    After I installed 16GB DDR3-1600, the MBPro now much faster but i've been testing it using CAD, 3D renderers and games - and it reboots when doing higher level computations.

    I pulled out the new RAM and plugged in my original RAM for testing, and works fine.

    I am using a MacBookPro8,2 Early 2011 15" Core i7 (I7-2635QM) with a pair of F3-1600C10D-16GSQ.

    Did I get bad RAM?

    Try Memtest and refund if something is wrong.

    Otherwise, reset the PRAM and SMC

    The F3-1600C10D-16GSQ kit works on a MacBookPro8,1 Early 2011 13" Core i7 (I7-2620M)
    [​IMG]

    I ran memtest but 12 gigs was only detected.

    Mac OS X 10.8.2 (12C60) running in multiuser mode
    Memory Page Size: 4096
    System has 8 Intel core(s) with SSE
    Requested memory: 12198MB (12790575104 bytes)
    Available memory: 12198MB (12790575104 bytes)
    Allocated memory: 12198MB (12790575104 bytes) at local address 0x0000000101000000
    Attempting memory lock... locked successfully
    Partitioning memory into 2 comparison buffers...
    Buffer A: 6099MB (6395287552 bytes) starts at local address 0x0000000101000000
    Buffer B: 6099MB (6395287552 bytes) starts at local address 0x000000027e305800

    Running 2 test sequences... (CTRL-C to quit)

    Test sequence 1 of 2:

    Running tests on full 12198MB region...
    Stuck Address : testing 7 of 16

    FAILURE! Data mismatch at local address 0x000000035be63818

    Linear PRN : ok

    Block Sequential : ok
    Checkerboard : ok
    Bit Spread : ok
    Bit Flip : setting 187 of 512

    Then it failed. Could it be a mis-seat? From what I understand if one of the modules is unseated - it should read 8 gigs only. Since 12 was read - one side of the RAM chips on one board could be defective?

    Sorry for the late reply, but it sounds that you need to RMA :(

    If you believe it was a mis-seat, you can switch up the RAM sticks and run MemTest again. However, it looks like one of your sticks is defective, so I'd just contact the RAM maker and RMA the memory. You can even show them your MemTest results so that they know what's wrong with the RAM (helpful for quality control and future RAM).

    Not to mention proof that the product is truly defective so there should be no trouble getting an RMA.
