4770k and higher (than others) temps while stressing. 4.5Ghz+

post #1 of 7
Thread Starter 
Hi. I have a 4770k (Maximus vi hero motherboard) and it's under water with a corsair h100i. My questions is this, for example...

My 4770k is set to 4.2 at 1.030 volts adaptive.. And when running intel burn test, prime95, or Aida 64, my temps hit about 80-82c under full load. Then when I run it at 4.5 at 1.287 volts adaptive, I can't even run stress test because it reaches the max 100c and I have to stop it before I degrade the cpu. However, at 4.5, while gaming, it hits 60-68c depending on the game- Battlefield 4.

So my question really is, how do some people run at 4.5 and above, and only hit 80-90c when stressing? I was reading that someone hit 4.7 at 1.25, and while running prime 95, he only hit 80c.

Because I just bought my h100i, Im going to keep it. I do plan, within the next couple months to a year, to buy a custom cooling loop from xspc. I have a 780 sc acx, and also plan to cool that with water also.

But seriously... 80c while stressing, and at 4.7?

When I do upgrade to a custom cooling loop, I plan on adding 3 rads to keep it quite, and the possibility for my "cooler" water... If that's possible. thumb.gif But will a custom loop cool the cpu better? 4.2 is the highest I can go, without throttling my cpu, and the possibility of it burning up.

If you're going to run these types of stress tests then make sure you use Manual instead of Adaptive. There is no reason to keep using Adaptive, just switch to Manual mode and enable C states - you can limit to C3 as that'll give you 0.7v.

Lastly, not all chips are equal and I don't mean just the frequency lottery. For example, I see people on air run cooler than I can get my chip under water (see sig).

add: to give you an idea, I use XTU Bench (not the Stress test) - when I run x45 @ 1.33v / x43 @ 1.21v, it gets me to 83 degrees. This is Manual mode with C3 enabled. If I tried that with Adaptive, the volts would be ~1.41v.

Not everyone testing haswell chooses to run AVX2 (latest linpack) and FMA3 (latest prime95) instructions. Those tests will truly test your cpu to the fullest and produce heat nowhere near the daily use.
What you are seeing is quite normal if you run those heavy tests. I also get 30C difference between daily gaiming and FMA3 for example.

Also, in your case 4.2 @1.030v is a bit high though, you shouldnt be exceeding 90C at those volts. Consider doing remount.

I never said I exceeded 90c at those speeds and voltages. During intel burn test, 4.2 at 1.030, the most I hit was 82c. Thanks for the info on the other part

Custom loops will always outstrip AIOs, however I suspect deliding would help a lot in your case as your voltages are not bad.


Also, don't run adaptive, go manual.

The fact that you tried to run a stress test on adaptive shows you have not read a guide. There's a link to my guide in my siggy.

 

 

73C was achieved as noted in the guide on 1.25v with Prime 27.9 on small FFT. On 4670k, NOT 4770k. With Noctua D14. So there are a few things to note: One, we disregard adaptive. Two, 4770k is hotter than 4670k due to HT. Three, I'm assuming you live at a place that is not too hot. When I first wrote my guide I got people complaining about temps, later on revealing that they sit in a 100F room with their computer. Four, you might want to ask yourself why you are running Prime, especially IBT. Five, I am assuming you are running 27.9 Prime, not the legendary 28.4 version. I'll post my temperature chart for your convenience if it helps.

 

Don't forget that voltages make a larger difference in temps than clock speed.
