Only problem I've heard w/ 655 mobos and Corsair is the fact that Corsair tends to use overaggressive timings for these boards when running them by SPD in DC mode. So, pop one stick in first, tell the BIOS to run it at relaxed timings, and then put the other stick in to use dual channel mode.
There could be other problems, I'm not sure.. that one was pretty big at asusboards.com a while ago for a few 655 boards.
