NEMIX 16GB DDR4 2666 ECC SODIMM

This NEMIX RAM module provides 16GB of DDR4 2666 memory in a 260-pin SODIMM form factor. It operates at 1.2V with a CAS latency of CL19 and features a 2Rx8 rank configuration using major OEM chips.

Workstations and NAS needing ECC SODIMMs

It suits systems that require unbuffered ECC memory for data integrity, such as compatible Samsung workstations or NAS devices. Builders needing non-ECC modules, registered DIMMs, or higher-speed DDR4 should look elsewhere.

The DDR4 2666 ECC unbuffered specification

This single specification decides compatibility: the motherboard must support DDR4 2666 unbuffered ECC SODIMMs at 1.2V. Without that exact support, the module will not function correctly.

Questions about this item

Does my system need an open 260-pin DDR4 SODIMM slot to install this 16GB module?

Yes, the module uses the 260-pin DDR4 SODIMM form factor and requires a matching unbuffered ECC slot on the motherboard.

Can this 2666MHz CL19 ECC SODIMM run alongside slower DDR4 modules already in my NAS?

The memory will operate at the speed of the slowest installed module, so mixing with slower DDR4 ECC SODIMMs is possible but reduces overall bandwidth.

How can I confirm the 16GB 2Rx8 ECC module is detected and error-correction is active after installation?

Check the BIOS or system firmware for the full 16GB capacity, 2666MHz speed, and ECC status showing enabled or active.
