About the HPE DDR5 128GB 5600 MT/s RDIMM
HPE DDR5 128GB 5600 MT/s RDIMM — next-generation memory delivering 5600 MT/s throughput and 128GB capacity per module for HPE ProLiant Gen11 servers. Part number 876988-B21 combines high-speed DDR5 architecture with registered buffering and native on-die ECC for mission-critical infrastructure.
This HPE memory module is engineered for data center environments where uptime and reliability cannot be compromised. The 288-pin RDIMM form factor with 2Rx4 rank configuration supports dense, scalable deployments across enterprise platforms. Native DDR5 on-die ECC and registered buffering provide single-bit error correction and multi-bit error detection, reducing downtime from transient memory faults. Operating at 1.1V with CAS latency CL46, this module balances performance and power efficiency across the 0–85°C operational window. Infrastructure architects and storage engineers selecting memory for virtualization, database, and high-performance computing workloads will find this capacity and speed profile essential for modern HPE deployments.
Typical Enterprise Deployment Scenarios
- Virtual machine hypervisors running 50+ concurrent instances with per-VM memory allocation exceeding 2–4GB
- In-memory database systems (SAP HANA, Oracle) requiring sub-100ns latency and multi-terabyte aggregate capacity
- Real-time analytics and big data processing clusters where node-level memory bandwidth directly impacts query performance
- High-frequency trading and financial modeling platforms benefiting from DDR5 speed and ECC reliability
- Backup and disaster recovery appliances consolidating multiple workloads on fewer physical servers
