Hardware before I get to the issue.
Gigabyte Aorus Xtreme z390 with i9 9900k on latest F9 bios
32 gigs of Gskill Trident Z DDR4
EVGA 3080TI FTW3
Samsung 970 pro NVMe 500 gig system drive, 2tb 970 evo+ NVMe, 2 1tb 960 evo 2.5 sata ssd's, and 1 2 tb WD hdd.
All running on a Seasonic Prime Titanium...
Got it at 5 ghat 1.33 volts. Uncore is at 4.3. I enabled XMP so it would set the default timings and voltage but I down clocked the sticks to 2133. On the overclock.net aorus owners thread posted above they recommended running prime with avx disabled in the local.txt and with a custom fft length...
When I managed to get it to run prime it hit 104C once, then the fans on the h115i spun up and were able to keep it below 100. TJMax is also set to 110c just as yours is.
I did the same with the voltage, just never found a happy spot. LLC is currently set to Turbo, the extreme felt like it...
Before all this I ran memtest for hours with my memory at its stated 3600. After I find a sweet spot for the processor would it be possible to put the memory back to 3600? Maybe give the memory controller a bit more voltage?
Well hell, all the guides I'd followed had me setting the xmp profile first. I took the memory down to 21 3 3 and changed nothing else and prime is running fine. Fine as in its been running for 5 minutes without crashing ,which is five minutes longer than I got before. Now it's thermal...
I think I may have a really poor chip. My goal was to shoot for 5ghz, and that's currently what I'm running at now, but it's not stable. I've been messing with my overclock for days trying different things to no avail, so last night I started downclocking it. Even at 4.8 my system locks up...
So here's my dilemma. I'm currently rocking a custom water loop that is way overkill for what I'm currently doing. It's sitting in a corsair 900d, so it's massive. I moved into my fiances and there simply isn't room for this system so I was looking at getting a new case and using an aio cooler...
