Hewlett Packard Enterprise 815101-B21 Memory Module

The Hewlett Packard Enterprise 815101-B21 is a 64GB DDR4 LRDIMM memory module engineered for enterprise servers, delivering high memory density and reliable performance for virtualization, database processing, and high-performance computing in data centers. This 288-pin DIMM operates at 1.2V, supports ECC, and is configured as Quad Rank (4Rx4) with a speed of 2666 MT/s (PC4-2666V), making it suitable for memory-intensive workloads in HPE ProLiant Gen9/Gen10 servers. Common replacements include HPE P00930-B21 64GB DDR4-2933 and HPE P06035-B21 64GB DDR4-3200, reflecting alternate memory options within the same 64GB DDR4 family for different performance profiles, while this module uses standard DIMM slot mounting in enterprise systems. Designed for enterprise data centers, virtualization platforms, cloud infrastructures, databases, and HPC workloads that demand large, reliable memory, this module is intended to be installed in compatible HPE ProLiant Gen9/Gen10 servers to upgrade capacity and sustain uptime.
