Product Identity

This is an 8 GB DDR4 SO-DIMM built for 2017 iMac models with 21.5-inch or 27-inch Retina and non-Retina displays. It targets owners of those specific Apple desktops who want a single 8 GB module to add memory capacity.

Deciding Specification

The module runs at DDR4 2400 with CL17 latency and 1.20 V on a 260-pin unbuffered, non-ECC layout. That exact speed, timing and voltage combination is what makes it compatible with the listed iMac 18,1, 18,2 and 18,3 systems.

Thermals and Power

Standard DDR4 1.20 V operation keeps power draw low and heat output minimal inside the compact iMac chassis. No active cooling is required and the module runs silently under normal workloads.
