Additional Details

The HYS72T128000HR-3S-A module is specifically designed for systems supporting DDR2 ECC Registered DIMMs. It operates at a standard DDR2 voltage of 1.8V. The registered design includes a register between the DRAM and the system's memory controller, which reduces the load on the memory bus and enables higher densities and speeds. The PC2-5300 rating indicates a maximum bandwidth of 5300 MB/s. The module employs a 240-pin DIMM connector.

Infineon Technologies (later Qimonda) was a reputable manufacturer known for producing reliable memory modules. This module is commonly found in servers and high-end workstations where memory stability and data integrity are essential. The ECC functionality is critical for applications where data accuracy is paramount, such as financial transactions, scientific simulations, and database management. The 'HR' designation indicates a specific build or testing revision. The 'A' likely indicates a minor revision or variation within the production process.
