So I finally decided to tune my RAM kits and got the following timings, voltages and bios settings.
FCLK is set to 2100 MHz in the first picture but I actually ran the test with 2133 MHz and it seems to be stable, also the image I attached at the end with AIDA64-Extreme is with FCLK 2133 MHz.
For stability I ran 2 hours of Memtest 5 with anta777_extreme profile with max temperatures of 47.8 degrees on the RAM and I also tested 4 hours of gaming in different CPU heavy titles without crashes and no WHEA-Errors monitored with HW-Info64 latest version.
Gear Down Mode is one setting I could disable to get lower latency but I think it will give me more instability.
My pbo offset is -25 all cores and thermals set to motherboard.
What do you think about the voltages and timings, anything I could improve at this point?
I am aiming for tightest timings for gaming while maintaining stability.
Edit: I did the AIDA64-Extreme test in Windows safemode and achieved 60.7 ns. Not really relevant to me since it does not represent a real scenario in daily usage but nice to know anyways
