I've read confusing reports as to whether or not 32GB of ram is usable in a 2012 cMPB. Most information I can find are from people telling other people they were crazy in 2012 for wanting such an amount of ram. Fast forward to the present and 32GB isn't unreasonable at all. Kits float around on ebay all the time, but I have no idea if they'd work in my machine. Would it work?
