Another noobie trying to overclock his 920 c0/c1

post #1 of 11
Thread Starter 
Hey OverClockers,


I've been spending a lot of my resources lately preparing my rig for an overclock. here is the setup, I can include photos later if it would help.

i7 920 c0/c1 @ 2.66 (stock)
Arctic Freezer 7 heat sink/ fan
6 GB (3 x 2GB) Corsair RAM
ASUS GTX 680 GPU
Corsair 750w Gold PSU
SSD and mechanical Drive
ASUS P6T Mobo rev. 1.xx says (12)


I have been running CoreTemp, CPU HWMonitor and Prime 95 for all my "testing" As it stands, after about 20 minutes of the blend or small FFT tests my "CPU TIN" is reading 75C and my cores are averages of 68-71C whatever SYSTIN is, thats 42C and AUXTIN is 11C

I am not trying to get the highest CPU clock possible, I really would like a modest 3.6 or 3.8, something that is stable, I'm beginning to wonder why my setup runs so hot! I have the fans setup as linear as possible, having a "strategic flow" that its moving efficiently. Do these i7's just run hot? How hot is too hot, and I've looked at some of the guides but I just want some reassurance and some pointers if you guys don't mind.

Thank you!

Sean

Those temps are fine, but what clock are they at ?

dunx

P.S. At 4 GHz my i7-960 reaches a maximum of 80 degrees at 100% load using a Corsair H70, ( which doesn't bother me....)

That is at the standard clock of the i7 920 c0/c1 which is 2.67ghz, at 100% load after about 20-30 minutes of stress testing.

Your cooler is rated for 130W, well the i7 920 is a 130W CPU so its doing just fine for stock.
Thats pretty much all its good for. The C0 stepping requires more juice too so your going to need a top end air cooler to get this thing to 4Ghz, for 3.8Ghz youll probably still need to.

Ah, damn. Well, I looked around for some time before I got that one. I wish I could find some resources for good coolers to overclock the 920.

Noctua NH D14 is one of the best and still available

Thanks for the recommendations, I'm looking into the Noctua NHd14, thermalright silver arrow, and the arctic freezer 13CO if anyone has any experiences or recommendations based off those I would love to hear it. Also, I'm open to liquid cooling if it's economical.

I also just want to know, if I crank it up to 4ghz can I expect the CPU to crap out quickly? (<2 years) is it purely based on temps? Any input is appreciated!

Look at the Noctua Nh-u14s. It is better than the NHD14 apparently b/c it has better wicking material than nhd14.

As far as how long the cpu will last it depends on the volts and temps. Keep temps below 80 -90 for 24/7 and volts below 1.35 if your concerned about longevity. But there is a lot of people running more volts that 1.35 and have been since 2010.

Turn off hyperthreading and try overclocking like that especially with that weak cooler.

I went ahead and purchased the Noctua NH-D14, it looked like some of the other variants weren't compatible with the LGA1366 socket (i7 920 here) and the nh-d14 had great reviews both among OC enthusiasts and various online comparison blogs. I just have a couple questions.... Lets imagine for a moment that I only cared if the processor lasted for about a year. Any idea what kind of clock speeds I could squeeze out of it? On the other side of the coin, lets imagine I wanted to OC but realize that it will definitely decrease longevity (but wanted to get some speed and prolong the integrity of the chip as long as possible), how can I maximize both of those two metrics when OC'ing?
