Server memory upgrade

This 32GB DDR5 4800 CL40 ECC Registered RDIMM is built for HP Cray XD220v XD225v XD295v and XD670 servers. It adds capacity to workstations and servers that require registered error-correcting memory. Standard desktop boards cannot use this module type.

Compatibility checks

Verify that the system currently runs DDR5 ECC Registered DIMMs and that the memory slots accept 288-pin 2Rx8 modules at 1.1V. Do not mix with unbuffered or load-reduced memory. Match the existing speed of PC5-38400 for stable operation.

Thermals and power

The module operates at 1.1V without a heat spreader, relying on chassis airflow for cooling. Registered buffering adds minimal latency while supporting signal integrity in dense configurations. Power draw scales with the 4800 MT/s data rate under typical server workloads.
