    I recently did an upgrade to add additional SSD to iMac 27' mid 2010, with all the official cables, bracket, etc.

    everthing worked great.
    but now 1 day later i discovered that my 16GB show up as 8GB!
    after testing every memory slot separately - turns out Upper right memory slot now cant read any RAM (Ram is fine in all other slots). When i start mac with any memory in this slot alone - the screen is black and its a beep with a long pause, then a beep again (having 2 RAM modules in upper row - same thing)..

    I know the slot was working before - since I tried 16GB before SSD upgrade.
    So with all 4 memories it shows up as 8GB. when i remove RAM from this upper right slot - 12GB get registered from the remaining 3 slots.

    After removal of logic board I think, i've heard a tiny loose part and found that loose "connector".
    I just kept it.
    Now I have all the reasons to believe that this connector caused this 1 memory slot to be not working.
    Anybody recognizes what could that be?

    if you could mark on these photos of logic board where to pay a very close attention (obviously somewhere in memory slots).

    Thank you.

    That piece is on the "top" (where the cpu drops into its socket) of the logic board. It resets the SMC when pushed in. Its like a small switch. If memory serves me right, it was labeled SMC RESET in white, printed on logic board.

    Were you able to get warranty since you did the upgrade?
