Server DDR5 ECC RDIMM

This 32GB DDR5 4800 ECC registered DIMM is built for HP and HPE servers and workstations that require registered memory with error correction. The module operates at 1.10V with a CAS latency of 40 and uses a 2Rx8 rank configuration on a 288-pin interface.

Upgrade from slower DDR5 or smaller capacity

Replacing lower-speed DDR5 modules or smaller-capacity sticks with this 32GB PC5-38400 unit increases memory bandwidth and total addressable memory in a single slot. The jump is worthwhile when workloads exceed current memory limits or when the platform demands registered ECC modules at the native 4800MT/s data rate.

Fits 288-pin RDIMM slots in compatible HP/HPE

The module installs directly into DDR5 RDIMM slots on supported HP and HPE server boards that accept P50311-B21, P56152-001, P43330-1A1, P43328-B21, P48501-001, or P43330-0A1 part numbers. Using registered ECC DIMMs frees the memory controller from parity duties and allows higher densities per channel than unbuffered alternatives.

Questions about this item

Will this 288-pin DDR5 module fit my HP server's RDIMM slots?

Yes, the 288-pin DDR5 RDIMM form factor matches the registered DIMM slots used by the listed HP/HPE part numbers.

Do I need to populate specific channels when installing this 2Rx8 registered module?

Follow your system manual for channel population rules; registered 2Rx8 modules often require specific slot order for multi-channel operation.

Does the lack of a heat spreader on this 1.10V module affect long-term reliability?

DDR5 runs at 1.10V standard voltage and the major-brand DRAM ICs are tested without a spreader for server airflow environments.
