3770K might be hotter due to HT, but they're higher binned, so they usually OC better than 3570Ks. With a H100 they probably can do 5.0 GHz, marginally with temperatures of between 90 and 100, if they get a good chip.

use aida64 cpu stability test to see if its throttling.

Any realistic setup with a sane person would try to keep temps below 70 with maybe 80 max, I just don't get why some benchmarks sites run their tests with such extreme clocks that only people who either don't care about RMAing or have the spare cash & time for replacements would run on a 24/7 basis.

BTW, the maximum tcase for the SB processors is 72ºc,, intel initially had NO tcase listed for more than a few weeks after ivy bridge released and when they finally put it up they listed it LOWER than SB @ 67.4, now it's obvious with tcase & tjunction that you can exceed the tcase without any immediate damage to your CPU, but it also makes sense that exceeding for extended periods would lead to faster processor degradation, or why bother listing it at all.

Now tcase can't really be measured by just staring at coretemp as it may not be accurate but I'd still rather go by something rather than nothing or what some guy on a forum said about running 80ºc all day.

Also as a comparison my 2600k is running @ 4.5ghz/1.320v full load, temps stay below 55ºc

I have decided that keeping things between 80 to a few degrees over is a good goal. Going up to 90 under load is likely only a 100mhz difference anyway. The reality too is that even if something is 90 under load it can spike to 100 with IBT.

As a comparison - my 3570k needs ~1.312v for 4.5ghz however my temps sit around 60-64 during Prime (and 55 during IBT). I'm using a Thermalright Venomous X.

I'd be happy with your volts...

Have you considered replacing the Intel TIM to try for better temps?

I understand that these temps are perfectly safe but I wanted to know if this is pretty indicative of what other people are getting at this speed and voltage? Am I on the right track in terms of temp? I haven't optimised the OC at 4.4ghz yet and may end up going to 4.5 or reducing the voltage as I am only 4 hours into prime95.

I always hear of people saying they get things like 4.5ghz with air cooling with just 60 degree prime 95 load etc... but they could just be running the blend test, BSing, or being in a very low ambient temp.

all depends on your case and fan setup. Difference cases make a good 10 degrees when the air flow is optimal. ATM im using a 3570k stock speed with a Phanteks Cooler passive and never seen it over 50 in Diablo 3.

@one80 I don't see how your IBT temps can be lower than prime temps unless you're not recording the spike temps. IBT has low temps most of the time then it spikes hard. What prime test were you doing? I don't see how you can be around 60 - 64 at 1.312v on air unless you were running the blend test or the ambient temp was really really low.

The difference for me between 4.4ghz and 4.5ghz is .88v which is huge... seems 4.4 is really the point my chip requires a lot more voltage. I had to prop it up to 4.5 when using the offset though or I wasn't stable at idle. I think I got a pretty crap chip I can't even go under 1.7v pll voltage at all or I get a bsod. Reducing the pll voltage just by .1 has really helped though.

I envy the people who are still on 1.2x at 4.5 - 4.6!!!

What are your clocks on the cpu?

Just remember that not all chips are the same. With my own i5 3570K for example, I could get 5.0Ghz stable on Air (granted, I have a golden chip apparently). If you hit a sudden jump in voltage at a certain point (like how you did at 4.4), usually enabling PLL Overvoltage will help alot. It doesn't really affect any power saving features, just make sure to set the actual PLL voltage (not auto).

Does it allow a vcore reduction if the pll is higher though? I noticed that reducing the pll voltage reduced my temps but the vcore needed was the same. I will do some reading on overvoltage then.

I've downloaded the latest version of IBT (was running 2.50) and tested again - it still sits around 55ish and will spike into the low 60s. I usually run Prime Blend for stability testing - that sits in the low-mid 60s and occasionally jumps to 70, then drops back. Prime Small FTTs gets the hottest at around 77 deg.

Sorry to hijack OP's post

Ah ok the small FTTs temp makes more sense. Blend results in lower temps. BTW IBT shouldn't be spiking for less than prime small FTTs gets. That's really odd. For me IBT spikes a lot higher than prime95, which is really its intended purpose. LinX seems to stress it the highest though - like 15 degrees higher than prime.

Don't forget about AVX instructions, I believe it can also affect temps, http://www.overclock.net/t/1061278/linx-with-avx

That appears to be for Sandy Bridge not Ivy Bridge and it may actually raise temps if it is increasing performance.

Why wouldnt Ivy support avx? They also state it does under 'essentials: Instruction Set Extensions' on intel's site for 3570k spec.

I was only referring to it since you guys seem to have a discrepancy between cpu temps between prime95 & IBT so it's pretty relevant if one of you have it and one of you does not. Or even if one of you is running an older version of prime95 without avx support while the other one is running the newer one.

AVX requires windows 7 service pack 1.
Also the latest version of prime apparently runs AVX aswell.

It's also the latest news on prime95's website from May 15 2012.. http://www.mersenne.org/

Hope that helps!
