64GB DDR5 4800 ECC RDIMM for servers

This HPE Smart Memory kit delivers 64GB of DDR5 4800 (PC5 38400) capacity in a single 288-pin RDIMM. It targets enterprise servers that require registered ECC memory for data integrity and high-density configurations.

288-pin RDIMM installs in standard DDR5 slots

The module seats like any DDR5 RDIMM: align the notch, press until the ejectors click, and the system detects it at 4800 MT/s with CL40 40-39-39 timings. Issues usually arise when mixing ranks or speeds across channels, or when the platform BIOS lacks support for 2Rx4 registered DIMMs.

Verify DDR5 RDIMM support and 1.10V operation

Before ordering, confirm the server motherboard accepts DDR5 registered ECC DIMMs at 1.10V and can run 2Rx4 modules at the rated speed. Check the qualified vendor list and BIOS revision for P50312-B21 compatibility; some platforms limit rank-per-channel counts or maximum memory speed.

Perguntas sobre este artigo

How can I confirm the HPE P50312-B21 is running at DDR5 4800 after installation?

Check the memory speed in the server BIOS or use a tool like dmidecode; it should report 4800 MT/s and PC5 38400 bandwidth.

What is included with the HPE P50312-B21 and what else is needed?

The kit contains one 64GB 288-Pin DDR5 RDIMM; additional modules must be purchased separately to fill other slots.

Which capacity and rank option should I choose for this model?

This part is a single 64GB 2Rx4 module; select it when you need that density and rank configuration.
