NEMIX RAM 16GB DDR4 ECC SODIMM kit

This kit provides 16GB of DDR4 ECC unbuffered memory in two 8GB modules. It runs at 2666 MT/s with a CL19 latency and operates at 1.20 V. The 260-pin SODIMM form factor is built for the Synology DiskStation DS923+ NAS.

Suited for DS923+ owners adding ECC capacity

The modules are validated for the DS923+ and deliver error-correcting reliability for file services and virtualization. Systems that require registered DIMMs, non-ECC memory or a different pin count cannot use this kit.

Deciding specification: 2666 MT/s DDR4 ECC SODIMM

The DS923+ memory controller expects DDR4 2666 ECC unbuffered SODIMMs; matching that speed, voltage and error-correction type determines whether the upgrade will be accepted by the NAS.

Questions about this item

Should I choose the 16GB kit or a different capacity?

This kit provides 16GB total using two 8GB modules. It matches the DS923+ dual-channel layout for maximum bandwidth.

What does DDR4 2666 mean for my NAS performance?

The modules run at 2666 MT/s with CL19 latency, delivering PC4-21300 bandwidth. The Synology DS923+ memory controller will operate them at this rated speed.

Does the 260-pin ECC SODIMM interface limit speed or capacity?

The 260-pin DDR4 ECC SODIMM form factor fits the DS923+ slots directly. It supports the kit's 2666 MT/s rating and 16GB total capacity without downclocking.
