NEMIX RAM
A 32 GB DDR4 2666 MHz CL19 SODIMM module at 1.2 V for Mac Mini 2018 upgrades
This NEMIX RAM module delivers 32 GB of DDR4 2666 MHz memory in a 260-pin SODIMM form factor. It operates at 1.2 V with CL19 latency and a 2Rx8 rank configuration using major OEM DRAM chips. The non-ECC unbuffered design matches the factory specification for the Apple Mac Mini 2018 (Macmini8,1).
Buyers who require ECC error correction or registered buffering should select a different module. The single 32 GB stick fills one slot; systems needing matched pairs or lower-density modules for dual-channel flexibility are not addressed by this part.
The 2Rx8 organisation at 32 GB per module is the decisive specification. Apple's Mac Mini 2018 memory controller accepts this rank and density combination, so the module installs without compatibility issues. Other densities or rank layouts may not be recognised by the firmware.
