    I bought this memory last month and about a few weeks later I started getting problems.

    It started out that my mac would just crash (fubar graphics and then the "reebot your mac by holding the powerbutton msg")... Sometimes it wouldn't come right back unless I re-seated the DIMMS but as of the last week my mac would sometimes not come back from sleep and now I can only get my macbook pro to run if I remove one of the DIMMS leaving me with just 4GB. It doesnt matter which DIMM I use, both of them work on their own. But as soon as I combine the two it does not boot. I have no way to test the memory since I can't even bootup with the pair installed now. Kinda sucks since I just gave my old 2x2GB DIMMS to a coworker. I'm thinking I need to do an RMA with Gskill and that's going to be a pain in the ass I bet.

    FWIW I have a 13" MBP MacBookPro5,5 (Mid-2009).

    I said I can't test the memory fully because it doesnt boot up with both DIMMS in...I can only use 1 DIMM at a time
