The OWC 16GB DDR5-4800 ECC Registered RDIMM is a server memory upgrade for HP Cray XD220v, XD225v, XD295v, and XD670 systems that support this module type.
Recommended For
- IT administrators repairing or refreshing an HP Cray XD220v, XD225v, XD295v, or XD670 who need a single 16GB DDR5-4800 ECC registered DIMM matching the listed module type.
- Server operators adding or replacing memory in a listed Cray system who can follow HPE’s DIMM population rules and match the existing memory configuration.
- IT teams sourcing a server-class ECC registered module for a compatible system, rather than consumer desktop memory.
Real-World Use Scenarios
- A data-center technician replaces a failed or missing compatible DIMM in an HPE Cray XD220v, XD225v, or XD295v node; matching the server’s supported memory configuration can help return the node to service without changing its role in the cluster.
- An HPC administrator adds memory to a compatible XD220v, XD225v, or XD295v compute node so a workload can keep a larger working set in system RAM; the benefit depends on the application and the server’s DIMM population.
- When expanding a dual-processor Cray node, an administrator plans memory across processors and channels rather than adding a stick arbitrarily; HPE recommends balanced capacity and similar channel loading for optimal interleaving.
- A team operating a remote compute site or a larger HPC cluster uses a compatible DIMM to maintain or expand memory on an existing Cray node; the node can stay in its established workload pool, subject to its supported configuration.
