P69726-B21 EC8 Registered Smart Hpe Memory HPE 16GB Single Rank X8 DDR5-6400
P64986-B21 HPE 64GB (1x64GB) Dual Rank x4 DDR5-6400 CAS-52-52-52 EC8 Registered Smart Memory Kit
The P64986-B21 HPE 64GB (1x64GB) Dual Rank x4 DDR5-6400 CAS-52-52-52 EC8 Registered Smart Memory Kit is a high-speed enterprise-grade DDR5 memory module purpose-built for HPE ProLiant Gen11/Gen12 servers. Operating at an industry-leading 6400 MT/s (PC5-51200) with CAS-52-52-52 timings, it delivers exceptional bandwidth for performance-intensive workloads. Featuring Dual Rank x4 (2Rx4) architecture, EC8 Registered design, full ECC functionality, and HPE SmartMemory validation, this kit ensures robust reliability, signal integrity, and seamless compatibility within the HPE server ecosystem, making it ideal for virtualization, high-frequency databases, cloud infrastructure, and real-time analytics.
Running at DDR5-6400 MT/s (PC5-51200), this module provides significantly higher throughput than standard DDR5-4800/5600 modules, maximizing data transfer rates for latency-sensitive and bandwidth-hungry applications. The Dual Rank x4 (2Rx4) configuration optimizes memory channel efficiency and parallel data access, enhancing performance for multi-core processors and high-density virtual machine deployments.
Equipped with full ECC (Error Correcting Code), it detects and corrects single-bit and multi-bit errors in real time, preventing silent data corruption and unplanned system downtime. The EC8 Registered design buffers address and control signals, improving signal stability, reducing electrical noise, and enabling dense memory configurations in multi-socket server environments. Integrated with the HPE Active Health System, it provides continuous telemetry, predictive failure alerts, and automated diagnostics for proactive maintenance and maximum uptime.
Fully validated and qualified for HPE ProLiant Gen11/Gen12 servers and HPE Synergy compute modules, this SmartMemory kit unlocks HPE-specific performance tuning, advanced power management, and configuration features not available with generic third-party memory. It uses a standard 288-pin Registered DIMM (RDIMM) form factor for straightforward installation and supports hot-swap capability for non-disruptive upgrades and maintenance.
Designed for modern, energy-efficient data centers, the module operates at 1.1V, significantly reducing power consumption and thermal output compared to DDR4 memory. HPE SmartMemory dynamically optimizes power usage based on workload demand, improving overall performance per watt. The module is TAA-compliant, making it suitable for government and regulated industry deployments.

No. This module is designed exclusively for HPE ProLiant Gen11/Gen12 servers and is not backward-compatible with Gen10 or earlier platforms due to architectural and electrical differences.
For optimal stability and performance, HPE recommends using identical memory modules (same part number, capacity, speed, rank, and timings). Mixing configurations may result in reduced performance or compatibility issues.
EC8 Registered memory uses a register to buffer address and control signals, improving signal integrity, supporting higher memory capacities, and increasing overall system stability in multi-socket server environments.
No special tools are required. Follow standard anti-static procedures and refer to your server user manual for proper DIMM installation guidelines.
The warranty covers defects in material and workmanship under normal use. Support is available through HPE's global support network, including online case management, technical assistance, and replacement services.
Standard orders ship within 1-2 business days after payment verification. Bulk orders (10+ units) may require 3-5 business days for inspection and packaging.
International shipments are delivered via DHL, FedEx, or UPS. Domestic shipments use regional authorized carriers. Typical transit times are 4-6 business days for Asia-Pacific, 5-7 business days for North America and Europe, with possible delays for remote locations.
Each module is packed in anti-static, shock-resistant packaging to prevent ESD damage during transit. All units are factory-sealed with authentic HPE labeling and warranty certification.
Buyers are responsible for any applicable import duties, taxes, and customs fees in their destination country. A detailed commercial invoice is included for efficient customs clearance.
