Overview
The HPE 835955-B21 is a 16GB DDR4-2666MHz SmartMemory Registered DIMM — the entry-level server memory for HPE ProLiant Gen10 platforms. This module is the go-to choice for cost-conscious deployments where the workload doesn’t demand high memory density: file servers, DNS, DHCP, print servers, and lightweight application hosting. Despite its smaller capacity, it carries full SmartMemory features including iLO authentication and Advanced ECC.
