DRAM calculator for AMD Zen 3

[cocjh1]

I downloaded the DRAM calculator but noticed it has not been updated for Zen 3:

Is Zen 2 a good starting point, or are there any alternatives?

I'm running XMP profile (stable), so will spending the time manually tuning the memory return significant speed benefits beyond what XMP has given?
