NEMIX RAM 8GB DDR3 1600 ECC UDIMM 2Rx8 1.35V server RAM

SKU CH-3W51-AKJ60

8 GB DDR3 1600 ECC UDIMM module with 2Rx8 organisation and 1.35 V operation

  • Capacity8GB
  • Type240-Pin DDR3 ECC UDIMM
  • SpeedDDR3 1600 (PC3 12800)
  • CAS LatencyCL11
  • Voltage1.35V
  • ECCYes
  • ECC protection guards data integrity with built-in error correction
  • DDR3 1600 speed delivers 12800 MB/s bandwidth for responsive workloads
  • Low 1.35V operation reduces power draw and heat in dense servers
  • Dual-rank 2Rx8 layout increases memory density per slot
  • 240-pin UDIMM fits standard DDR3 server and NAS motherboards

Capacity and configuration

This module provides 8 GB of DDR3 ECC UDIMM memory in a single 240‑pin stick. It is built for QNAP NAS appliances and other servers that accept unbuffered DDR3 DIMMs with 2Rx8 organisation.

Speed and headroom

Rated at DDR3 1600 (PC3 12800) with CL11 latency, the module delivers standard bandwidth for file serving and virtualization workloads. Capacity tops out at 8 GB per slot, so larger datasets will require additional populated slots.

Voltage and thermals

Operating at 1.35 V without a heat spreader, the DIMM runs cool in typical NAS chassis airflow. Power draw stays low under normal loads, and the lack of a spreader keeps the profile slim for dense slot spacing.

Questions about this item

Will this 1.35 V DDR3 ECC UDIMM run alongside my existing 1.5 V DDR3 modules?

The module is specified at 1.35 V; when mixed with 1.5 V sticks the system will run all memory at the higher voltage.

How can I confirm the 8 GB stick is detected at DDR3 1600 CL11 after installation?

Check the BIOS memory summary or run a tool such as CPU-Z to verify 8 GB, 1600 MT/s and CL11 timings.

Does the box include only the 240-pin UDIMM or are there extra brackets or cables?

Only the single 8 GB 240-pin ECC UDIMM is supplied; no brackets, cables or additional hardware are included.
