I can't figure out what the 'FSB Strap to NB' option is supposed to do. When set non-Auto it would seem to force a certain divider where Auto would calculate one from FSB and DRAM clock settings. But if that's true then 'FSB Freq', 'Strap', and 'DRAM Freq' should be mutually exclusive. You could set two of the three, but not all three - at least not to mutually exclusive values.

What am I missing?
