32GB DDR5 4800 ECC Registered DIMM

This Micron server memory module provides 32GB of DDR5 capacity at 4800 MT/s with CL40 latency. It uses a 288-pin RDIMM form factor and operates at 1.10V. The single-rank 1Rx4 design includes on-die ECC and registered signal processing for data integrity in multi-socket platforms.

Thermals noise and power draw

Standard DDR5 voltage of 1.10V keeps power draw low for high-density server configurations. Registered buffering reduces electrical load on the memory controller, aiding signal stability across populated channels. Passive operation produces no acoustic noise, relying on chassis airflow for thermal management.

What the registered ECC design changes

Registered signalling and ECC allow the module to function in dense channel populations where unbuffered memory would fail. Single-rank organisation supports maximum channel capacity per processor. 100% component and module testing targets mission-critical uptime requirements for enterprise workloads.

Questions about this item

How do I install the 288-pin DDR5 RDIMM, and what step is often missed?

Align the module key with the slot, press firmly until both retention clips click, and ensure the registered buffer engages; the step often missed is confirming the clips lock on both sides.

What maintenance or replacement will the 32 GB DDR5 4800 ECC registered module need later?

No routine maintenance is required; if a correctable error count rises, replace the module under the three-year limited warranty.

What limit appears first on this CL40 1.10 V DDR5 RDIMM under sustained load?

The CAS latency of 40 cycles at 4800 MHz sets the timing boundary before thermal or voltage limits are reached.
