NEMIX RAM 64GB Kit for 2019 iMac 27" & 2018 Mac Mini

This kit provides 64GB of DDR4 2666 memory in two 32GB SODIMM modules. It is built for Apple iMac19,1 and Macmini8,1 systems that accept 260-pin PC4-21300 unbuffered non-ECC RAM. The modules run at 1.2V with CL19 latency and use major OEM chips from Samsung, Micron or Hynix.

Ideal for creative pros upgrading 2019 iMac 27"

Editors, developers and multitaskers who hit the factory memory ceiling will gain headroom for large timelines, virtual machines and heavy browser workloads. Systems already at 64GB, users needing ECC protection or machines outside the two listed Apple models should look elsewhere.

64GB total capacity with two 32GB sticks

The dual-rank 2Rx8 layout fills both slots on the target iMac and Mac Mini, delivering the maximum supported memory for those platforms. It comfortably handles 4K video timelines, multi-VM setups and large dataset work. Workloads that demand more than 64GB or require registered ECC modules exceed what this kit can provide.

Questions about this item

What Mac models must I own for this 260-pin DDR4 SODIMM kit to be compatible?

This kit is validated for the 2019 iMac 27-inch Retina 5K (iMac19,1) and the 2018 Mac Mini (Macmini8,1) that accept DDR4 2666 non-ECC unbuffered SODIMMs.

Will the CL19 2Rx8 modules run stably alongside any original Apple memory I keep installed?

Yes, the modules operate at the standard 1.20 V DDR4 2666 speed with CL19 timing, so they will down-clock automatically to match existing Apple memory without voltage or timing conflicts.

How can I confirm the full 64 GB is recognised and running at 2666 MHz after installation?

Open About This Mac or System Report on the iMac19,1 or Macmini8,1; it will show 64 GB total across two 32 GB slots at 2666 MHz DDR4 with CL19 latency.
