BRADY_D79 Posted February 8, 2013 Share Posted February 8, 2013 Hi there, I recently got a ram upgrade for Christmas: 16GB 2 x 204-pin SODIMM DDR3 1600 MHz 11-11-11-30 1.35V (Part no. CMSA16GX3M2A1600C11) and when I installed it in my Macbook Pro (mid 2012), the laptop refused to boot up...at first, it wouldn't leave the apple screen, then when I forced a shutdown and reinstalled the two sticks, I got the apple screen, followed by a bunch of jibberish writing with a black background running through the screen. I don't understand, is this not compatible with my Macbook?? The package says "MACMEMORY" next to the Mac logo and specifically says that it's compatible with a Macbook Pro with Intel i7...my stock ram is 4GB of DDR3 1600MHz, so this should theoretically work perfectly fine, right? Can anybody tell me why it doesn't? Link to comment Share on other sites More sharing options...
