64GB DDR5 ECC RDIMM for Micron servers

This 64GB DDR5 module runs at 4800MT/s with CL40 latency and 1.1V operation. It uses a 2Rx4 registered ECC design on a 288-pin form factor for Micron server and workstation platforms. The registered buffer and error-correcting code protect data integrity in multi-socket environments.

Sustained throughput with registered ECC stability

Registered buffering reduces electrical load on the memory controller during continuous heavy workloads. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute jobs. The 4800MT/s rate and CL40 timing deliver consistent bandwidth without the voltage spikes seen in unbuffered consumer modules.

Direct slot insertion, verify RDIMM support first

The module installs like any standard 288-pin DIMM; align the key notch and press until the retention clips engage. No heat spreader is present, so airflow across the PCB is essential in dense chassis. Systems that require UDIMM or LRDIMM will not accept this RDIMM, and mixing registered with unbuffered modules prevents boot.

Questions about this item

How much power does the 1.1 V DDR5 4800 module draw under sustained server load?

The module operates at 1.1 V, the standard DDR5 voltage, which reduces power draw compared with previous DDR generations while maintaining 4800 MT/s throughput.

What motherboard slot and firmware support are required to run this 288-pin ECC RDIMM?

A server or workstation board with a DDR5 288-pin RDIMM slot and BIOS that enables ECC and registered memory operation is required.

Will this CL40 2Rx4 registered DIMM work in a system that currently uses unbuffered DDR5?

No — registered DIMMs need a motherboard chipset and memory controller designed for buffered operation; unbuffered consumer boards cannot use them.
