Just built my new PC, and almost 2 days suffering with DDR5. Got Apacer Nox 2×32 6200, seems to be Hynix M-dis, cause RFC doesn't go under 500. What can I do to reduce latency?
Testing stability right now with FCLK 2133 and RCD 37, but latency still about 69-70.

Is there anything indicating if the memory is running in 2:1 mode? I noticed on my system that running 6600 memory at 3% faster at 6800 caused a 25% increase in latency. 32 -> 40
Purely as an experiment can you set the memory to the official max speed of 5600 for the AMD Ryzen 5 9600x and check the latency.
I have an even bigger problem with the fact that my 6400 QVL listed memory is only stable at 6000 on an Epyc which apparently is notorious for not really supporting the expo speeds on the QVL.
Are you testing latency in windows safe mode?
