Product overview for the HPE P07646-B21

In the dynamic landscape of modern technology, the efficiency and performance of server systems play a crucial role in ensuring smooth operations for businesses. One essential component that significantly contributes to the overall performance of a server is its memory module. This article delves into the specifics of the HPE P07646-B21 32GB DDR4 3200MHz Memory Module, exploring its features, benefits, and the impact it can have on server performance.

Understanding HPE P07646-B21 32GB DDR4 Memory ModuleArchitecture and Capacity

The HPE P07646-B21 is a memory module designed for servers, featuring a robust DDR4 architecture. With a capacity of 32GB, this module is optimized for data-intensive applications, providing ample space for processing and storing large datasets.

Speed and Efficiency

Operating at a speed of 3200MHz, this memory module ensures high-speed data transfer, enhancing the overall responsiveness of the server. The DDR4 technology employed in this module is known for its improved efficiency and reduced power consumption compared to its predecessors, contributing to a more sustainable and cost-effective server solution.

Technical Specifications

The HPE P07646-B21 utilizes DDR4 SDRAM (Synchronous Dynamic Random-Access Memory) technology. The module is configured as a 2rx4 dual-rank ECC registered RDIMM, which signifies its reliability and error-checking capabilities. The 288-pin design ensures compatibility with a wide range of server systems.

CL22 and X4

The CL22 (Column Address Strobe Latency) rating indicates the number of clock cycles needed to access a column of data in the memory array. A lower CL value signifies faster data retrieval, contributing to improved overall system performance. Additionally, the X4 classification denotes a dual in-line memory module (DIMM) with an x4 data width, enhancing data transfer rates.

Dual Rank

The dual-rank configuration implies that the memory module has two sets of memory banks. This design provides improved memory interleaving, enabling better parallelism in data access. Dual-rank modules are known for their ability to handle multiple tasks simultaneously, making them ideal for multitasking and demanding server applications.

ECC (Error-Correcting Code) Functionality

One of the standout features of the HPE P07646-B21 memory module is its ECC functionality. ECC is a vital error-checking and correcting mechanism that enhances the reliability of the server's memory by detecting and automatically correcting single-bit errors. This is crucial for mission-critical applications where data integrity is paramount.

Registered DIMM (RDIMM) Technology

The inclusion of Registered DIMM technology in the HPE P07646-B21 further enhances its reliability. RDIMMs use a register to buffer address and command signals, reducing the load on the server's memory controller. This buffering helps improve signal integrity and stability, especially in systems with large amounts of memory.
