System-Specific DDR4 Kit

This A-Tech kit delivers 32 GB of DDR4 2400 memory in four 8 GB SODIMM modules built for the 27-inch iMac from Mid 2017. It matches the Apple order numbers MNE92LL/A, MNEA2LL/A and MNED2LL/A and the model identifier iMac18,3.

260-Pin SO-DIMM Upgrade

Each module installs directly into the iMac’s four SO-DIMM slots using the standard 260-pin DDR4 interface at 1.20 V. The unbuffered, non-ECC 1Rx8 design requires no heat spreader and leaves the existing memory architecture untouched.

For Mid 2017 iMac Owners

This kit suits users who want the full 32 GB capacity supported by the Mid 2017 27-inch iMac and who can populate all four slots. Builders working with any other Mac model, a different iMac year, or a system that needs ECC or registered memory should look elsewhere.

Questions about this item

Does the DDR4 2400 SODIMM hit thermal limits during sustained workloads on a 27-inch 2017 iMac?

These modules run at the standard 1.20 V and have no heat spreader; the iMac’s internal airflow manages temperature during extended use.

How much fan noise or extra heat appears when all four slots are filled and the system runs all day?

Unbuffered 1Rx8 DDR4 at 1.20 V adds minimal thermal load; the iMac’s cooling curve stays unchanged under typical all-day workloads.

What must the Mac already have for this 4 x 8 GB kit to be recognised?

A 27-inch Mid 2017 iMac (model A1419, EMC 3070, model ID iMac18,3) with four empty SO-DIMM slots.
