Detailed Specifications
HPE 815101-B21 - 64 GB Quad-Rank DDR4-2666 SmartMemory Module
Overview
The HPE 815101-B21 is a 64 GB quad-rank LRDIMM memory module designed for HPE ProLiant Gen9 and Gen10 servers, as well as HPE Synergy and Apollo systems needing high-capacity and high-bandwidth memory. It operates at DDR4-2666 MT/s (PC4-21300) with CAS latency of 19 and supports ECC and LRDIMM architecture for reliable server operation. This memory module fits 288-pin server DIMM slots and is a drop‐in upgrade for dense compute environments where memory capacity and throughput drive performance.
Key Features
64 GB capacity in a single 1×64 GB quad-rank LRDIMM module, ideal for high-density memory deployments.
DDR4-2666 MT/s speed with CAS latency 19-19-19 ensures bandwidth for virtualization, database caching, or in-memory workloads.
Designed with ECC and load-reduced technology (LRDIMM) for stability and compatibility in dual- or multi-socket servers.
Fully qualified for HPE ProLiant Gen9/Gen10, Synergy and Apollo server families×simplifies upgrade path and support.
