Max Intel i7 3770k working temps?

[MrSolecism]

I got an H100 and have my prosessor overclocked to 4,2 Ghz with a boost feature. My max temps under 100% load is 70-74 C. Should i be able to overclock to 4,4 Ghz?

You might wanna check your voltages. You're not on auto overclock are you? Pretty much every 3770k should be able to do 4.4ghz.

Try 1.25V CPU VCORE. Never use auto overclocking utilities, you're better off doing it manually. At around 75 degrees many CPUs will begin to throttle, meaning that they will sacrifice some performance in order to keep their temperatures sustainable. Good luck.

Tjmax is 95C I believe. However I would recommend you stay under 85C at the most. Also I really don't recommend you take the auto overclock route. You're much better off doing it the real way.

 

go back to stock speeds and see how low you can set your CPU vcore using offset. Once it becomes unstable you can start to up the voltage and freq.

[tabuburn]

Anything over 85C and the CPU will start throttling performance to protect itself.

Why go back to stock speeds? He wants a 4.4GHz overclock, he might as well lower the voltage from there.

not true. It will not throttle until at least 90-95. However running your CPU at a constant 85C will make it degrade faster.

Because thats how you overclock. You dont just say "I want to hit 4.4 so Im gonna start from there". Overclocking is much more time consuming. Too many people take the lazy route and end up with unstable machines.

 

the point of finding out the lowest voltage you can go with at stock is so you can draw a freq/vcore graph and find out when pushing for higher overclocks requires too much voltage. That way you can find the sweet spot for your chip where you can apply the lowest amount of voltage with the highest possible overclock. Hope that makes sense.

 

EDIT: double post, my bad

Almost all 3770Ks are completely capable of 4.4GHz, there's no point in going back to stock unless it's a high overclock.

And if it's unstable, stress testing programs like OCCT will show it. You're wasting your time finding the lowest stable voltage at stock speeds if you're not going to use stock speeds to begin with.

A important pat of overclocking is characterising your CPU i.e. understanding how it behaves. This was especially important back in the Core2/Phenom II days when overclocking was harder than just upping the multi and calling it a day. I still encourage people to take the long route. Its more rewarding, and at the end of the day you will understand more about your system. Do no underestimate the importance of finding out how your chip behaves at stock.

Wrong again. also I wouldnt recommend you use just OCCT. Often times Prime95 will pick up errors that OCCT wont and vice versa.

I said "over 85C". Depending on the quality of the silicon on the die, it might start throttling itself at 85 or higher. I also did not say to run it at a constant 85C. Even so, it's the combination of both high heat and high voltage that degrades a CPU's life faster.

Right sorry, misunderstood you there. And yes it is the combination of voltage and high temps that degrade a cpu.

There's more to overclocking than just the temperature. Your particular CPU may simply not be capable of running over 4.2Ghz.

[MrSolecism]

Thank you so much for all the answers! Really appreciate it! I think I am going to read more about overclocking and do it the manuel way. That will probably also give me better temps!

[MrSolecism]

Final result became 4,4 Ghz with 73 C at max load

[Art Vandelay]

I think 90 degrees under prime 95 load should be the point where you abort the test. The 8k FFT on prime95 usually produces the maximum temperature.

[slasher0161]

That still seems quite hot for 4.4ghz with a h100, I know i7's run hotter but if my i5 does 4.4 max temps of 76c with a hyper 212 I would hope the h100 could do a better job than that (thats with 30c ambient).

[orangecat]

Turn your voltages down a tad then see your temps are not really high but for that clock speed they should be lower.

[grayperview]

Everyone's chip is different but you should be able to run at 4.2GHz at around 1.188-1.224v....even a little less maybe

 

First off, I would find the minimum voltage your chip runs stable at stock speeds. then gradually increase the overclock and voltage, saving each profile as you find it stable. 1.050v has been known for stock.

 

Say stock, then 4Ghz followed by 4.2Ghz and so on...

 

Eventually you will probably end up around 4,5ghz stable running at around 1.29-1.32v, if you manage that you could increase it further, but you will risk degradation at an increase rate on your CPU.

I am running the i7 3770k at 4.4Ghz @ 1.25V with this on top of it... with a gentle typhoon 1850 in push. Max temps during 3DS Max renders are around 80 Celsius.

Also, do use the guide linked by super_skank above, it's awesome.

As long as your CPU does not throttle I personally think any temperature is ok with ivy bridge as long as you are not pushing the volts to high. The IHS on ivy bridge sucks so they tend to run really hot no matter what kind of cooler you have. I am just about 12 hours into a 24 hour stability test on this i7 3770k at 4.4ghz @ 1.21v on a Gigabyte z77-ud4h with a Coolermaster Hyper 212+ with a Nocuta NF12. Max temp so far is 91 but it was only during the hottest test and most of the time my temps are around 80-90. I honestly don't care if my cpu degrades a little because I do not plan on keeping it longer than 5 years anyways. My cpu does not throttle until 95 C so for me keeping temps under that is fine for stress testing programs. In real world applications and gaming the CPU will not even touch 80 C.

 

Also 0 errors in event viewer since I started the stabiltiy test at around 12:42am this morning.
