Anyone heard of any issues with RIIE and the CAS 9 DDR3-2000 G.Skill Rijpaws?

I've got 2 sets of these that I'll be cannibalizing: http://www.newegg.com/Product/Produc...81&Tpk=ripjaws

Figure if they work fine with 6GB I'll snag another 4GB set for 12GB total (same as getting 2 triple channel kits I guess )

I had them for P55 but switching to X58 for my 24/7 rig.
