Description
Product Overview
The 497765-B21 is a DDR2 SDRAM memory module manufactured by Hewlett-Packard (HP). It is designed for use in servers and other high-performance computing systems. This memory module provides high-speed data transfer, reliability, and security features that are essential for mission-critical applications. This article will explain in detail the key features and specifications of the HP 497765-B21 memory module.
DDR2 SDRAM Memory Module
DDR2 SDRAM (Double Data Rate 2 Synchronous Dynamic Random Access Memory) is a type of computer memory that provides faster data transfer rates than its predecessor DDR SDRAM. The HP 497765-B21 memory module is a DDR2 SDRAM memory module that operates at a clock speed of 800MHz. This means that it can transfer data at a rate of 800 million cycles per second.
Memory Capacity
The HP 497765-B21 memory module has a total capacity of 4GB, which is divided into two 2GB modules. This allows the memory to be installed in a dual-channel configuration for increased performance. The dual-channel configuration allows the memory controller to access two memory modules simultaneously, which effectively doubles the available bandwidth.
DIMM Form Factor
The HP 497765-B21 memory module uses a DIMM (Dual In-Line Memory Module) form factor. DIMMs are the most common form factor used in servers and high-performance computing systems. They are designed to be easily installed and replaced by the user or a technician.
ECC and Chipkill Technology
The HP 497765-B21 memory module supports ECC (Error Correction Code) technology, which helps to detect and correct errors in data that is being transferred to and from the memory. This is an important feature for mission-critical applications, as it helps to ensure the integrity of data and prevent system crashes.
In addition to ECC technology, the HP 497765-B21 memory module also supports Chipkill technology. Chipkill is a type of memory redundancy technology that provides protection against multiple bit errors in a memory module. It works by dividing the memory into multiple banks, each with its own error correction circuitry. If one bank experiences a bit error, the Chipkill technology can correct it and prevent it from affecting the overall performance of the system.
Registered Memory
The HP 497765-B21 memory module is a registered memory module. Registered memory modules use a register to buffer the control signals between the memory controller and the memory chips. This helps to reduce the load on the memory controller and improve system stability and reliability.
Overall, the HP 497765-B21 memory module is a high-performance DDR2 SDRAM memory module designed for use in servers and other high-performance computing systems. It provides a total capacity of 4GB, divided into two 2GB modules, and operates at a clock speed of 800MHz. The memory module also supports ECC and Chipkill technology, as well as registered memory technology for improved stability and reliability. It is compatible with a wide range of HP ProLiant server models and is a reliable and cost-effective solution for mission-critical applications.
