HPE P53628-0A1 128GB DDR5 ECC Memory Overview

The HPE P53628-0A1 128GB 5600MT/s PC5-44800 CL52 ECC EC8 DDR5 server memory module is a cutting-edge solution specifically engineered for enterprise-level performance and stability. As a New Sealed in Box (NIB) product, this DIMM offers unmatched quality assurance directly from the manufacturer, Hewlett Packard Enterprise. Its ECC (Error-Correcting Code) capability, ultra-high capacity, and blistering speed make it ideal for data-intensive operations such as virtualization, cloud computing, artificial intelligence, and high-performance databases.

Performance Benefits of DDR5 Technology

DDR5 memory introduces significant architectural improvements over its DDR4 predecessor. Designed to scale with the needs of high-performance computing, DDR5 provides superior bandwidth, energy efficiency, and reliability.

Higher Data Transfer Rates

With a speed of 5600 MT/s, the HPE P53628-0A1 ensures fast and reliable data movement between memory and CPU. This is essential for applications requiring real-time analytics and large data processing. The PC5-44800 classification reflects a data rate of 44.8 GB/s, offering a dramatic boost over older memory modules.

Improved Memory Bandwidth

DDR5 memory doubles the burst length and bank group architecture over DDR4, allowing more concurrent operations. This enhances multitasking capabilities, reduces latency in accessing memory, and helps improve system responsiveness.

Lower Power Consumption

Although DDR5 operates at similar voltage levels to DDR4, it introduces power management integrated circuits (PMICs) on the module itself. This reduces motherboard complexity and improves power efficiency, making it ideal for servers that demand energy-conscious solutions.

ECC EC8: Enterprise-Grade Reliability

The HPE P53628-0A1 utilizes ECC (Error-Correcting Code) technology with an EC8 design, ensuring real-time error detection and correction. This is a critical requirement in mission-critical systems where uptime and data integrity are paramount.

Benefits of EC8 ECC Implementation

• Detection and correction of single-bit errors
• Detection of double-bit errors (though not correctable)
• Reduced system downtime and data corruption
• Improved system uptime for enterprise-level workloads
• Increased overall hardware lifespan

Applications and Use Cases

This 128GB DDR5 ECC module is designed for modern enterprise environments. It supports applications that demand extreme memory capacity, consistent uptime, and rapid data throughput.

Enterprise Server Environments

Whether powering a high-availability file server, a database cluster, or virtualization host, the HPE P53628-0A1 ensures that memory is never a performance bottleneck. With its 128GB capacity, this module is especially beneficial for workloads that are memory-bound.

High-Performance Computing (HPC)

HPC workloads demand peak memory performance and reliability. The 5600MT/s data rate of this module accelerates simulations, data modeling, rendering, and other computational tasks that require massive memory access.

Virtualization & Hyper-Converged Infrastructure

Virtual machines require dedicated memory allocations. A 128GB module allows a single server to support dozens of VMs or containers with sufficient headroom, ensuring seamless operations in private clouds and hybrid deployments.

Compatibility and System Requirements

The HPE P53628-0A1 is certified for HPE ProLiant Gen11 servers and other compatible platforms that support DDR5 registered ECC memory. It’s crucial to verify compatibility with your server model, BIOS, and memory configuration before installation.

Supported Server Families

• HPE ProLiant Gen11 DL3xx and DL5xx series
• HPE Apollo systems designed for AI and ML workloads
• HPE Synergy composable infrastructure (Gen11 compatibility)
• OEM and white-box servers with DDR5 ECC RDIMM support

New Sealed in Box (NIB) Advantage

Purchasing the HPE P53628-0A1 in New Sealed in Box (NIB) condition guarantees that the product is brand-new, unused, and shipped in its original manufacturer packaging. This ensures:

Authenticity and Quality Assurance

NIB products are untouched and unmodified, preserving manufacturer factory testing standards. With original HPE packaging and serial numbers intact, you get traceable authenticity and full warranty eligibility.

Optimal Compatibility

HPE memory modules are designed, engineered, and tested for compatibility across the full range of HPE ProLiant and Apollo servers. This guarantees reliable operation without unpredictable behaviors.

Advanced Features and Architecture

The HPE P53628-0A1 DDR5 module is equipped with state-of-the-art features aimed at maximizing server efficiency and scalability.

On-Die ECC and Reliability Enhancements

DDR5 introduces on-die ECC (ODECC), which complements traditional ECC by correcting internal cell errors. This increases the overall stability of the memory module.

Dual-Channel DIMM Architecture

Each DDR5 DIMM contains two independent 32-bit channels. This architecture enables more efficient memory access, leading to lower latency and better multitasking.

Module Power Management IC (PMIC)

Integrated PMIC on DDR5 DIMMs improves power regulation and distribution across the memory module. This helps reduce heat output and ensures better voltage control under variable loads.

Technical Breakdown

JEDEC Standard Compliance

The P53628-0A1 adheres to JEDEC standards for DDR5 RDIMMs. It meets industry specifications for form factor, voltage, latency, and ECC functionality, ensuring broad interoperability with compliant systems.

Latency and Timing

With a CAS latency of CL52, this module offers excellent performance for the data rate it provides. Although DDR5 modules have higher CL values than DDR4, they also benefit from architectural improvements that mitigate latency effects.

Data Center Impact

In large-scale deployments, the reliability and performance of each memory module significantly affect the total cost of ownership (TCO). The HPE P53628-0A1 delivers:

• Reduced memory errors across clusters
• Improved workload density per server
• Lower energy costs due to efficient PMIC and ECC architecture
• Better thermal behavior for high-density environments
