Certainly, there's a part of me that likes the confidence of Crucial's guaranteed compatibility.

Do I need to worry about voltage or latency or anything? Or will any DDR3 SDRAM 240-pin work?

EDIT: Hmmm, now I'm seeing that you can get 10600, 10660, 10666, etc... in speeds. I think I'll end up with Crucial where they guarantee that compatibility!!

Any difference between, say, 12800 and 1600 speed if I'm not gaming?
