My new 16GB Corsair RAM arrived today... and, with a memory test, it failed during the first run (I always do a burn-in of 5 runs before doing anything productive... data corruption is not cool...) The previous time I attemped 16GB was also with Corsair, "Mac Certified" RAM, and it eventually failed the burn-in test during the third loop. Replacing with the original Kingston RAM and re-testing showed the RAM working fully. If you've attempted 16GB, and ran a battery of stress/burn-in tests and found all the RAM to pass, or even if not, would you chime in? I doubt my MBP is faulty, but anything's possible... Thanks!
