Found out my Mushkin Stiletto memory doesn't have that capability, hence no XMP in BIOS.
Not sure if it's a great loss or not, but hey, got a good deal on the memory. Thanks for the help though.
You shouldn't need to with that RAM anyway – XMP is designed for making it easier to run it at the manufacture's specs, but outside the official DDR3 specs. That RAM holds to the official specs, hence doesn't need it.
