High-capacity server memory kit

This NEMIX RAM kit provides 4TB of DDR4 memory across sixteen 256GB registered DIMMs. It is built for enterprise servers that require error-correcting code and registered buffering at 3200MHz. The modules are not compatible with standard desktop or workstation platforms.

Registered ECC modules with major OEM chips

Each 288-pin RDIMM uses 8Rx4 organisation and operates at 1.2V with CAS latency 22. Samsung, Micron or Hynix DRAM components are used depending on supply. The registered design reduces electrical load on the server memory controller for stable operation at high density.

Installation requires qualified server hardware

Modules must be installed in a motherboard that supports DDR4 3200 registered ECC memory and 256GB per DIMM capacity. Population rules and BIOS settings vary by platform; incorrect configuration will prevent boot. Verify the server vendor memory qualification list before deployment.

Questions about this item

Will any of the 16 modules need replacement under normal server workloads?

The kit uses registered ECC DDR4 modules rated for continuous operation; individual DIMMs are only replaced if a hardware fault occurs.

What limits sustained throughput when all 16 slots are populated at 3200MHz?

The 8Rx4 organisation and CAS 22 timing set the electrical load and latency ceiling that the memory controller must meet.

How much heat and power does the full 4TB kit draw at 1.2V during all-day operation?

At 1.2V each 256GB registered DIMM runs within standard DDR4 thermal limits; total power scales with the 16 modules installed.
