I have 2 Questions.

  1. I had another board and a 7800x3d, did an RAM OC and it was 100% stable. now i copy pasted everything and its 100% stable (kahru 12h, y-crunher FFTv4, N63, VT3 12h, occt stability certificate platunum) all fine but the RAM hase worse benchmark, this must mean the cpu/memory controler performes worse? Will probably try to thighten timings again and see if i can go lower on 9800x3d.
  2. Any tips to get 6400 error free? tried playing with the voltage but could not get it better, kharu errors within 5min. i guess the impedance settings should be important here but honestly i have a very hard time in finding much information about them and a usueful base to start and strategie, there are just too many possible combinations. anything that could be helpful to understand them would ber very nice.
