HPE 128GB DDR4-2400 ECC Load Reduced DIMM — 809086-091

The HPE 809086-091 is a 128GB DDR4-2400 (PC4-19200) ECC Load Reduced DIMM carrying an HPE factory/OEM configuration suffix for HPE ProLiant Gen9 servers. With octal-rank 8Rx4 architecture, 1.2V operation, and CL20 latency, it provides the same maximum per-slot DDR4-2400 density as the 809208-B21 option kit in a factory-configured procurement format.

Key Features

• 128GB 8Rx4 LRDIMM factory variant — same specifications as 809208-B21 in -091 configuration
• DDR4-2400 load-reduced octal-rank design for maximum Gen9 per-slot memory capacity
• ECC protection with LRDIMM buffer for enterprise reliability at 128GB per slot
• 1.2V low-voltage 288-pin DDR4 for energy-efficient high-density server memory

Frequently Asked Questions

Is 809086-091 interchangeable with 809208-B21?

Yes — both are HPE 128GB DDR4-2400 8Rx4 ECC LRDIMM modules for ProLiant Gen9 with identical specifications. 809086-091 is the factory/OEM configuration variant and 809208-B21 is the option kit — they are functionally interchangeable.

What does the -091 suffix mean on 809086-091?

The -091 suffix is an HPE factory/OEM configuration designation, similar to -081 on other HP part numbers. It indicates a factory-integrated procurement channel rather than a retail option kit (-B21) or spare part (-001).

Can 809086-091 operate in HPE ProLiant Gen10 servers?

DDR4-2400 LRDIMMs may function in Gen10 platforms but will likely operate below the Gen10 native DDR4-2666/2933 speeds. Confirm compatibility with HPE ProLiant Gen10 QuickSpecs before deployment.

The HPE 809086-091 128GB DDR4-2400 LRDIMM is the factory-configured variant for maximum-density HPE ProLiant Gen9 memory deployments. Get it in stock today at a competitive price.
