64GB DDR5 4800 ECC RDIMM

This 64GB DDR5 4800 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It suits IT administrators upgrading IBM-Lenovo systems using part numbers 4X77A77033, 4X77A81442 or 03GX338. Buyers needing unbuffered UDIMMs or non-ECC memory for desktop platforms cannot use this module.

Capacity and headroom

A single 64GB rank 2Rx4 module delivers high density for multi-socket servers running virtualisation, databases or large datasets. The DDR5 4800 speed at 1.10V provides bandwidth headroom for memory-intensive workloads, while ECC and registered buffering protect data integrity. Systems limited to lower maximum module capacities or fewer DIMM slots will not accommodate this configuration.

Build fit

The 288-pin DDR5 RDIMM form factor requires a motherboard with registered DIMM support and DDR5 memory controllers. No heat spreader is fitted, so airflow in the chassis must be adequate for sustained loads. The module frees additional DIMM slots for further expansion where the platform allows. Mixing with different ranks, speeds or voltages is not supported by this specification.

Questions sur cet article

Will this 64GB DDR5 4800 RDIMM work in a server that currently has 288-pin DDR5 RDIMMs installed?

The module uses the standard 288-pin DDR5 RDIMM form factor at 4800 MHz. It will operate alongside existing DDR5 RDIMMs if the platform supports mixed capacities and the same registered ECC configuration.

How can I confirm the ECC RDIMM is running at 4800 MHz with CAS latency 40 after installation?

Enter the BIOS or UEFI and check the memory information screen; it should report 4800 MT/s, CL40, 1.10 V and ECC registered status for the new 64GB module.

Does the single 64GB 2Rx4 module ship with a heat spreader or any extra cables?

The module has no heat spreader and includes no cables or brackets; only the RDIMM itself is supplied.
