Apple iMac DDR3 SODIMM kit

This NEMIX RAM kit supplies 8 GB of DDR3 1600 memory in two 4 GB modules built to the 204-pin SODIMM form factor. The sticks run at 1.35 V with CL11 latency and use unbuffered non-ECC chips sourced from major OEM suppliers. They are validated for Apple iMac models released between late 2012 and mid 2015.

Owners of compatible iMacs wanting

The dual-rank 2Rx8 organisation matches the factory specification for these all-in-one desktops. Users who need ECC error correction, registered modules, higher capacities per slot, or memory for Windows laptops, newer Macs or PC motherboards should look at other products.

Ready-to-install matched pair

The kit delivers two modules tested together so they operate in dual-channel mode without further configuration. No heat spreaders are included, keeping the low-profile height required by the iMac's internal slot spacing. No software or drivers are bundled.

Questions about this item

Which iMac models accept this 204‑pin DDR3 SODIMM kit?

The kit is validated for Apple iMac models released from late 2012 through mid 2015.

Can I mix these 1.35 V modules with the original 1.5 V memory already in my iMac?

Yes — the memory controller will run both kits at the lower 1.35 V, so the original sticks stay compatible.

How do I confirm the CL11 1600 MHz modules are recognised at full speed after install?

Open About This Mac → System Report → Memory and verify each slot shows 4 GB DDR3 at 1600 MHz.
