New to this, 2600k @ 4.4Ghz

[DrD0ctor]

I'm new to this, got my i7 2600k to 4.4Ghz with a CM V8 cooler. I think my temps are pretty high though. This has been running for ~30 mins but I plan an letting it run while I work tonight, so roughly 8-9 hrs. Problem is, like I said the temps seem pretty high already. Any of you pro OCers have tips?

temps are ok for p95, you need to disable something in the bios to run at the full 4.4. cant remember right now, it will come back to me if somebody does not chime in. cpu spread sprectum set to disable.
run 95 blend max memory if you arent doing it right now

[DrD0ctor]

Also, I had it at 4.6Ghz earlier, ran p95 for 45 minutes before getting the x00000101 BSOD, temps were hitting mid-high 80s, any insight on that?

Also, glad to hear the temps are okay thus far, I'll update this later tonight, but I suppose I can rest a little easier!

Also, I'm using the presets that are on my AsRock z68 Extreme4 Gen3, maybe I shouldn't do that? Anybody know some more details about those premade settings? I'd love to be stable at 4.6, it just felt perfect

Thanks!!

probably not enough cpu voltage.

[DrD0ctor]

I'll try it again tomorrow possibly, but mid-high 80's are dangerous temps, no?

Also: Yes I'm running the blend test, max memory

[---TK---]

I do it no problem for a 12hr run of p95. your 24/7 temps will be much lower. looks like your max is about 4.6ghz with hyperthreading with your cpu cooler. I wouldnt go higher

[sykozis]

I'm hitting 70C at 4.0ghz - 4.4ghz running F@H after only a few (5-10)minutes. I peak at 68C running P95 blend after about 15mins using a Freezer 13 (non-Pro). I had to remove my CNPS10X because it would hit 60C loading Windows. Found out the base wasn't machined properly and had some freakin HUGE gaps....I'm talkin 1/16" gaps. I'm trying to flatten it out but may end up ordering a new cooler again cuz I don't think I can take that much off the heatpipes...lol

Tommy, you told me 70C was bad.....lol

[---TK---]

70c its very acceptable to stress test. I wouldnt run 70c 24/7. FAH I would try to get it 65c max if possible. I stress test in the mid to high 80`s at 4.8ghz HT.
@sykozis how many cpu threads does foh use? if your not using 8 threads you can try turning off HT and see if that lowers your temps

F@H will adapt to the number of "cores" the OS sees. So, technically I can disable HT and F@H will switch from 8 threads to 4 on it's own.

[---TK---]

well will that hurt your points doing that and what would the temps savings would you get? you could most likely raise you cpu speed higher to compesate for just having 4 threads and still have better temps. just a thought

[sykozis]

With the i7 870, disabling HT was about a 25-30% drop in PPD.... Need to bring some tools home monday and take a few measurements to see if there's any chance of fixing this CNPS10X that Zalman screwed up making. None of the heatpipes were flat....instead they were all up on angles. I should be able to get 65C load IF I can get them all flat and smooth.

Xtreme1979 hooked me up on this one. Thanks dude


"For those who are getting a bclk of 99.8 check in your UEFI/BIOS and see if spread spectrum is enabled or on auto. If so disable it and check your bclk. Should be at 100mhz now. "

[sykozis]

I always just bumped up bclk up by .1 to correct it....lol

Guess I'll go disable Spread Spectrum now.

[Xtreme1979]

Disable SPREAD SPECTRUM to get a steady 100mhz BCLK.

[---TK---]

believe that was already touched before

Yeah it was sorry missed it.

Well after 9 hrs of p95 the temps didn't change from the original jpg I posted, and the computer never crashed. So I'd say 4.4 is extremely stable. I'm going to try bumping it to 4.6 and raising voltage and see what happens.

I understand people do it all the time, but I feel uneasy letting my cpu sit at 80+ C for over 9 hours. Are there really no risks in testing so heavily? Do cpu's never burn out?

Like I said I'm new to OCing CPUs, so excuse my ignorance.

[---TK---]

Go for it and stop test if it his 90c. I have primed in the low 90c at 4.9 but stopped the test after 2 hours lol

The CPU should throttle before any damage is done.

[---TK---]

It doesn't throttle at 92c happily running p95 stable at my CPU speed. Lol. I wouldn't recommend doing that though. Mid to high 80's is ok for just 1 p95 run. Remember these 2 bsod codes 0101 and 0124. Raise you CPU volts 2 steps when you encounter them. Gl

don't know if that's just with SB, but my base clock still fluctuates slightly with spread spectrum disabled. is that normal?

68C peak in P95 blend test at 4.4ghz after a few hours of lapping my CNPS10X....

[DrD0ctor]

I'll give it a shot, for the most part my most significant worries are eased. For one thing at least I know 4.4 is 100% stable, secondly I was worried that the temps were abnormal and I'd have to reseat my cooler. The mobo tray in my case has a space behind the cpu but it's not big enough/it's not centered enough behind the cpu for me to fix it without disassembling the entire system.

So either way you guys have helped a lot so far, thank you so much

[sykozis]

My processor is running a lower voltage than your's, which may explain why my temps are lower. I'm managing 4.4ghz on 1.26v.

[---TK---]

after around 4.4 you have to start jacking up the voltage. 4.7ht idle is 1.424v load 1.408v
4.8ht 1.460v idle 1.440v load
doesnt matter much to me because half the time I`m using SS, the other half full speed.
my chip needs a lot of voltage to be happy. just a plain average chip I got
