Post your memoriez speeds https://www.intel.com/content/www/us/en/download/736633/intel-memory-latency-checker-intel-mlc.html *download and open with winrar, 7zip etc, then in windows folder and run MLC as admin there is a gui for it too, but it doesn't show all the detail https://github.com/FarisR99/IMLCGui e.g.
What memory is that? Can you post V3.9a too, I saw now in v3.10 they changed latency and it shows higher. I use to get 42.5ns, now 60ns.
Here is the MLC 3.9 In use are 2x8GB G.Skill 7600 DDR5, on a Gigabyte Aorus Master Z790 Mainboard and Intel 13900k CPU.
