Hi, I recently upgraded from a 6600k to a 7700k(yes, bios is updated) and this is actually the 2nd 7700k I've tried. The first needed to be undervolted just to keep temps in check stock, so I exchanged it. This second chip runs a bit cooler, but still hot so I upgraded my cooling to a h115i. Thing is max temps are still high. Idle is fine between 25-30c but under load while in the 60-70s most of the time, temps will randomly spike into the 80s, or even 90s if I try to oc and run occt.
And speaking of overclocking, I can run realbench and xtu for hours stable at 4.9ghz and around 1.30v with realbench maxing at 88c. I tried for 5ghz but couldn't get it stable going up to 1.36v and temps where already in the 90s running realbench. So, I figured I'd settle for 4.8, which is also stable for hours running realbench and xtu at 1.28v and a max temp of 84c which I can live with. Problem is these setting fail instantly when trying to run occt. Occt fails after 5 minutes of 4.8ghz at 1.33v in bios with temps hitting the 90s, including cputin. The best stable oc I can get running occt is 4.7ghz at 1.28v. Anything more fails, even with huge voltage bumps.
Is cputin supposed to match the hottest core? Also shouldn't a h115i keep this chip cooler than this? And lastly I read that every 7700k should be able to hit 4.8ghz around 1.3 volts, yet I'm unstable at anything past 4.7. Is there something wrong with my chip that temps are so high and there's so little overclocking potential? I know you have to play the silicon lottery, but this is ridiculous. Thanks.
