So I got my new system all running, yaya! Install a few programs to check everything is all good. I get around to SIW and notice that my RAM is running at 1333. I specifically remember ordering 1600, so I go to check the box, Invoice, and the sticker on the RAM to confirm its 1600. I go zooming around the net to find some answers, and conclude I need to activate X.M.B in my BIOS. I do so, but still from what I can tell it is running at 1333 instead of its advertised 1600. Whats the deal...?
