Corsair would likely work fine, long as you get it in a pack with matched sticks. Something that will definitely work (or should), is G.Skill Ripjaws 4 Series (blue colored). Check it on pcpartpicker, also u can check the qvl list from asrock. 2x8Gb quad core stick pack, or 4x4Gb, should work fine. It's really strange that people have had problems using the red colored version of this same ram on the Extreme4 and up boards, though it works fine on the Fatality series(which is themed red).
