Hi everyone, I've replaced my late 2011 MacBook Pro's RAM-memory last week and I keep getting kernel panics on random moments: when opening Photoshop, when shutting down the computer, when doing basic web browsing... I replaced the stock 4 GB sticks with 8 GB Corsair 1333 MHz DDR3 Mac-memory (240 pin) and I even got a kernel panic during memtest. Now, I really need to use my computer tomorrow at school and I can't afford losing time and data so I was wondering: should I try changing the modules like putting the bottom one on top and vice versa, or should I just install the stock RAM modules for tomorrow but "lose" 4 GB? I sort of need the extra RAM... I'd really appreciate a quick answer, so thanks in advance! EDIT: I also tried to reinstall OS X - didn't help. The 10.7.4-update didn't help either.
