Rank 4Rx4

  • 128 GB capacity across two 64 GB modules for large workloads
  • DDR4 3200 speed with PC4-25600 bandwidth for fast data transfer
  • ECC registered RDIMM design detects and corrects memory errors
  • 4Rx4 dual-rank organisation maximises density per DIMM slot
  • 2 V operation reduces power draw in Dell Precision 7865 workstations

Dell Precision 7865 kit

This 128GB kit contains two 64GB DDR4 RDIMM modules rated at 3200 MT/s with CL22 latency. It is built for the Dell Precision 7865 workstation and uses ECC registered technology for data integrity. The modules run at 1.2V and fit standard 288-pin DDR4 slots.

Registered ECC for stability

Registered buffering reduces electrical load on the memory controller, allowing the workstation to populate multiple slots without signal degradation. ECC corrects single-bit errors automatically, protecting long-running calculations and virtualised workloads. The kit requires a platform that supports DDR4 RDIMM and 4Rx4 organisation.

128GB headroom for heavy loads

Two 64GB modules provide 128GB total capacity, giving ample room for large datasets, multiple virtual machines and memory-intensive rendering. The 3200 MT/s speed and CL22 timing deliver consistent throughput within the rated specification. Workloads exceeding 128GB will need additional slots or higher-density modules.

Questions about this item

Does the CL22 latency limit throughput when the Dell Precision 7865 runs sustained workloads?

CL22 is the rated CAS latency at 3200 MT/s; the registered 4Rx4 design keeps timing stable under continuous load.

How much heat and power do two 64 GB modules draw during all-day operation?

Each module runs at 1.2 V with no heat spreader; registered ECC RDIMMs typically stay cool in server chassis airflow.

What motherboard feature must the workstation already have for this kit to function?

The system must support 288-pin DDR4 RDIMM slots with ECC and registered memory capability.
