Product Description

P50313-B21 HPE 128GB Quad Rank x4 DDR5-4800 EC8 Registered 3DS Smart Memory Kit

Product Overview

The P50313-B21 HPE 128GB (1x128GB) Quad Rank x4 DDR5-4800 CAS-46-39-39 EC8 Registered 3DS Smart Memory Kit is an enterprise-grade, high-density DDR5 memory module purpose-built for HPE ProLiant Gen11 servers. Leveraging advanced 3D Stacking (3DS) technology, it delivers an industry-leading 128GB capacity in a single 288-pin RDIMM form factor, enabling extreme memory density for memory-intensive workloads. Operating at 4800 MT/s (PC5-38400) with precisely tuned CAS-46-39-39 timings, this module balances bandwidth and latency to support virtualization, in-memory databases, cloud infrastructure, and big data analytics. As an HPE SmartMemory-qualified component, it integrates enterprise-class reliability features, proactive health monitoring, and full compatibility with HPE's server ecosystem, ensuring mission-critical uptime and performance.

Key Features & Benefits

Ultra-High Density via 3DS Technology

This module uses 3D Stacking (3DS) to achieve 128GB per DIMM, maximizing memory capacity per server while minimizing slot usage. The Quad Rank x4 (4Rx4) architecture optimizes memory channel efficiency and parallel data access, making it ideal for multi-core processors and high-density virtual machine deployments. This design supports extreme total memory configurations, critical for large-scale virtualization and in-memory computing environments.

Balanced Performance & Low Latency

Running at DDR5-4800 MT/s with CAS-46-39-39 timings, the module provides robust bandwidth and responsive latency for data-hungry applications. Compared to DDR4, it offers significant throughput improvements while maintaining power efficiency, making it suitable for mixed workloads in modern data centers.

Enterprise-Grade Reliability & RAS

Equipped with full ECC (Error Correcting Code), it detects and corrects single-bit and multi-bit errors in real time, preventing data corruption and unplanned downtime. The EC8 Registered design enhances signal integrity, reduces electrical noise, and supports dense memory configurations in multi-socket servers. Integrated with HPE Active Health System, it enables continuous monitoring, predictive failure alerts, and automated diagnostics for proactive maintenance.

HPE Ecosystem Compatibility

Fully validated and optimized for HPE ProLiant Gen11 servers (including DL325, DL345, DL385 Gen11) and HPE Synergy compute modules, this SmartMemory unlocks HPE-specific performance tuning, power management, and configuration features not available with generic memory. It uses a standard 288-pin RDIMM form factor for easy installation and supports hot-swap capability for non-disruptive upgrades.

Energy Efficiency & Compliance

Designed for eco-friendly data center operations, the module operates at 1.1V, significantly lowering power consumption and heat output compared to DDR4 memory. HPE SmartMemory dynamically adjusts power usage based on workload demand to maximize performance per watt. The module is TAA compliant, supporting deployment in government projects and regulated industries.

Frequently Asked Questions (FAQ)

Q1: Is this memory compatible with HPE Gen10 or older servers?

A1: No. This module is engineered exclusively for HPE ProLiant Gen11 servers and is not backward-compatible with Gen10 or earlier platforms due to architectural and electrical differences.

Q2: Can I mix P50313-B21 with other DDR5 memory modules?

A2: For optimal stability and performance, HPE strongly recommends using identical memory modules (same part number, capacity, speed, rank, and timings). Mixing configurations may result in reduced performance or compatibility issues.

Q3: What is 3DS (3D Stacking) technology?

A3: 3DS technology stacks multiple DRAM dies vertically, enabling higher memory density in a single DIMM. This allows 128GB capacity in a standard form factor, supporting larger memory configurations without increasing physical space.

Q4: Does this memory require special installation procedures?

A4: No special tools are required. Follow standard anti-static procedures and refer to your server user manual for proper DIMM installation guidelines.

Q5: What is covered under the 3-year warranty?

A5: 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.
