Rank 4Rx4

  • 256 GB total capacity for demanding server workloads
  • Four 64 GB modules enable full-channel population
  • DDR4 3200 speed with CL22 latency for responsive data access
  • ECC registered design detects and corrects memory errors
  • 2 V operation reduces power draw in dense configurations

256GB DDR4 ECC RDIMM kit

This NEMIX RAM kit provides 256GB of DDR4 memory across four 64GB registered DIMMs. It operates at 3200 MT/s with CL22 latency at 1.2V. ECC and registered buffering protect data integrity in server and workstation environments. The 288-pin modules are validated for the Dell Precision Workstation 7865.

Suited for memory-intensive server workloads

IT professionals expanding Dell Precision 7865 workstations or compatible OEM servers will match the factory configuration. The 4Rx4 organisation and registered design meet enterprise stability requirements. Builders needing unbuffered UDIMMs, non-ECC memory, or speeds beyond DDR4-3200 should select different modules.

Four-slot capacity with registered headroom

The 256GB total fills four DIMM slots, leaving no room for further expansion on a four-channel board. Each 64GB rank handles large datasets, virtualisation and database caching comfortably. Workloads requiring more than 256GB or higher bandwidth than PC4-25600 will exceed this kit's limits.

Questions about this item

Does my Dell Precision 7865 workstation need a specific CPU or chipset revision to run this 256 GB DDR4 3200 ECC RDIMM kit?

The kit is built for the Dell Precision Workstation 7865 series and uses the standard DDR4 3200 RDIMM interface that platform expects.

If I mix these 64 GB 4Rx4 modules with smaller DDR4 ECC RDIMMs I already own, will the system still boot at 3200 MT/s?

Mixing different capacities or ranks usually forces the memory controller to run at the lowest common speed and may disable quad-rank optimisations.

After installing all four modules, how can I confirm the server recognises the full 256 GB at CL22 1.2 V?

Check the BIOS memory information screen or run dmidecode / lshw on Linux; both will show 256 GB total, 3200 MT/s, CL22 timing and 1.2 V operation.
