I was planning on buying G.Skill Ripjaws X 4GB, but I read online that they aren't really friendly with the Extreme4, on NCIX CA, the 8GB Corsair Vengeance RAM is currently $65, would that work? Or what is another good and compatible RAM kit for my specific mobo? http://ncix.ca/products/?sku=59431&vpn=CMZ8GX3M2A1600C9B&manufacture=Corsair&promoid=1190
