Weird behaviour of Xfx 6900xt in Cyberpunk2077

Hi guys,
I just made myself an Account here, just because I can't find a solution for my problem.

I try to tell about my problem in a short time:

I can play Cyberpunk well for around 10 minutes, sometimes 2 hours and then my pc crashes and goes into bootloop, until I shut it down, wait some time and restart it. So far I only have this problem in Cyberpunk.

I updated all my drivers, including Chipset, Gpu and so on and even cleaned my drivers using DDU. Even my Bios is up to date.
At some point I bent a capacitor near my Pcie slot in which my Gpu is installed, but replaced the capacitor and it just worked fine.

My hardware is as following:

Asus Strix X570-F Gaming
Amd Ryzen 7 5800x
16Gb Patriot Viper @3600mhz Cl18 (maybe 17)
Xfx 6900xt Merc 319
BeQuiet Pure Power 12M 1000W

I swapped out my Psu, because I had an Evga Nex750b with 750 watt before and thought I don't have enough power. I did not daisychain my Powercables and use a single cable for each plug on my Gpu.

I also lowered my Ram speed down to 3200Mhz and Increased my Soc Voltage by 0.05v to have a lil bit more stable ram controller, since that was a suggestion from another forum, that the 6900xt doesn't like Xmp and slight unstable ram. 

When I undervolt my Gpu, or increase my Power Target or change my Fancurve my settings reset after some time of working properly with a crash. If I run everything on standard I still get the crashes.

I tried so much stuff, without any great success. Sadly I don't have any warranties, since I bought my Gpu used and my Mainboard is "too" old now.

Maybe you Guys have an Idea. Tell me if you need more information

It now happened with Red Dead Redemption 2.
