AM5 Asrock X670e Pro RS - crashes

I've only game crashes and blue screens with my Asrock X670e Pro RS.



My system:
CPU: AMD Ryzen 5 7600X
RAM: 2 * G Skill F5-6000J4040F16G 16 GB DDR5-4800 DDR5 SDRAM
Mainboard: ASRock X670E Pro RS
power supply: Corsair RM850
graphic card: NVIDIA GeForce RTX 3080 (10 GB)
HDD / SSD: WDS500G1XHE-00AFY0 (500 GB, PCI-E 4.0 x4)


Here's what I tried:
-reinstalled Windows
-bought new memory
-bought a new cpu (also the 7600x)
-tried bios update 1.07 and 1.11(AS beta 06)
-cmos reset
-RAM with and without xmp
-windows power settings
-[Global C-state Control] to [Disable] in the bios

What I noticed was that when I set the voltage to 1.22V with a clock of 5000MHz, that it runs better in some games. But crashes still occur.

I run even better when I deactivate PBO (Precision Boost Overdrive) and CBS (Core Performance Boost) in the bios.
But unfortunately, that's not a real solution either, since you end up losing quite a bit of performance, then you could have just bought something cheaper.

I think ASrock has real problems with the motherboards

not enough info here to say anything but i do have the same motherboard with 7950x with 2 x 32GB. I have "slower" micron DDR5 5200 but it is running at 5200 and have no issues etc. if i push PBO/OC bit too much, it sure does crash but otherwise no problems with my setup.

play with your RAM speed, timing etc to make sure all is stable.

jop driver are all installed

I have run the test twice.
Finally, I had tried other memory, which also did not work.
