Two green DDR4 ECC UDIMM modules without heat spreaders

NEMIX RAM

NEMIX RAM 32GB (2x16GB) DDR4 2400 ECC UDIMM Kit Synology Compatible

SKU CH-73K8-B3M1J

A 32 GB dual-channel DDR4-2400 ECC UDIMM kit with CL17 latency and 1.2 V operation for Synology NAS systems

  • Capacity32GB (2 x 16GB)
  • SpeedDDR4 2400 (PC4 19200)
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • ECC protects data integrity in Synology NAS
  • 32 GB kit expands memory for demanding workloads
  • DDR4 2400 speed matches supported system specs
  • 2 V operation reduces power draw and heat
  • 288-pin UDIMM form factor fits compatible Synology slots

Kit Composition and Target System

This kit provides two 16 GB DDR4 ECC UDIMM modules for a total of 32 GB. It is built for Synology RackStation NAS units that accept unbuffered DDR4 memory. The modules run at 1.20 V with a CAS latency of CL17.

DDR4 2400 Speed and Platform Constraints

The memory operates at DDR4 2400 (PC4-19200) despite a model reference to 2666 MHz. ECC error correction is active only on platforms that support it. Unbuffered design means no register delay, but the platform must accept 2Rx8 organisation.

Physical Build and Daily Handling

Modules use major OEM chips from Samsung, Micron or Hynix without a heat spreader. The 288-pin UDIMM edge connector fits standard DDR4 slots. Low-profile bare PCB eases installation in tight NAS chassis.

Questions about this item

Should I choose the 2 x 16 GB kit or a single 32 GB module?

The kit is sold as a matched pair of two 16 GB modules totalling 32 GB; a single 32 GB module is not offered in this listing.

Will the DDR4 2400 speed run at 2400 MT/s in my Synology NAS?

The modules are rated at DDR4 2400 (PC4-19200) and will operate at that speed if the NAS memory controller supports it; otherwise they run at the highest common speed.

Does the 288-pin ECC UDIMM interface limit the maximum capacity I can install?

Each 288-pin ECC UDIMM slot accepts one module; total capacity depends on how many slots your Synology system provides.
