About the HPE 815101-B21 - HPE DDR4 64GB 4RX4 2666V
DDR4 2666 MHz, 64 GB capacity, load-reduced DIMM architecture — the HPE 815101-B21 delivers high-density memory for mission-critical enterprise servers. This LRDIMM module combines quad-rank (4Rx4) configuration with HPE's proven memory technology to support the demanding workloads of modern data centres across the UAE and beyond.
HPE designed the 815101-B21 to meet the needs of IT infrastructure teams and procurement professionals who require reliable, high-capacity memory expansion without compromising performance or system stability. The module operates at 2666 MHz (PC4-21300) with full ECC protection and 1.2V standard voltage, fitting seamlessly into HPE ProLiant Gen10, Gen10 Plus, and Gen11 servers that support LRDIMM-compatible slots. HPE Smart Memory and Advanced Memory Protection features — including online spare, mirroring, and lockstep options on compatible platforms — ensure data integrity and uptime. The 288-pin DIMM form factor and 72-bit memory bus width (64-bit data plus 8-bit ECC) align with enterprise JEDEC standards. Full integration with HPE iLO diagnostics and health monitoring provides real-time visibility into module performance and health across your infrastructure.
Built for longevity and compliance, this DDR4 memory module carries RoHS certification and operates reliably across the standard JEDEC temperature range of 0°C to 85°C, making it suitable for both air-cooled and liquid-cooled server environments. Infrastructure architects, storage specialists, and IT procurement teams selecting HPE memory upgrades for ProLiant deployments will find the 815101-B21 a proven choice that balances capacity, performance, and cost-effectiveness.
