14900kf unstable at stock

[Enrez]

I’m currently running a 14900kf at stock, but I keep getting crashes and bluescreens.

Whenever I reboot there’s a very high chance of a few bluescreens before it allows me to get back into Window “SYSTEM_THREAD_EXEPCTION_NOT_HANDLED”

I bought the 14900kf and launch with some new ram, “Corsair Dominator Platinum RGB DDR5 7200MHz 32GB” I’ve tried switching back to my sticks “Corsair Dominator Platinum RGB DDR5 5200MHz 32GB” But the issue stays the same.

I was using a 12900k earlier with a ASUS ROG STRIX Z690-F GAMING WIFI motherboard, that I tried using with the 14900kf, I thought that the motherboard might have caused the crashes so I switched it with ASUS ROG MAXIMUS Z790 HERO, which didn’t solve the problem.

I’ve ran OCCT cpu test, first time I did it instantly gave a “WHEA error” Next time I ran it, it gave a physical core error. The time after it finished it with no errors.

Currently there’s no Overclock, I really just want something stable that is “good” I’ve tested with Intel® Extreme Tuning Utility AI Overclock as someone said it could make it stable, which didn’t solve the problem.

I’ve also played around with XMP settings, it seems like activating it makes it more unstable, but I haven’t done a lot of testing. I’ve ran Memtest86, which completes without errors.

Crashes:
It crashes when booting
Games are crashing, at no particular time, seems just random. (Dota2 CS2 CK3)
- I’m able to play these games, but there’s a high chance of the game crashing during a game, sometimes also bluescreening.
When I play CK3, it crashes very often, at the start it would do it all the time, but after limiting FPS to 60 it works for longer, but it eventually crashes.
It also crashed during 3 hour long OCCT CPU stress test.

Drivers and bios
I’ve upgraded bios and ME twice since I got the new motherboard, no difference in crashes.
Drivers are updated, I’ve also upgraded firmware on harddrives

Parts:
ASUS ROG MAXIMUS Z790 HERO
ASUS ROG STRIX 1000W Gold Aura Edition  
ASUS TUF 4090
14900KF
Corsair Dominator Platinum RGB DDR5 7200MHz 32GB

OS harddrive is a Samsung 990 2tb

Hi, Enrez.

As I carefully looked into the issue, please be informed that if the error: "SYSTEM_THREAD_EXCEPTION_NOT_HANDLED" appears, a Startup Repair is required in most cases.

This error appears especially in Windows® 8 and Windows® 10 due to incorrectly configured, old, or corrupted device drivers. A Startup Repair is required to resolve the issue in most of the cases. We kindly recommend contacting the operating system provider for assistance.
