i5-4690k really concerning temps?

[Deus Gladiorum]

Hey everyone, this weekend I OC'ed my i5-4690k to 4.5 GHz at 1.2 Volts and now I'm really concerned. My temperature in OCCT seems alright, only going to 73 absolute max after 2 hours of stress testing on it, but otherwise passed the test in terms of stability. However, in Intel Burn Test I was hitting 85 and but managed to complete 10 passes without fail on standard, and Prime95 almost immediately had me at 90 degrees. I was way too concerned to let that go, but I think one of my workers kept failing, but I was too concerned with that temp to pay attention. However, according to CPU-Z my CPU isn't throttling so honestly, should I be concerned?

That's a god ambient at which to conduct your tests. I think you've done a thorough job with finding your OC and getting a feeling for temperatures.

In my experience, I'd go for a higher OC based on P95 v26.6, because like most folks, you probably won't run any apps which are AVX / FPU intensive enough to force Windows to crash. Considering your processor's unique behavior, I think at 4.5, a Vcore of ~1.230 is most likey adequate to keep your rig stable using P95 v26.6 Small FFT's with temps at ~80C at 22C ambient running your 212 EVO.

As you get more time to experiment, you may find that these settings are pretty close to correct. Nevertheless, what really matters at the end of the day is that you're satisfied with your Vcore, temperatures, OC, system capabilities and overall performance based on what you've learned, as well as all the testing you've performed.

Yea, thanks a lot for everyone's help. I'm still gonna play around with this OC a bit. Right now I'm quite annoyed because it's 6am over here and last night I set a blend test for Prime95 thinking I could pull a good 6 hour run overnight. Unfortunately, my PC ended up going to sleep after only half an hour and so all that time was wasted and so I'm quite ticked off. It must be because all my power savings options are enabled in my BIOS -- options I'd turned off back when I'd OC'ed my FX-6300, hence why I don't remember that going to sleep during stress tests. What's a quick solution for that, just to turn off sleep mode in Windows and not in the BIOS?

Right click on your desktop and click on Personalize. In the lower right-hand corner go into Screen Saver. Near the lower left center of the screen click on Screen Saver, then select none. Click on Apply and OK.

Also, go into Control Panel, Power Options, then to the right of the selected plan, click on Change plan setting. Next click on Change advanced power settings.

Click on the + next to Sleep and the + next to Allow wake timers, then change Settings to Disable. Click on Apply and OK.

That should do it.

I was hesitant about selecting a best answer since no single post answered my question, but I'm glad Breezy selected it. Regardless, whatever I would've selected would've been your answer. I'll probably have a few more questions though. Currently about 2 hours into a Prime95 run. Gonna see if I can hit 6 hours.

 

[Beezy]

Well wait to see if you get safe and stable. But computronix undoubtedly gets the vote

 

[Deus Gladiorum]

Well I'm just under 4 hours in and I'm still going strong on this blend test. Temps go anywhere from 60 to 89 degrees max, but so far things look good.

 

[Deus Gladiorum]

Alright, just finished 6 hours without error on blend. I guess I can say I'm stable now!

Now to OC my GPU...

 

[CompuTronix]

Congrats!

I have an EVGA GTX 770 2GB SC which I was able to OC using EVGA Precision X. OC on the Core was 1160 (1254 Boost) and Memory was 2050. Your make and model will probably OC a bit higher.

Also, if you or BEEZY selected me, I don't see it anywhere.

Sorry for not adding anything useful to the discussion, but I have noticed my temps skyrocket after downloading the latest version of Prime (28.5). Should I revert back to v16.6 for stress testing my OC? With a vcore of 1.2 I was hitting 84C in Prime 28.5, which is way too hot for me..

 

[CompuTronix]

That's my recommendation. I think the majority of our readers are gamers, and don't run any software that makes use of AVX or FMA instructions.

For those that run FPU intensive software for high-level number crunching, compiling or media creation, I recommend that they use those softwares for stability testing.

Running P95 v28.5 Small FFT's or AIDA64's FPU test will cause your processor to ring the fire alarm and hit throttle temperature, unless you minimize your Vcore and OC to something less than what is achievable within recommended limits.

 

[Alex Kelly]

Thank you very much for the advice, I appreciate it.
I might actually keep the new version of Prime, as it's kind of nice knowing that my OC is okay even when handing the most intensive workloads. It's also given me a rounding error for the first time ever, when normally I just BSOD if my settings aren't stable.

I don't think overclocking my GTX 770 will net much. I have a GIGABYTE Windforce 3X, with a base around 1189 MHz and a boost of 1254 MHz, so even at stock I'm about equal to your overclock, CompuTronix, haha. I might try anyway, but right now, this thread has been solved.
