Thanks for the input! Reading more and more about it scares me. Some people say they needed to custom tune their setting and others say it worked fine. Just wanted to get a straight answer so I can flawlessly use 2133 g.skill ripjaws x no problem with my mobo
The sticks are not listed as supported (I think), but that's because Asus doesn't have the time to test all the sticks that are available, so they should work. You'll probably have to manually adjust the speed, timings, and voltage in the BIOS, since 2133MHz is listed as "OC" in the specs of the board.
EDIT: It will probably work just fine on first boot, but it might be automatically underclocked.
