About the P00918-B21

P00918-B21 delivers 64GB of dual-rank registered DDR4-2933 memory for high-density compute environments in HPE ProLiant Gen10 platforms. Designed for in-memory databases, large virtualization pools, and analytic pipelines, this module uses HPE SmartMemory architectures to verify hardware integrity, safeguard against data corruption, and monitor DIMM operating thermal margins.

Compatibility

Compatible with HPE ProLiant DL380 Gen10, DL360 Gen10, DL580 Gen10, DL560 Gen10, ML350 Gen10, Apollo 2000 Gen10, and Synergy 480 Gen10 systems configured with second-generation Intel Xeon Scalable processors. Backwards compatible with first-generation Xeon Scalable processors at 2666 MT/s bus clock rates.

How to identify a genuine unit

288-pin standard DDR4 registered module bearing HPE label marked with option part number P00918-B21, spare part number P03053-001, and assembly part number P06190-001. Features holographic genuine HPE security label placed adjacent to the EEPROM chip.

Buying used

Examine the module PCB for physical integrity, verifying that all SMD decoupling capacitors are intact and gold pins are free of debris or tarnishing. Check with HPE iLO 5 System Information to ensure that the DIMM is recognized as authentic HPE SmartMemory without SPD tampering.

FAQ

Why choose 64GB RDIMM over 64GB LRDIMM?

The 64GB dual-rank RDIMM avoids the additional buffer register delays inherent in load-reduced memory, offering slightly lower CAS latency while maintaining high system density.

Will P00918-B21 run at 2933 MT/s when 2 DIMMs per channel are populated?

On Cascade Lake-SP processors, dual-rank RDIMMs run at full 2933 MT/s speed in 1 DPC and 2 DPC configurations across supported channels.
