i5 4690k super high temps with Linx

post #1 of 8
Thread Starter 
Hey guys,

I've overclocked my CPU to 4.3GHZ, 1.23V, internal PLL overvoltage: OFF. Didn't go any further because at 4.4 it started to crash on stress tests and I basically wanted to use a lower voltage than default.

Temps were great whilst running Intel Burn Test and CineBench, hovering at 60C maximum. Running Linx was a different story though, the maximum it went was 92C, which is insane, I was wondering if it's this particular stress software that does this or is there's something wrong? I never ever saw temps this high.

Thanks!

Specs:

i5 4690k @ 4.3GHZ - 1.23V
Corsair H100i GTX
Kingston HyperX Blu 16GB @ 1600mhz
Asus z97 PRO

Yes it is the stress test. It uses advanced floating point operations almost exclusively and they will drive your temperatures sky high.

Ah ok, thanks for the quick reply. I can rest easy then smile.gif

I'm gonna take this chance to ask another question if that's ok.

Regarding overclocking and voltage, is it possible that even though an overclock is stable on all stress tests + gaming, that too much of a low voltage is "hindering" the performance? Even though it holds stability?

I'm asking because my stable OC right now is x43 - 1.23V + x40 (uncore) - 1.2V. I don't need more clock, so I'd like to try reducing the voltage but was wondering if it could be hindering performance.

Thanks!

^ anyone?

No, not usually. If it is actually stable you should not see any perofrmance drop.

Try running something for stability test that also gives you a score, like x264 or cinebench.

This is normal.

LinX, Intel Burn Test, and a few other programs use something called Linpack, which will drive your CPU to extremely high loads. Temperatures will be 25-30C higher than typical loads you'd get with say, x264 encoding.

The only way if you want to be able to run these tests is to delid your CPU. Bear in mind the risks of doing so.

No - too low a voltage will not hinder, provided it is stable. That's a big if though.

I personally believe that no CPU is stable unless it's been stressed out by a program like Linpak, because it puts more load on the cores themselves than anything else. I'd then combine with Prime95 Large FFTs to test the uncore and MCH, followed by HCI MemTest for the RAM itself.

That won't assure stability. The problem with such programs is that they can take a very long time to reveal any problems and if you find out the hard way, you could lose many hours of work.

I think you misunderstood. Running such benchmark will allay the OP about performance. Yes, it takes much longer for detecting instability, but it doesn't beat the hell out of your processor or reduce its lifetime significantly. I use a short run of prime95 1344/1344 FFT as that usually shows any instability pretty quickly without raising the temps astronomically high, followed by x264 and realbench for longer periods.
