Two green DDR4 ECC UDIMM modules with black chips, 288 pins, 1.2V, 32GB kit

NEMIX RAM

NEMIX RAM 32GB (2×16GB) DDR4 2666MHz ECC UDIMM 2Rx8 1.2V 288-pin

SKU CH-3TDB-K4TJH

ECC UDIMM kit delivers 32 GB across two 16 GB DDR4 2666 modules at 1.2 V

  • Capacity32GB (2 x 16GB)
  • SpeedDDR4 2666 (PC4 21300)
  • CAS Latency19
  • Voltage1.2V
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • ECC protection guards data integrity in critical workloads
  • 32 GB kit (2 × 16 GB) expands server capacity

Capacity and configuration

This NEMIX RAM kit supplies 32GB of DDR4 memory as two 16GB unbuffered ECC UDIMMs running at 2666MHz with CAS latency 19. It targets servers and workstations that require error-correcting code protection without registered buffering.

What ECC UDIMM changes

ECC detects and corrects single-bit errors, improving data integrity for long-running workloads such as databases or virtualization hosts. The unbuffered design keeps latency low and allows direct installation in boards that do not support registered modules.

Build and connectors

Each module uses a standard 288-pin DDR4 edge connector and operates at 1.2V, matching the electrical specification for DDR4 UDIMMs. The 2Rx8 dual-rank organisation provides density per slot while remaining compatible with platforms that accept unbuffered ECC memory.

Questions about this item

Will the ECC UDIMM modules need replacement after a certain period?

The modules carry a lifetime replacement warranty, so they are intended to remain in service for the life of the system without scheduled replacement.

What limits sustained throughput on this DDR4 2666 kit?

The CAS latency of 19 at 2666 MT/s sets the timing ceiling for continuous read and write cycles.

How much heat and power does the 32 GB kit draw when running all day?

Each 16 GB module operates at 1.2 V, keeping power draw and thermal output low for an unbuffered DDR4 ECC DIMM.
