Additional Details

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

Infineon Technologies (later Qimonda) was a reputable manufacturer of high-quality memory modules. This module is typically found in servers and high-end workstations requiring stable and reliable memory. The ECC functionality is crucial for applications where data integrity is paramount, such as financial transactions, scientific simulations, and database management. The 'HR' in the part number signifies a specific build or testing revision, which may have further details in archived datasheets from Infineon or Qimonda.
