    I just upgraded my MBP from 2gb of RAM to 4gb and now I am getting errors that I have to hold the power button and restart. the RAM I put in is Mushkin 2gb sticks, DDR3, 1067Mhz laptop RAM which matches the RAM that the MBP came with, I bought a pack with 2 of the 2gb sticks in it to total 4gb when in the system.

    The upgrade went smooth, I tried with one of the sticks, one old and ran fine, and tried with both of the new ones and it ran fine also. but after a while I have been getting these random restart messages.

    After I installed the RAM I ran a memory test and it came back all positive.

    any one have an idea as to what is wrong? Thanks in advance for the help!

    It sounds like bad RAM to me. I would but the original 2 GB back in and see if it happens again. If it doesn't you have dodge RAM.

    Sometimes even if the RAM is bad, it will show up as ok in tests and then randomly has a problem.
