NEMIX RAM 64GB (2x32GB) DDR4 2666 ECC UDIMM CL19 1.2V 288-pin ASUS LOCKERSTOR NAS Memory

SKU CH-J9R0-1YDMD

64 GB DDR4 ECC UDIMM kit running at 2666 MHz CL19 for ASUS Lockerstor NAS

  • Total capacity64 GB (2 × 32 GB)
  • Rated speedDDR4 2666 (PC4 21300)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • ECC protection guards data integrity with built-in error correction
  • 64 GB kit expands NAS capacity using two 32 GB modules
  • DDR4 2666 speed matches PC4-21300 bandwidth for responsive workloads
  • Low 1.2 V operation reduces power draw and heat output
  • Validated compatibility with ASUS Lockerstor NAS ensures reliable installation

Compatible NAS Upgrade Kit

This 64 GB kit uses two 32 GB DDR4 ECC UDIMM modules validated for ASUS LOCKERSTOR NAS systems. It targets administrators who need to expand memory capacity in supported network-attached storage appliances.

Build Integration Requirements

The modules install into standard 288-pin DDR4 slots and operate at 1.2 V without a heat spreader. ECC unbuffered design preserves data integrity while leaving DIMM height clearances unchanged for tight NAS chassis.

Sustained Load Behaviour

Rated at DDR4 2666 (PC4-21300) with CL19 latency, the 2Rx8 organisation maintains stability during continuous workloads. All modules undergo stress testing under load before shipment to verify long-term reliability.

Questions about this item

Does the CL19 latency limit throughput when the NAS runs sustained workloads?

CL19 is the rated CAS latency at DDR4 2666; sustained throughput will follow that timing under load.

How much heat or power does the kit draw when the NAS operates all day?

Each module runs at 1.20 V with no heat spreader; total power scales with the 64 GB capacity under continuous use.

Which ASUS Lockerstor NAS models accept this 288-pin DDR4 ECC UDIMM kit?

The kit is validated for the ASUS LOCKERSTOR AS-32GECD4-U NAS; other models need manual verification.
