock bro

Roller11:On the pots i have, it have holes drilled in the base=)

Does anybody here now anything about Xeon W3520 batch:3849A773?

[PytonOrm]

Holy just Priming at 4600mhz at 1,44v on a core i7 extreme 975 and this is on air with Noctua cooler for Lga1366

good cpu indeed... Week 45

[Jakethesnake011]

That is a nice clock, let see how much higher you can go

Yes, I've seen that design detail. Seems like the reason for the holes is to increase surface area.

4.41 Ghz at 1.34 vcore/1.34 qpi/vtt for 24/7, linpack 5gb 20 run, and prime 8+hrs stable.

rge, thats still an amazing overclock bro great job

Thanks...its a good overclocker with low volts...but puts out a ton of heat. Need winter back for max clock.

[bluehaze]

Working on this for my 920...man temps go crazy from 4.4 to 4.6 adds 10 degrees even after turning HT off!

I agree. You are on air correct?

wow, thats another great overclock bro. If you only you can keep it cooler

Thanks, I love this chip! Going to play with the volts some more and see if I can get them lower. Had to shut it down, I dont want to run Prime 12 hours with thoise temps

yeah they are a bit high. If you can bring the voltage down some, that'll be great man. That way your temps drop enough hopefully so you can run it stable at that clock.

Sweet clocks bluehaze!, yep some of these chips are hot.

Chicken Patty, I am on water, PA 120.3 6 1400-1500 rpm fans push/pull, dedicated cpu loop, air intake 26.2C, water temps after 13 hrs prime were 32.1C, so 5.9C air to water delta. CPU gradient from core to water is crazy 50C,...10C higher than my i940.

hmm why did I miss that

man these CHips do run hot. Have you thought of a way to improve your water setup?

Heatkiller might give me 1-2C better temps, my air to water delta is already low at 5.9C, best I can do with quad rad, etc would be another ~2C there. Might get 4-5C better temps. Real problem is water to cpu gradient which cant do much about, unless IHS is making bad contact from shape, but again probably talking a few C at max I could gain...though it would all add up. I reseated several times all with same temps.

But I will say, there is no such thing as too much radiator for an i7.

I agree man. Why dont you get one of these puppies

Have Kingpin pot to gpu and one another pot, plus a cpu-pot with hole.
But i can take a pic. if you want to=)

Holy Crap that is big , I wonder how well it performs, or if I could get delta air to water down to couple C instead of current 6C, that would take 4C off my CPU load temp.

somebody over at TPU had one, found a thread about his rig with it, but didn't see any results. According to him if I remember correctly he had like a 6-8 ºc drop at load.

Since you're discussing watercooling an i7 I might as well chime in here. I'm really in shock about those temps some people are reporting, 70°C and up on water?!? What could be the factor for that? I have two PA120.3 and an Fusion v2 (for which I'm still missing the 1366 mounting kit) waiting for the job, but I'm not so sure anymore that that is enough. Since the IHS on i7 are soldered I though that might ensure good heat transfer between core and IHS, so maybe the people reporting those bad temp just have really bad IHS? Or might it be a matter of mounting pressure? So if I lap that W3520, put Coollaboratory on as TIM and somehow manage to get higher mounting pressure, would I still be in for bad load temps? (btw, would it be better to get the D-Tek mounting kit or is something else more pratical to raise the pressure, if that's even needed)

Edit: Any thoughts on this batch btw: 3848A365 ?

Geez.. this D0 stepping is HOT..

With my C0 I could use 4.2 HT On with 1.46V and temps ok... with this D0 anything above 1.4V temps get way out of hand... And what sucks the most, is that I can't bench with more than 4.378GHz...

My watercooler is on its way.. when its done, will post here better clocks hopefully..

[glide 1]

finally got my voltages and temps under control.

8hrs. Prime Stable




and today i was working on this. Prime quick test 1hr.
