HPE 64GB DDR4-2933 ECC Load Reduced DIMM — P00926-B21

The HPE P00926-B21 is a 64GB DDR4-2933 (PC4-23466) ECC Load Reduced DIMM (LRDIMM) in a quad-rank 4Rx4 configuration for HPE ProLiant Gen10 servers. Operating at 1.2V with CL21 latency, the load-reduced buffer allows higher rank counts per channel, enabling maximum memory density configurations in memory-intensive enterprise deployments.

Key Features

Frequently Asked Questions

What is the difference between P00926-B21 (LRDIMM) and P03054-791 (RDIMM) for the same 64GB capacity?

P00926-B21 is an LRDIMM using a load-reducing buffer that lowers electrical load on the memory bus, enabling higher population density. P03054-791 is an RDIMM — RDIMMs generally offer slightly lower latency but may be limited at full channel population. Consult HPE QuickSpecs for max population per type.

Can P00926-B21 LRDIMMs be mixed with RDIMMs in the same server?

No — mixing LRDIMM and RDIMM types in the same server is not supported. All installed DIMMs must be of the same type across all channels.

Is P00926-B21 compatible with HPE ProLiant Gen9?

No — DDR4-2933 is a Gen10 specification. Gen9 platforms support DDR4-2133 or DDR4-2400 and are not compatible with this module.
