AFAIK, QVLs are recommendations. But still, can't you look for alternatives? I'd rather you use sticks that are fully compatible with the mobo. Obviously, the QVL's a good guide in this regard.
I've had great success with Gskill ram compatibility. The one time I had to RMA, it was older ddr400, the replacement came back to me in 6 days! And not a cross ship. They will continue to get my business.
