What am I missing?
All it does is limit the memory ratios you can use, and possibly loosens some of the subtimings that are still on auto.

In the olden days of yester year (well like two years ago), the strap settings used to control tRD before anyone knew what tRD was. Now it doesn't do jack on mobos with manual tRD control.
