I was wondering about the AHCI issue with the newer AMD boards, too. Is there any update on that as I can't find any more info on it and I haven't found much either (nothing specific or to answer my questions). I think there is something related to the SATA burst rate being poor?
Thanks for your reply, however!
I'm looking at a MSI 785G board anyway, though but it would be nice to find some info on the AHCI issue explained and figure out which RAM type I should go with (which really makes a difference in which boards one can consider).
