Hewlett Packard Enterprise 815102-B21 Memory Module

The Hewlett Packard Enterprise 815102-B21 / 850883-001 / 840760-091 128GB DDR4 LRDIMM memory module provides 128GB of ECC RAM in a 288-pin DIMM for HPE ProLiant Gen9 and Gen10 servers, enabling dense memory configurations in enterprise data centers. This Load-Reduced (LRDIMM) module runs at 2666 MT/s (PC4-21300/PC4-2666V), with CAS latency CL22 (22-19-19), 1.2V operation, and an octal rank of 8Rx4 (3DS). It is designed for virtualization, large databases, analytics, and other memory-intensive workloads where reliability and uptime are critical. The module supports ECC and is compatible with HPE ProLiant Gen9/Gen10 server platforms, making it suitable for memory upgrades, capacity expansion, or replacing aging RAM in data-center environments.
