This isn't directly related to BIOS but rather drift in the IMC sensing mechanism during POST. The further outside specification (beyond officially supported memory speeds) you push the more drift the mechanism can be subject to. Manual settings are advised at speeds over DDR3-1600 if required (you can calculate approximate RTL, send me a PM if you don't have the calc).

Are you referring to:
Read in ns = RTL * (1000/Uncore) ?

I was never sure how to use this since it has two missing values that I don't know... How do I get the base RTL(so i can calculate the base read time in ns?) Set my memory to its XMP and see what BIOS selects?

Thanks!
