Best 1600 ddr3 240pin ram?

I've read a lot of good things about the Corsair Vengeance so they're up there recommendation-wise. Mind you, depending on your heatsink, the heat spreaders on the Vengeance might cause problems (assuming you populate all 4 dimms). I personally use G.Skill 1600 (2x4GB) and Mushkin 1600 (2x2GB) and they've worked flawlessly for me. So, I'd suggest you buy from either Mushkin, G.Skill, Corsair, and Kingston HyperX. Also, I'd suggest getting a low CAS Latency kit, something like a CL8 1.5 volt kit (which is what I have) but CL9 is also good. Getting a 2x4GB kit would be a smart idea cause itwould leave you 2 dimm slots open for future expansion.

Here are some product links (in no particular order) (these are all 2x4GB kits):
Mushkin: http://www.newegg.com/Product/Prod [...] 6820226295 (CL8)
Corsair: http://www.newegg.com/Product/Prod [...] 6820233147 (CL8)
G.Skill: http://www.newegg.com/Product/Prod [...] 6820231445 (CL8)
Kingston HyperX: http://www.newegg.com/Product/Prod [...] 6820104255 (CL9)

I can personally vouch for the Mushkin's and the G.Skill's cause those are the exact one's I'm currently running. As for the HyperX's and the Corsair's, I've heard nothing but good things about them. In the end, it comes down to your preference in looks/style, how it might/might not conflict with your heatsink, and how much you're willing to spend.
