Kernel panics related to RAM?

[Nilscollection]

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.

You could try switching them, it's also possible simply pulling and reseating will work.

That said, more frequently it's a bad DIMM. Consider switching back to your old ram if uptime is critical.

is this what you used for MemTest? if its crashing during memtest than i would highly recomend puting your original ram back in to see if the kernal panics stop

That's what I used, yes. I'll put in the original RAM for tomorrow and I'll test the other set during the weekend.

Could failing RAM also be noticed by the Apple Hardware Test?
