I was not going to OC, just use the speeds available in the BIOS for the
memory clock rate. So, if I have PC-3200 it would be set to that or PC-4200
for that ram. I would think Asus was smart enough that this would not OC the
SATA portion, just bump up the memory clock rate for faster ram (or, to
intentionally OC your ram -which I will not do).
