FAQs

Q: Is this RDIMM or LRDIMM?
A: This is a DDR5 Registered DIMM (RDIMM), not an LRDIMM.

Q: Can I mix this module with LRDIMMs or non-registered memory?
A: No. Mixing RDIMMs with LRDIMMs or UDIMMs is not supported.

Q: Will this work in older DDR4-based ProLiant servers?
A: No. DDR5 modules are not backward compatible with DDR4 platforms.

Q: Do I need to install memory in pairs?
A: Follow your server’s memory population rules. Many platforms require channel-balanced population for optimal performance.

Q: Does Smart Memory require a specific firmware?
A: Smart Memory features are enabled on supported HPE platforms with current system firmware.
