64GB DDR5 ECC RDIMM for Dell PowerEdge

This single 64GB DDR5 4800 CL40 registered DIMM delivers ECC error correction for Dell PowerEdge R6625, R760, R7615 and R7625 servers. It operates at 1.1V with a 2Rx4 organisation and fits the 288-pin RDIMM slots in those platforms. The module is built to JEDEC PC5-38400 specifications for server-grade reliability.

Suits servers needing registered ECC memory.

This module is designed for workstations, NAS systems, servers and network switches that require registered ECC DDR5. It will not work in standard desktop computers that accept only unbuffered memory, and it cannot be mixed with load-reduced or unbuffered ECC modules in the same system.

One 64GB module adds substantial capacity headroom

A single 64GB stick provides a large capacity increment for multi-socket Dell PowerEdge platforms, supporting memory-intensive workloads such as virtualisation and large databases. Total capacity scales with the number of populated slots, while the 4800 MT/s speed and CL40 latency set the performance ceiling for the memory subsystem.

Questions about this item

Does this 288-pin DDR5 RDIMM require a Dell PowerEdge R6625, R760, R7615 or R7625 to operate?

Yes. The module is validated only for those four Dell PowerEdge servers and will not work in standard desktops or other platforms.

Can I mix this 64GB 2Rx4 ECC Registered module with existing ECC Load Reduced DIMMs in my R760?

No. The manufacturer states it cannot be mixed with ECC Load Reduced or unbuffered memory; all slots must use the same registered ECC type.

How do I confirm the 4800 CL40 1.1V module is running correctly after installation?

Check the server BIOS or iDRAC interface — it should report each installed DIMM as 64GB DDR5 4800MHz CL40 ECC Registered at 1.1V with no memory errors logged.
