Posted September 16, 2016 First of all I would like to say this is my first ever PC build. I learned how to build the PC from watching Linus's videos along with many others. The PC runs great, and I am super happy with the results. I researched overclocking the 5820k and I got an understanding on what I should be doing regarding the voltages and the clock speeds. I started overclocking the CPU the same way Linus explained in his video where he is overclocking the same cpu. I put mine at 4.5 GHz with the CPU Core voltage at 1.3v. I downloaded the trial version of AIDA64 and started stress testing with everything checked except the local disks and gpu. Didn't pass, but I thought that wouldnt be a problem, just raise the voltage. Well I ended up raising the voltage to about ~1.335v (Its where I felt comfortable regarding the temps. It was lying around the 80º mark at that point.); it didnt pass the test. Long story short, I did this process over and over again going lower and lower on my CPU clock. My last stress test was 4.0 GHz 1.33v and it was still failing the stress test. This doesn't make sense to me because everyone else gets min 4.3 GHz on their overclocks. One strange behavior I noticed is that around ~1.33v every stress test easily passed 15 min, but would fail between 1~3 hours. Also, no matter what, if I put on XMP to have the ram run at the rated 2400MHz the stress test would never get past 15 min. Is this normal? Is there something wrong with my system, or did I just get dud cpu that doesnt like overclocking?

Posted September 16, 2016 Not all CPU can be overclocked even when they're unlocked. Reset your bios and make sure it's up to date.

Posted September 16, 2016 Author I am in the process of updating the BIOS now. Plus I just realized I posted this in the wrong category. I thought I put this under troubleshooting. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
