According to AMD[1] and ASUS[2]  docs : [quote] DDR3 1600 can only be
supported with AMD Opteron™ 6300/6200 series processor [/quote]
so, I should be fine.

I didn't knew exactly what king of RAM to chose (CL, Voltage, Rank,
etc.) in order to have them running in quad channel, because those
recommended by ASUS here [3] are ether very expensive or unavailable.
But if you say that if I choose one of these [4] [5] it will work in
quad channel, then it's ok.


Thanks a lot!

BogDan.
