Server-grade DDR5 for PowerEdge R760xa R860 R960

This 64GB DDR5 4800 ECC Registered RDIMM is built for Dell PowerEdge R760xa, R860 and R960 servers. It delivers 64GB of error-correcting memory in a single 288-pin module running at 1.1V. The registered design adds stability for multi-DIMM configurations in enterprise workloads.

Replaces Dell part AC239379 SNPJ52K5C/64G

This module directly replaces Dell part numbers AC239379 and SNPJ52K5C/64G. The upgrade is worthwhile when expanding memory capacity for virtualisation, database or compute-intensive tasks on the supported PowerEdge platforms. It cannot be mixed with unbuffered or load-reduced ECC memory, so homogeneous population is required.

64GB single-module capacity with ECC headroom

The 64GB density provides substantial headroom for large datasets and high VM counts per socket. CL40 latency at 4800 MT/s supports throughput demands of DDR5-4800 server platforms. Workloads exceeding per-module capacity or requiring mixed memory types will need a different configuration.

Questions about this item

Does the 288-pin DDR5 RDIMM fit the DIMM slots in a PowerEdge R760xa, R860 or R960?

Yes, the 288-pin form factor matches the DDR5 RDIMM slots used in those PowerEdge servers.

What is the correct installation sequence for the 2Rx4 registered modules in a PowerEdge R760xa?

Populate slots according to the server's memory-channel guide, installing identical 2Rx4 modules per channel; the common error is mixing registered and unbuffered DIMMs.

When should the 64GB ECC registered module be replaced if correctable errors begin to appear?

ECC will correct single-bit errors, but a rising correctable-error count in the system log signals the module should be swapped before uncorrectable errors occur.
