Apple iMac Late 2015 memory kit

This 64 GB kit contains four 16 GB DDR3L SODIMM modules built for the 27-inch iMac (Late 2015). It runs at 1866 MHz with a low 1.35 V voltage and uses unbuffered, non-ECC chips in a 204-pin form factor.

Owners of the specified iMac models

The kit matches Apple order numbers MK462LL/A, MK472LL/A and MK482LL/A as well as model identifier iMac17,1. It will not suit users with other Mac models, desktop DIMM slots or systems that require registered or ECC memory.

Four-module 64 GB capacity

Filling all four SODIMM slots with 16 GB modules delivers the maximum 64 GB supported by this iMac. Buyers needing less memory or a different module count should choose a smaller kit.

商品問答

Will the 1.35 V DDR3L modules run cooler and draw less power than standard 1.5 V DDR3 when the iMac is under load all day?

Yes, the 1.35 V DDR3L voltage reduces power draw and heat output compared with standard 1.5 V DDR3, helping the iMac stay cooler during extended workloads.

Does the iMac (Late 2015) need any firmware update or special tools before I install these four 16 GB SODIMMs?

No firmware update or special tools are required; the 204-pin DDR3L 1866 MHz modules are a direct drop-in upgrade for the iMac17,1 (A1419, EMC 2834).

Can I keep the original Apple memory and add this 64 GB kit alongside it in the four slots?

The Late 2015 27-inch iMac has only four SODIMM slots, so the 4 x 16 GB kit fills every slot and leaves no room for the original modules.
