Hynix original 16GB (2 x 8GB), 204-pin SODIMM, DDR3 PC3L-12800, 1600MHz memory module (electronics)
I can deliver my iMac 5k with 16 GB RAM and then to buy this upgrade kit and thus upgraded the RAM to 32 GB. There are exactly the same storage latch as genuine Apple installed (the L version). Therefore fits properly and works right away!
