HPE 815098-B21 16GB DDR4-2666 Registered Memory Kit

This HPE DDR4-2666 Registered Smart Memory Kit provides 16GB of capacity for server environments. It is designed for SMB and enterprise customers requiring performance and capacity to manage total cost of ownership. The module supports server virtualization, cloud computing, and large database applications. High-quality DRAM materials reduce signal integrity issues to increase system reliability.

RDIMM Single Rank x4 DDR4-2666 Specification

The kit uses a 16GB RDIMM with a native speed of 2666 MTs and operates at 1.2V voltage. HPE DDR4-2666 server memory delivers up to 66 percent improvement in bandwidth for demanding workloads. Single Rank x4 organisation optimises density and signal integrity for compatible platforms. This specification determines compatibility with specific server memory slots and channel configurations.

Standard DIMM Installation and Compatibility Checks

The module measures 3.5 x 7.8 x 0.75 in, matching standard RDIMM dimensions for straightforward insertion into compatible slots. Installation requires aligning the key notch and applying even pressure until retention clips engage securely. Verifying the server qualified vendor list prevents boot failures or reduced memory speeds. Mismatched ranks or speeds across channels typically cause instability or capacity reporting errors.
