Continuously getting Event 18 (Cache Hierarchy) errors with my Ryzen 9 5950x / RX 7800 XT

Hey folks,

 

Update: I lied I guess. even with PBO off, it's started black screen crashing whenever I try to load into a game now. The only difference this time, is that the Event 18 errors are now showing APIC ID: 23 and 13 instead of 28 and 7. This...is frustrating.

 

As a further update: I swapped my old RTX 3060 in, still getting the Event 18 errors and crashing into a reboot.

 

First post so I'll do my best to make sure to include all of the relevant information because I'm honestly at my wits end here.

I just updated my hardware from the Ryzen 7 CPU series and an RTX3060, as well as my RAM from 32GB to 64GB (new kit).

 

Hardware specs first:

MOBO - ASUS ROG STRIX x570-e Gaming w/ wifi II

CPU - Ryzen 9 5950x

GPU - GIGABYTE Radeon RX 7800 XT Gaming OC 16GB

RAM - G.SKILL Trident Z RGB Series (Intel XMP) DDR4 64GB (2x32GB) 3200 MT/s (I also verified this ram is on the QVL for my mobo) (Also slotted into A2 / B2)

Cooler - DeepCool AK500

PSU - Corsair RMX Series RM750x. 750 watt, 80+ Gold Certified

Storage - Western Digital SN850 NVME M.2 2280 1 TB

- WD Green SSD 240gb

- Seagate BarraCuda 1TB HDD internal drive (I don't actually use this one just haven't unplugged it yet)

PartsPicker shows wattage sub 600w with the above.

 

Issue: After slotting all the new hardware, I initially tried to play Star Citizen (I know) and Stalker 2, both games produce a black screen crash and reboots my PC. Event viewer is showing the following two errors:

A fatal hardware error has occurred.

Initial fix attempts:

- BIOS update for the Ryzen 9 5950x (this was done prior to installing the CPU

- Clean windows 11 install (did not keep files)

- DDU'd previous NVIDIA drivers from the old card

- Reinstalled the appropriate AMD drivers from the Adrenalin App

 

Reviewed the performance monitor within Adrenalin as I would attempt to run the games, CPU temps seemed stable, wouldn't go above 55c before crashing.

None of the above worked to prevent the crashing or fatal errors, however, after disabling PBO in the BIOS (no other settings changed, all default), the games no longer crash. So my question is basically the title, does my hardware just not support PBO and everything is fine so long as that's off, or is there something wrong with the CPU?

 

Thank you in advance for any help, this is my first time upgrading the only PC I've built, so I'm not super technical with all of this.
