628974-081 HPE 16GB 1333mhz Pc3-10600 DDR3 RAM.

HPE 628974-081 16GB DDR3 Server Memory Overview

The HPE 628974-081 features a substantial 16GB memory capacity, engineered specifically for enterprise server environments where robust performance and reliability are paramount. This single module configuration allows for flexible server memory scaling, enabling IT administrators to populate multiple DIMM slots to achieve optimal total memory configurations ranging from 16GB to several hundred gigabytes depending on server platform capabilities.

Memory Technology and Architecture

Utilizing advanced DDR3 SDRAM technology, this module operates at 1333MHz (PC3-10600) with CAS Latency 9 timing, delivering efficient data transfer rates of up to 10,600 MB/s. The Double Data Rate 3 architecture enables two data transfers per clock cycle, significantly improving bandwidth over previous generation DDR2 memory while maintaining optimized power efficiency through lower operating voltages.

Advanced Memory Features

ECC Technology Implementation

Error Correcting Code (ECC) functionality represents a critical component of this memory module's reliability architecture. ECC technology detects and corrects single-bit memory errors automatically, while also detecting double-bit errors that could potentially lead to system crashes or data corruption. This proactive error management ensures continuous system operation and data integrity, making it particularly valuable for mission-critical applications and servers requiring 24/7 availability.

Registered DIMM Architecture

The registered (buffered) design incorporates advanced memory buffer chips that sit between the memory controller and DRAM chips. These buffers reduce electrical load on the memory controller by handling signal timing and drive requirements, enabling support for higher memory densities and more DIMMs per channel. This architecture significantly improves signal integrity and system stability in memory-intensive applications and multi-processor server configurations.

Performance Optimization Guidelines

Memory Population Best Practices

For optimal performance in multi-channel memory architectures, install identical HPE 628974-081 modules in symmetrical slots across memory channels. This configuration enables interleaving and parallel access patterns that maximize available memory bandwidth. Mixed installations with different memory capacities or specifications may force systems to operate at the lowest common performance denominator, potentially negating the performance advantages of this high-speed memory technology.

Thermal Management Considerations

The module incorporates enterprise-grade thermal sensors and spreaders that work in conjunction with HPE server cooling systems to maintain optimal operating temperatures. Proper airflow across memory modules is essential for sustained performance, particularly in high-ambient temperature environments or systems operating under continuous heavy memory utilization patterns.

Enterprise Applications and Use Cases

In virtualized server environments, the HPE 628974-081 provides the high-density, reliable memory foundation necessary to host multiple virtual machines simultaneously. The ECC protection ensures guest OS stability while the registered architecture maintains performance consistency across heavily loaded hypervisors such as VMware vSphere, Microsoft Hyper-V, and Citrix Xen Server.

Database Server Implementation

Database management systems including Microsoft SQL Server, Oracle Database, and MySQL benefit significantly from the module's combination of capacity, speed, and reliability. The 16GB capacity allows for substantial database buffer pool allocations, reducing physical I/O requirements and improving query performance for both OLTP and data warehousing workloads.

Memory-Intensive Workloads

Applications with substantial memory working sets, including in-memory databases, scientific computing, large-scale caching systems, and big data analytics platforms, achieve significantly better performance through the module's high-bandwidth architecture and large capacity per DIMM slot.

Reliability

Constructed using enterprise-grade DRAM components and rigorous manufacturing processes, the memory module undergoes extensive testing and validation to ensure compatibility and reliability. The use of high-quality printed circuit board materials with optimized signal routing preserves signal integrity at the 1333MHz operating frequency, minimizing timing errors and system instability.

Firmware

The module seamlessly integrates with HPE 628974-081 Integrated Lights-Out (iLO) management technology, providing detailed memory health monitoring, predictive failure analysis, and thermal management capabilities. This integration enables proactive maintenance and alerting through HPE's Systems Insight Manager and One View management platforms, allowing IT staff to monitor memory status remotely and plan maintenance activities before issues impact system availability.

DDR3 Memory Technology Advantages

The PC3-10600 designation indicates a peak theoretical bandwidth of 10,600 MB/s, 628974-081 representing a significant improvement over previous generation PC2-6400 (DDR2-800) 628974-081 memory's 6,400 MB/s capability. This bandwidth enhancement directly translates to improved application performance in memory-bandwidth-sensitive workloads including scientific computing, media processing, and large-scale data analysis.
