Key Features of HPE 708643-S21 Memory

High Capacity 32GB Modules

Each HPE 708643-S21 module comes with 32GB of memory, which is essential for servers that handle large-scale databases, virtualization, or memory-intensive applications. Higher capacity modules like this allow IT administrators to consolidate workloads, reduce server counts, and enhance overall system efficiency. With 32GB per DIMM, your servers can efficiently manage multiple virtual machines (VMs) and heavy-duty enterprise applications without performance bottlenecks.

DDR3 PC3-14900 Performance

This memory module operates at 1866MHz (PC3-14900), providing fast data transfer rates that are crucial for enterprise operations. The higher clock speed ensures minimal latency and rapid access to frequently used data. Compared to lower-speed DDR3 modules, the 1866MHz frequency of the HPE 708643-S21 offers superior throughput, which is especially beneficial for transactional databases, analytical processing, and virtualization tasks.

ECC (Error-Correcting Code)

Error-Correcting Code (ECC) memory is critical in servers to prevent data corruption. The HPE 708643-S21 is an ECC module, meaning it can detect and correct single-bit errors automatically. This feature ensures data integrity and reliability, which is crucial for financial institutions, healthcare systems, and any organization where even minor data errors can result in significant issues.

Quad Rank X4

The Quad Rank X4 architecture provides higher density memory access and better load balancing across the memory channels. This design allows the server to achieve maximum memory bandwidth and take full advantage of the dual-channel or quad-channel memory architecture in HP ProLiant servers. Quad rank modules can also support larger overall memory capacities within a single server, making them ideal for scaling enterprise workloads.

240-Pin Form Factor

This memory module uses a 240-pin DIMM design, making it compatible with standard DDR3 DIMM slots on supported HP ProLiant servers. The form factor ensures easy installation and maintenance, with precise fitment that minimizes the risk of damage during module replacement or upgrades.

Genuine HP Memory for G8 Series

The HPE 708643-S21 is a genuine HP memory module, optimized for HP ProLiant G8 servers. Using genuine HP memory ensures complete compatibility with HP server firmware, diagnostics, and management tools. Non-genuine memory may not support advanced features like SmartMemory or HP’s Integrated Lights-Out (iLO) remote management, which can impact overall server performance and reliability.

Performance Benefits of HPE 708643-S21

Improved Data Transfer Speeds

With a speed rating of 1866MHz, the HPE 708643-S21 ensures rapid data transfer between the memory and the CPU. This is critical for applications that rely on real-time data processing, such as database management, virtualization, and high-performance computing. Faster memory reduces latency, enabling more responsive application performance and efficient handling of multiple workloads.

Load Reduced DIMMs (LRDIMMs)

LRDIMMs are designed to handle higher memory densities by reducing electrical load on the memory controller. This allows servers to support more modules per channel and maximize memory capacity without performance degradation. Ideal for enterprise applications, LRDIMMs are commonly used in high-end servers running virtualization, large databases, and analytics workloads.

Registered DIMMs (RDIMMs)

RDIMMs provide error detection and buffering between the memory controller and DRAM chips, supporting moderate-to-high memory capacities while ensuring stability. While not as high-density as LRDIMMs, RDIMMs remain suitable for general-purpose enterprise servers and applications requiring balanced performance and cost-effectiveness.

Smart Memory Technology

Many HP memory modules, including the HPE 708643-S21, support SmartMemory features, which allow the server to automatically optimize performance, monitor health, and manage error detection. This intelligent memory management ensures that your server runs at peak efficiency while preventing potential failures before they occur.

Enterprise Databases

High-capacity, fast DDR3 memory modules are essential for enterprise databases, where large amounts of data need to be processed quickly and accurately. The HPE 708643-S21 supports high transaction volumes and reduces query latency, making it ideal for Oracle, SQL Server, and SAP HANA applications.

High-Performance Computing (HPC)

In HPC clusters, memory bandwidth and stability are critical. The HPE 708643-S21 delivers high-speed performance and error-free operation, which is essential for scientific simulations, data analytics, and computational workloads.
