64GB DDR5-4800 Registered ECC Module

This 64GB DDR5-4800 registered ECC module targets enterprise servers and workstations that require maximum memory capacity with error correction. The dual-rank 2Rx4 organization helps maximize installed memory within limited DIMM slots. It is not suited for consumer desktop platforms or systems lacking registered memory support.

Thermal and Power Profile

Operating at 1.10V, this DDR5 module maintains standard server memory power characteristics under normal workloads. Registered buffering reduces electrical load on the memory controller, contributing to stable operation in densely populated configurations. Thermal output scales with capacity and rank count in multi-DIMM deployments.

Upgrade Path and Value

This module replaces lower-capacity DDR5 registered DIMMs or expands existing populations to increase total system memory. The jump is worthwhile when applications are constrained by memory capacity rather than bandwidth or latency. Systems already running DDR5-4800 registered memory gain density without changing platform infrastructure.

Highlights

  • High-capacity 64GB module expands server memory
  • DDR5 4800 speed accelerates data-intensive workloads
  • ECC parity registered design protects data integrity
  • Dual-rank 2Rx4 architecture boosts memory throughput
  • Low 1.10V operation reduces power consumption

Questions about this item

How do I install this 64GB DDR5 4800 registered DIMM, and what step is often missed?

Align the notch with the slot key, press firmly until both latches click, and ensure the server BIOS is configured for registered ECC memory at 1.10V.

What maintenance or replacement will this Micron MTC40F2046S1RC48BA1R module need over time?

No routine maintenance is required; if a correctable ECC error count rises, replace the module to maintain data integrity.

What limit appears first when this 2Rx4 CL40 kit runs sustained workloads?

The CAS latency of 40 cycles at 4800 MT/s sets the response-time floor before bandwidth saturation occurs.
