Sixteen green DDR4 LRDIMM modules with black heat spreaders and gold contacts

NEMIX RAM

NEMIX RAM 4TB 16x256GB DDR4 3200MHz ECC LRDIMM 8Rx4 CL22 1.2V

SKU CH-ZJR1-9NVP7

A 4 TB DDR4 server memory kit comprising sixteen 256 GB load-reduced ECC modules running at 3200 MHz with CL22 latency at 1.2 V

  • Total capacity4 TB (16 × 256 GB)
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latency22
  • Rated voltage1.2 V
  • Buffer typeLoad Reduced
  • Massive 4 TB capacity from sixteen 256 GB modules
  • DDR4 3200 MHz speed delivers high server throughput
  • ECC and load-reduced design protect data integrity
  • 8Rx4 organisation maximises density per DIMM slot
  • Low 1.2 V operation reduces power draw

High-Capacity Server Kit

This 4 TB kit contains sixteen 256 GB DDR4 3200 modules built for enterprise servers that support Load Reduced DIMMs. It is not compatible with standard desktop or workstation motherboards.

Practical Interface Limits

The DDR4 3200 standard delivers 25 600 MT/s bandwidth at 1.2 V with CL22 latency. Load Reduced buffering reduces electrical load on the memory controller so all sixteen slots can be populated at rated speed.

Upgrade Context

This kit replaces smaller RDIMM or LRDIMM configurations when an application needs maximum density per socket. The jump is worthwhile only when the platform supports 8Rx4 organisation and the workload benefits from the full 4 TB capacity.

Questions about this item

Should I pick the 16-module 4 TB kit or build the same capacity from smaller kits?

The 16 x 256 GB kit delivers 4 TB in a single matched set, ensuring identical 8Rx4 rank layout, CL22 timing and 1.2 V operation across all modules for server stability.

What does the 3200 MHz rating actually deliver inside a server?

At DDR4 3200 (PC4-25600) the modules transfer up to 25 600 MT/s per pin; real-world throughput depends on the CPU memory controller and populated channel count.

How does the 288-pin LRDIMM interface affect maximum capacity?

The 288-pin Load Reduced DIMM format buffers the electrical load, allowing 16 ranks per module (8Rx4) so the platform can address the full 4 TB without signal degradation.
