Rank 1Rx8

  • 64 GB capacity across eight 8 GB modules for high-density workloads
  • DDR4 3200 speed with PC4-25600 bandwidth for responsive data throughput
  • ECC registered RDIMM design with 1Rx8 organisation for error correction and signal integrity
  • 2 V operating voltage for efficient power use in dense configurations
  • Validated compatibility with Dell Precision 7865 workstations for reliable integration

Dell Precision 7865 64GB ECC RDIMM Kit

This 64GB kit contains eight 8GB DDR4 3200 registered DIMMs built for the Dell Precision 7865 workstation. ECC error correction and registered buffering protect data integrity in professional workloads. The modules run at 1.20V with CL22 latency for stable server-class operation. IT teams choose this configuration for memory-intensive tasks that demand reliability.

288-Pin Registered Design With Major OEM Chips

Each stick uses Samsung, Micron or Hynix components on a standard 288-pin RDIMM PCB without a heat spreader. Registered signalling reduces electrical load on the memory controller when all eight slots are populated. The low-profile form factor fits dense workstation chassis without clearance issues. Installation follows the system manual for correct population order.

Upgrade Path From Smaller Capacity Or Non-ECC Memory

Replacing a partial kit or non-ECC modules with this matched 64GB set enables full-channel bandwidth and error detection. The jump is worth it when workloads exceed current capacity or require ECC for compliance. Systems already running a full complement of identical RDIMMs gain no benefit from this kit.

Questions about this item

What does the DDR4 3200 PC4-25600 rating mean for real-world speed?

The modules run at 3200 MT/s with CL22 latency, delivering the standard DDR4 3200 data rate for registered ECC workloads.

What physical slot and clearance does the 288-pin RDIMM need?

Each stick is a standard 288-pin DDR4 RDIMM without a heat spreader, so it fits any DDR4 RDIMM slot with normal vertical clearance.

What is the correct order to populate the eight 8 GB modules in a Dell Precision 7865?

Follow the 7865 service manual’s DIMM sequence — typically fill one channel per CPU first, then balance across channels — and seat each RDIMM until the ejectors click.
