Random PC Abrupt Shutdown

[deadguyx]

So i recently built a PC with the following specs:

CPU: AMD Ryzen 5 7600X
Motherboard: MSI - AM5 B650-P Pro Wifi
RAM: G.Skill Flare X5 32GB (2x16GB) DDR5 6000MHz CL36 EXPO (F5-6000J3636F16GX2-FX5)
PSU: Seasonic Focus 850W 80 Plus Gold Modular
 

After some days the PC started crashing while playing games. I ruled out PSU issues(by swapping with other PSU, altough the PSU was only 650W, could also crash due to the lack of power?), and eventually swapped out this RAM and used a 2x8GB RAM sticks, the issues stopped and the swapped out RAM caused other PC to crash(A reason for the RAM causing the other PC to crash might be because its not listed in the compatibility list of the MOBO. So maybe that is not a good test.). The only spec that is the same between PC's is the CPU but this CPU should work with this RAM without an issue. With further testing i found out that if ran the PC with only one stick of the 2x16GB RAM it works without issues aswell. After seeing this i sent my RAM to warranty, in wich they didn't find any issue with it, but still got my RAM replaced just in case.After the new RAM arrived, i installed it, and start having the same issues again.Could something cause my PC to only run with 16gb? I can't think of anything else.
I tried using EXPO, and without EXPO by lowering the frequency, but so far i even have crashes running with only 4400MHz.

Any of this makes sense and i really don't know what could be happenning. Anyone got an idea?

Thanks in advance.

Check event viewer for crash logs around the time of the crashes, might help us determine the issue

I mean, it almost sounds as if your mobo isn't running up to spec. Are you sure you are running the memory in the correct configurations per your mobo manual?

I don't see nothing that could indicate what is the problem

I think it is. At least the RAM's are EXPO ready and it crashed even when i used the EXPO profile. Apart from that i just turned it off and set the frequency manually
