This is really just something I have been curious about. I know XMP is an Intel specification, and how the platforms handle tRC or tRAS is a bit different.
When the ram is tested on motherboards for the QVL, are these timings set manually or are the motherboard automatic values used? For example, I have the F4-3600C14D-32GVK set, and the XMP values of those timings seem to be tRC 50, tRRDS 4, tRRDL 9, and tFAW 44. At least if tools like AIDA or thaiphoon are reporting those correctly.
But the various AM4 motherboards I have owned seem to calculate those timings based on the base SPD timing, which for this kit works out to tRC 83, tRRDS 6, tRRDL 9, tFAW 38.
Only somewhat related since it just has to do with setting XMP and forgetting it, are the termination values (ProcODT, RTT) used the motherboard automatic values?
Thanks in advance!
