The issue is this though, ram performance will be slower. Now i asked abit to add the NB latency settings into bios also with the hope that the 1333 slowness could be countered by altering the latency, pretty much like you saw on the IC7 boards.
Micron based dimms are more tollerant and give the memory controller an easier time...they will allow 1;1 and above 350fsb easier using the 1067 strap, but they will still top out.
ALL the 975 boards at this time excpet badaxe are using the 1067 strap and not moving to the 1333..this is the reason they are ALL clocking less than 965. 965 is also a better clocking chipset and will clock higher in the strap range than 975 but it does still top out, this is why we see asus using 1333 at 400 and up.
So in short the dimms may limit you a little yes, the nature of the chipset is also limiting you and unavailable bios options.
