No. But I would list your board brand and model number. Chances are it will run several brands of ram. Frys has some corsair 2x4 gb of 1333 for only $25 after rebate in today's ad. I've used about 4-5 different brands of ddr3, and had no problems so far. CL 9 is a little slower and a pretty standard spec for ddr3, so it should work fine. Crucial makes good ram and it's guaranteed to work if you order directly from their website, but you'll pay more. I go for rebates, and have been lucky so far.
