SuperMicro DDR5 64GB RDIMM module

This registered ECC DDR5 module provides 64GB of capacity at 4800MT/s with CL46 latency and 1.1V operation. It uses a 2Rx4 organisation and 288-pin form factor designed for SuperMicro server and workstation platforms. The module targets IT professionals who need validated memory for mission-critical environments.

Single-module kit with registered ECC

The package contains one 64GB stick, so capacity scales in 64GB increments per populated slot. Registered buffering and on-die ECC improve signal integrity and data reliability under sustained workloads. Samsung, Micron or Hynix major-OEM DRAM chips are used depending on production batch.

Verify DDR5 RDIMM slot availability

Confirm your SuperMicro motherboard supports DDR5 registered DIMMs and has a free 288-pin slot before ordering. Mixed-rank or mixed-speed populations can limit reachable frequencies, so check the platform memory guide for approved configurations. No heat spreader is fitted, so ensure chassis airflow meets vendor thermal limits.

Questions about this item

Will the 2Rx4 RDIMM chips ever need replacement?

The Samsung, Micron or Hynix DRAM chips are rated for continuous server operation and carry a lifetime replacement warranty from NEMIX RAM.

What limits sustained throughput on this DDR5 4800 module?

The CL46 CAS latency and 1.10 V operating voltage set the ceiling for sustained bandwidth under heavy registered loads.

How much heat does the 64 GB stick produce at 1.1 V all day?

Running at 1.10 V without a heat spreader, the module stays within standard DDR5 thermal limits for 24/7 server workloads.
