Compatible iMac memory kit
This 16 GB kit contains two 8 GB DDR3 SO-DIMM modules rated at 1333 MHz. It is built for the Apple iMac 21.5-inch Mid-2011 model with a 2.7 GHz Core i5 processor. The unbuffered, non-ECC sticks run at 1.5 V with CL9 timings.
Upgrading from the factory 4 GB
The iMac shipped with 4 GB across two slots; this kit fills all four sockets and reaches the 16 GB ceiling for this configuration. The jump is worthwhile when macOS, creative apps or virtual machines regularly exhaust the original memory and cause swapping.
Check your exact model identifier
Confirm the machine shows iMac12,1 and part number MC812LL/A in About This Mac before ordering. The system supports a maximum of 32 GB across four slots, so this 16 GB kit leaves room for a future matched pair if needed.

Spørsmål om denne varen
Does this 204-pin DDR3 SO-DIMM kit fit the four memory slots in the 21.5-inch Mid-2011 iMac?
Yes. The kit provides two 8 GB modules for the four SO-DIMM slots in the 21.5-inch Mid-2011 iMac, bringing total memory to 16 GB against a 32 GB maximum.
What is the correct way to seat these unbuffered CL9 modules so the iMac recognises the full 16 GB?
Power off and unplug the iMac, remove the memory access door, insert each module at a slight angle until the gold contacts are hidden, then press down firmly until both side clips click.
When should the two 8 GB sticks be replaced if the iMac starts showing memory errors?
Replace them if Apple Diagnostics reports a memory failure or the system kernel-panics repeatedly; the modules carry a limited lifetime warranty from Computer Memory Solutions.
