64GB DDR5-4800 ECC Registered RDIMM

This 64GB DDR5 module runs at 4800MHz with a CAS latency of 40 and operates at 1.1V. It uses a 2Rx4 organisation and a 288-pin registered form factor with on-die ECC for error correction.

Suited for DDR5 servers needing registered ECC

This module fits servers that require DDR5 4800MHz PC5-38400 registered RDIMMs with ECC. It is not for desktop PCs or workstations that accept only unbuffered memory, nor for systems that cannot support registered DIMMs.

Registered DDR5 4800MHz

The single specification that determines fit is the registered DDR5 4800MHz PC5-38400 interface with ECC. Only platforms designed for this exact memory type will accept the module.

Questions about this item

Will the 288-pin DDR5 RDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR5 RDIMM form factor with 1.1 V operation; verify your platform supports DDR5 registered ECC memory before purchase.

What is the correct seating procedure for this registered ECC module?

Align the key notch with the slot, press firmly until both retention clips click, and confirm the module height clears any CPU cooler or chassis obstruction.

When should I plan to replace this 64 GB DDR5 4800 MHz kit?

Replace if memory diagnostics report uncorrectable ECC errors, the system fails POST with the module installed, or a platform upgrade requires a different speed or capacity.
