I have the same issue with an MBP Early-2011. The LocigBoard had been changed some months ago, and since some weeks I have that flickering as well, it gets worse and worse. @gary lewis & oldturkey03: I found some picture of the possibly related Philips head screw mentioned in gary's post. Have a look here: https://discussions.apple.com/message/19... is that the mentioned screw?
There seems to be a possibility to upgrade the mid-2012 MBP to 32GB Ram, there’s a thread on this on macrumours, but still nobody has confirmed it works and which modules to use.
Crucial SO-DIMM Kit 32GB, DDR3L-1600, CL11 (CT2KIT204864BF160B) might work - did anybody try this yet and can confirm any 32GB MBP9,1 is possible?
