HPE 16GB DDR4-2666 ECC Non-Volatile RDIMM — 825109-091

The HPE 825109-091 is a 16GB DDR4-2666 (PC4-21300) ECC Non-Volatile DIMM (NVDIMM) in single-rank 1Rx4 configuration and is a factory/OEM variant of the same NVDIMM platform as 845264-B21 and 874540-001. Delivering DRAM-speed persistent memory for HPE ProLiant Gen10, it is functionally identical and fully interchangeable with its option kit and spare counterparts in supported Gen10 configurations.

Key Features

Frequently Asked Questions

What does the -091 suffix on 825109-091 mean?

HPE uses numeric suffixes to denote factory, OEM, or regional configuration variants. The -091 suffix indicates a factory/OEM configuration — the hardware is functionally identical to the 845264-B21 option kit and 874540-001 spare part.

Is 825109-091 interchangeable with 845264-B21 and 874540-001?

Yes — all three are HPE 16GB DDR4-2666 ECC NVDIMM 1Rx4 modules with identical specifications. They are fully interchangeable in HPE ProLiant Gen10 supported NVDIMM configurations with the appropriate BBU installed.

Can 825109-091 be used without the HPE NVDIMM BBU?

Without the BBU, the NVDIMM may operate in DRAM-only mode (non-persistent). Data will not be preserved on power loss without the backup power module. Always install the HPE NVDIMM BBU to enable full flash-backed persistence functionality.

The HPE 825109-091 16GB DDR4-2666 NVDIMM factory variant delivers DRAM-speed persistent memory for HPE ProLiant Gen10 deployments. Get it in stock at the best price — order today.
