After Overclocking, Problems Ensued.

[Snake_skull]

Greetings LTT Community,

I recently attempted to overclock my CPU (i5 4690k with a Hyper 212 Evo heatsink), And was Stable and successful! ... or so I thought.

I overclocked at a friends house, and stress tested using Cinebench and H. x264 from r/Overclocking. Along with games like Rocket League, Fallout 4 and Battlefield 1.

 

After I got home with all my stuff and put everything back together.

I booted up, with the same Bios settings that had previously been determined to be 'Stable'. Booted up and got into the login, attempt to login and BLUE SCREEN.

"Eh, Probably just a hiccup" I thought. Restarted into Bios to make sure I was using the right settings.

Boot in and login just fine, and just to be sure I was still stable, I ran H. x264 again. When running the test I reached 52.3% completion and the test paused itself and my CPU usage went from 100% to 0%, With the benchmark just staying still. Not frozen, just paused.

I wait a little bit and it continues...

Then the problems started showing themselves, my screen went black for 3-4 seconds and came back on. "Weird..." I thought...

Then my screen starts going a little crazy,

 

I have no way to possibly describe it other than it looked like two separate overlays of the same image just have a seizure for half a second then stopping. Or it looked like the stereotypical computer screen glitch that happens in the movies when a hacker gets access.... (I have no other way to describe it)  Note: The Test was still running during this.

 

I NEVER CRASHED FROM THE STRESS TESTS.

 

After becoming more concerned, I restarted and lowered my Core Clock to 4.4 Ghz (On a 1.32 vcore)

 

Opened back up just fine, ran Cinebench and the same issue arose, not immediately but halfway through the test.

 

Eventually I just reset all my progress and now am running back at stock clockspeed and ratios. But still have issues with the stress tests.

 

Is it my PSU acting up, my CPU or my GPU....

Note: I hadn't run a CPU stress test (other than Firestrike and Timespy) on my computer before this so I don't know if the problem would have happened then.

 

My PSU is a Really shitty 600w 80+ efficiency rating power supply I got for $50 at best buy after my First PSU killed itself.

My GPU is a Asus Strix GTX 1070, Not manually overclocked.

And my CPU is a i5-4690k.

 

Please help :C

r/Overclocking sounds like a huge joke if they think Cinebench and H. x264 is a stress test. 

 

AIDA 64 always and forever.

 

Realbench if you want a super hardcore stable OC.

i would start with a simple CMOS reset, that will probably help also those benchmarks are shit for stresstesting, use Aida 64 and run that for 24h before you consider anything stabile

Not really helping me... Thanks for the advice though.

What? By pointing out that cinebench and x264 are completely unsuitable for stress testing an overclock. Alright kid....

Unless it is Seasonic, XFX, or a decent EVGA or corasir one that might be your issue.

 

What model is it?

Hey there!

 

I have a i5-4670k here that runs 4.4 GHz relatively stable on 1.26-1.27 volts with really high temps on the intel burn test (80-85 degrees C). So since the 4690k isn't really much different I'll have to say that 1.32 volts is really high, and probably pushing it too high for continuous use.

 

I've read multiple times that for the 4670k and 4690k 1.3 volts is actual the max you want to go as can be seen in this topic: http://www.tomshardware.co.uk/answers/id-2739638/4690k-overclock-max-safe-voltage-temperature.html 

 

Why don't you try aiming for a 4.2 clock at 1.25 volts and if it's stable upping it to 4.3 and later 4.4 to see if it works.

 

Let me know how it turns out for you, and good luck!

[RudiNL]

Oh and as stress testers use Intel Burn Test or Aida64. Those are the ones you can trust upon. Cinebench is not really a stress test but so much more a benchmark like @DildorTheDecent already noted.

 

Compare it to stress testing your GPU by running a game or to a lesser extend Unigine Heaven instead of stressing with FurMark.

 

Again, cheers!

600w. I have no clue about an exact model.

 Clear cmos start oc again, use aida64...
