The HYS72D128020GR-7-A is a 1GB DDR2 ECC Registered DIMM (RDIMM) from Infineon Technologies (now part of Intel). It is designed for server and workstation environments requiring high reliability and data integrity. The ECC (Error-Correcting Code) feature corrects single-bit errors, which is crucial for maintaining system stability. Being a Registered DIMM (RDIMM) it includes a register that buffers the address, command, and control signals, reducing the load on the memory controller, and allows for higher density and improved signal integrity in server environments.

Applications:

• Servers: Used in server systems to provide high-capacity and reliable memory for demanding workloads.
• Workstations: Suitable for high-performance workstations running memory-intensive applications like video editing, 3D rendering, and scientific simulations.
• Data Centers: Deployed in data centers to support virtual machines, databases, and other critical applications.

Features:

• 1GB Capacity: Offers a significant amount of memory for multitasking and running memory-intensive applications.
• DDR2 Technology: Utilizes DDR2 SDRAM technology, providing faster data transfer rates compared to DDR.
• ECC (Error-Correcting Code): Detects and corrects single-bit errors, enhancing data integrity and system stability.
• Registered DIMM (RDIMM): Reduces the load on the memory controller, enabling higher module densities and improved signal integrity.
• DDR2-800 (PC2-6400): Supports a memory clock speed of 800MHz, providing high bandwidth for data transfer.

Benefits:

• Increased System Stability: ECC functionality ensures data accuracy, preventing system crashes and data corruption.
• Improved Performance: The higher clock speed and registered design contribute to faster data access and overall system performance.
• Higher Memory Capacity: Allows for running more applications simultaneously and handling larger datasets.
• Enhanced Reliability: Designed for use in demanding environments, ensuring consistent performance and long-term reliability.
