I have an OCUK 2700K OEM running on Asus P8Z68-V and managed a stable 5.ghz @1.41v temps maxed at 71C using Corsair H50 single fan. Ran 10 runs of IBT and all is fine. Not sure if temp is to high as first time since 486DX days that I have used Intel

But your CPUID had show as "Rejected by CPU-Z 1.58" (not validated) and it look photoshop to me !

demonstag · 11 Nov 2011 at 19:55

I have just re run the validation. No photoshop involved

Nice one damonstag!

Photoshop more effort than actual results lol

What with all the offers on Z68 motherboards this is getting even more tempting...

The H80 could definitely do 5GHZ if that's what your asking.

The cooler Gibbo used is basically an unbranded H80

He used too very high RPM and noisy fans with it though!

Well so far I have my 2700K at 5Ghz at 1.345v, its been running prime95 for the last 6 hours without error and the temps haven't gone above 66oc on any of the cores. Loving it!

Impossible @ 1.345v for 5GHz ? You must have lucky cherry golden chip then!

Andromeda1983 · 11 Nov 2011 at 21:42

Heh dont worry bulldog I spoke too soon, prime95 error'd about 5 min ago

zoomee · 11 Nov 2011 at 22:02

Try running IBT on maximum with 8 threads set and you can kiss them sub 80Degrees C temps goodbye lol!

demonstag · 11 Nov 2011 at 22:24

managed to reduce voltage to 1.375 and temps down to 68C. I will need to upgrade to full watercooling for any higher.

Obviously not stable seeing as your last post was 40minutes before this one lol

I'm interested in hearing about the longterm users - It seems the more I play with this chip, it needs more vcore to become stable!

For example - last week 4.8Ghz needed 1.32v (fully IBT and prime stable)- This week I'm having to use 1.36v!.

EDIT: Scrap that - forgot about my memory upgrade doh!

Left prime95 on overnight. My 2700k requires 1.41v for it to be 100% stable.

Ran IBT no problem, Will run prime overnight to see, but I think Ive reached the limit until I get better cooling. Is running above 75C safe? :confused:

with AMD I never went above 50C

Ghostdog · 12 Nov 2011 at 01:32

General concensus seems to be "+70oC is a bit high" +75oC limit most people are recommending on full load.

I used IBT on my 4.4ghz and the temp change from Prime95 to IBT was as high as 10oC. I have my H80 set to the lowest setting. Wont be possible past 4.5ghz which is a shame. Very quiet atm.

I already answered this:

The maximum temperature you really want to aim for is around 70°C, perhaps 75°C tops.

Ghostdog · 12 Nov 2011 at 06:10

My chip got to 5ghz to

Running a bit hot in IBT, 82oC. Screenshots not intended as proof. IBT did fail eventually, but high temps probably not helping (set to high, 8 cores). Prime95 running diffrent test for the last few hours hasnt had any problems. Dont want to stress test more until i improve cooling, everything i use my computer for is working perfectly.

I have a h80 cooler, any suggestions on getting my temps down another 10oC? Its in a HAF-X case. 2 very high RPM fans on the rad?

Ghostdog · 12 Nov 2011 at 14:33

Last nights OC has failed this morning, not at 5ghz stable yet. Going to have a read about and see what i can change.

demonstag · 12 Nov 2011 at 17:11

Is it normal to have upto a 10c temp difference between core 1 and core 4????

It varies between chips of course, but generally yes it is normal, I believe someone on here had a 13 degrees difference! Don't worry about it.You could try a re seat of your cooler with new paste if you are really concerned, but I doubt it will make a great difference.
