Question Looking to get a stable stock system for AsRock Z790 Steel Legend and 13700k

[fenner1986]

Hey there folks,

I'm running into some issues with my newer system.

Built back in April of 2023, I was running fine for a long while and then suddenly started experiencing oddball crashing in my games (Total War Warhammer 3 and World of Warships).

Current specs are
Windows 10 Home version 10.0.19045
AsRock Z790 Steel Legend
Corsair Vengeance DDR5 2x16GB in slots A2 and B2 CMK32GX5M2D6000C36
i7 13700k running at stock everything with a Corsair H60 Elite on top of it with fresh Mx-6 paste on it (just applied yesterday).
EVGA GeForce RTX 3080 Ti XC3
EVGA SuperNOVA 1000 GT
Running to a dual monitor setup.

The case, PSU, CPU, GPU, RAM, and operating system SSD are all brand new from March 2023, they were running stable up until recently.

Now I can't even get any of the traditional benchmarking software's to run or if they do attempt to run, they throw an instant BSOD. These include Prime95 where I do the shortest FTT (acts like it'll start and then insta BSOD), Intel Burner (Fails after 2 passes), CineBench r23 (For a while I could get a single core result, now I can't even get that to start, multi always throws instant error), and Furmark's CPU burner (can run for a while with 12 threads, but anything more insta crashes it). I can run a GPU stress test just fine with Furmark though.

I have tried updating to latest BIOS (9.03), downgrading to a version prior to that (8.05), then back up, all with default UEFI settings. I have tried it with XMP profile enabled and disabled. I have tried updating GPU drivers (clean installs) and then going back to what I was on. I took out all but one stick of RAM and the 3080 and tried the tests above with just that with no good results. I even went so far as to reset Windows and wipe out every app on my PC and then update Windows again to it's current version, run an SFC, DISM and chkdsk to make sure I wasn't missing anything. I'm at a loss here, why is this system acting so unstable now?

I don't really have any other mobo's I can swap to test things in as this is a fresh build from an old 8700k system that I've given away.

Any ideas?

Below are two screenshots of HwInfo, one at idle and one at a 12 thread load from Furmark that wouldn't crash -

You're running that 13700K with a 120mm AIO?

Correct. It's gonna stay stock and temps on it are fairly decent

So an update here. Went and did a memtest86, all 4 passes succeeded including the Row Hammer tests on both sticks that I had in there currently.

After doing a ton more reading, I decided to try Intel's Diagnostic Tool and bingo, it started failing on Prime Number test. Intel's documents recommended disabling the Turbo for it, so I did and wouldn't ya know it.....success. In Prime95, no more BSOD's. In Cinebench, I can actually start a Multicore test.....

So I guess the question I have now is, do I leave it off entirely or do I instead put it back on and see if I can dial back how far it goes up in Turbo?
