About the HPE 815102-B21 - HPE DDR4 128GB 2S4RX4 2666V
The HPE 815102-B21 is a Load-Reduced DIMM (LRDIMM) module with ECC support, engineered for HPE ProLiant Gen10 and Gen11 server platforms. This 128GB memory module delivers enterprise-grade reliability and performance for demanding workloads, making it an essential choice for IT infrastructure teams and storage architects managing mission-critical deployments across data centers in the UAE and beyond.
Built on HPE SmartMemory technology, the 815102-B21 (part number 815102-B21) is platform-authenticated to unlock full BIOS feature functionality and advanced memory protection capabilities. With a dual sub-rank, quad die rank configuration (2S4Rx4) and x4 DRAM width, this module operates at 2666 MT/s (PC4-2666V) using DDR4 technology at 1.2V nominal voltage. The 288-pin design ensures seamless integration into compatible HPE infrastructure, while ECC Error Correcting Code protection and support for Advanced ECC and Lockstep mode (platform-dependent) safeguard data integrity in high-availability environments. The module maintains stable operation across a 0°C to 85°C temperature range, meeting stringent enterprise standards.
