Since upgrading to 8GB of Corsair RAM, my MacBook Pro occasionally crashes. Has anyone seen a crash like this? It's pretty nasty; the speakers get all fuzzy and the whole system goes down. It restarts completely normally. http://imgur.com/1l9QLbt I'm wondering if either of the sticks are damaged (both memtest and AHT report no errors) or if they just aren't seated correctly. Naturally, out of AppleCare.
