Reword "The DIMM max tCKmin is" to "The combined tCKmin is". It means the max
tCKmin across all DIMMs on the same controller.

That still needs some work, IMHO.  I think you might need the word
"which" before "doesn't".  However, even with that, it's not clear
what's wrong.  Where does the bad value of "mclk_ps" come from?

It happens when the actually DDR clock is faster than the slowest DIMM
can support.

Did you guys agree on wording?  Is the patch ok or needs changing?

I haven't seen an updated patch from York.  I'd like to see the addition of text
like, "It happens when the actually DDR clock is faster than the slowest DIMM
can support."  People need to know what to fix, not just what's wrong.

Also, %d is for signed integers, not unsigned.

I will update the patch according to Timur's suggestion.
