Hi Dale,

thanks for your info! :)

I think it is called "Auto" with the MSI bios.
When using this, JEDEC timings and a command rate of 2
instead of 1 are choosen for DDR4 (as an example)...which
isn't optimal.

These "Auto" were the reason for better settings.
I think I have to tweak the bios settings by hand...

Cheers!
