The HPE 16GB 1600MHz PC3-12800 CL11 DDR3 SDRAM Memory

The HPE 688963-001 16GB 1600MHz PC3-12800 CL11 Dual Rank ECC Registered DDR3 SDRAM DIMM Memory is a high-performance server memory module designed for reliability, speed, and stability in enterprise environments. It is part of Hewlett Packard Enterprise’s advanced DDR3 memory lineup, crafted to deliver consistent performance for data-intensive workloads and server applications. This DDR3 SDRAM module combines error correction capabilities (ECC) and dual-rank architecture to optimize data integrity, throughput, and overall system responsiveness.

This 16GB Registered (RDIMM) memory operates at a clock speed of 1600MHz, ensuring high data transfer rates while maintaining low latency. As a PC3-12800 module, it provides exceptional compatibility with a wide range of HPE ProLiant servers and workstations. Designed to support multi-threaded workloads and virtualization, it enhances system scalability for businesses seeking dependable memory solutions.

Memory Capacity and Type

This memory module offers a total capacity of 16 gigabytes (16GB), providing sufficient bandwidth for demanding server applications, database management, and virtualization workloads. As a DDR3 SDRAM (Double Data Rate Type 3 Synchronous Dynamic Random-Access Memory) module, it delivers faster data access compared to its DDR2 predecessors while consuming less power, ensuring efficient and reliable performance.

Speed and Data Rate

Operating at a frequency of 1600MHz, the HPE 688963-001 module belongs to the PC3-12800 speed class. This means it can transfer up to 12.8 GB/s of data per channel, offering exceptional throughput for servers handling multiple processes simultaneously. The module’s low-latency CL11 (CAS Latency 11) timing ensures that commands are executed efficiently with minimal delay, which is crucial in high-performance computing environments.

Dual Rank

The dual rank configuration of this HPE memory module allows for improved memory throughput compared to single-rank modules. Dual rank memory accesses data across two ranks (groups of DRAM chips), enhancing parallel processing and providing a slight performance boost in applications that depend heavily on memory bandwidth.

Voltage and Power Efficiency

The HPE 688963-001 DDR3 module operates at a standard voltage of 1.5V, balancing performance and power efficiency. While DDR3 technology is not as power-efficient as newer DDR4 or DDR5 generations, it still provides stable energy consumption levels ideal for mid-generation servers and workstations that demand consistent performance.

Benefits of HPE 688963-001 16GB DDR3 ECC Memory

Using genuine HPE server memory modules offers several advantages that go beyond basic performance improvements. HPE-designed memory undergoes rigorous validation to ensure maximum stability, efficiency, and compatibility.

Enhanced System Reliability

The ECC technology ensures that even minor data errors are corrected automatically, which is vital for preventing application crashes, system downtime, and potential data corruption. For businesses that rely on constant uptime—such as financial institutions, data centers, and healthcare systems—this reliability translates to better operational efficiency.

Improved Server Performance

By increasing the total available memory and enabling faster access speeds, this module allows servers to handle more tasks simultaneously. Whether running virtualization environments, hosting applications, or managing databases, servers equipped with HPE 688963-001 modules benefit from improved responsiveness and faster data processing.

The HPE DDR3 Memory Technology

The HPE 688963-001 belongs to the DDR3 generation of memory, a technology known for providing an excellent balance between speed, latency, and energy efficiency. While newer generations like DDR4 and DDR5 have emerged, DDR3 continues to be widely used in legacy and mid-range server systems.

DDR3 vs. DDR2 and DDR4

Compared to DDR2, DDR3 delivers higher clock speeds, larger bandwidth, and reduced power consumption. On the other hand, DDR4 provides even faster speeds and better power efficiency but may not be compatible with systems designed for DDR3 memory. The HPE 688963-001 remains relevant for users maintaining or upgrading DDR3-based systems that still deliver substantial performance in production environments.
