As I said, I I have a 5900X with DDR4 micron e-die 32GB dual rank. I actually posted worse timings on zen3 leaderboards at that time. This system is fully stable it is y-crunch 72h stable and tm05 extreme anta 10h stable. Any suggestions to improve timing and disable gear down mode. This system is air cooled but I replaced the paste with PTM which is doing an excellent job also on my GPU (RX 6800XT).
