Installed 32gb RAM but only 16gb usable
I have a 27" iMac, late 2013 model. I'm running Windows 7 Home Premium 64 bit on it via BootCamp.
I ordered (4) 8GB RAM from Crucial.com and installed them myself.
Now iMac says that it sees the 32GB but only 16GB is usable. I've already confirmed on the Apple Support site that this computer can in fact be upgraded to 32GB. What am I doing wrong or haven't done yet??
