iMac 27-inch, Late 2012- Problem with 3 b4 slots for RAM
Hello. My Imac (27-inch, Late 2012) has the original memory (2x4GB Elpida) in slots 1 and 2. When trying to install in slots 1+3, 1+4, 2+3, 2+4 it beeps three times and the Mac does not start. Replacing the original memory in slots 1+2 with new memory (2x8GB) is successful. Can not add memory to slots 3 and 4 (old memory or new). Please advise where to look for the problem.

As you can see here your system can support 32GB!
But you need the correct SO-DIMMs
