Product Description
The Infineon HYS64V16220GU-8-C is a 128MB SDRAM module operating at a frequency of 100MHz, identified as PC100. This type of memory predates DDR technology and was common in computers from the late 1990s and early 2000s. It is a Non-ECC (Non-Error-Correcting Code) module, meaning it does not have built-in error checking capabilities, making it suitable for standard desktop and workstation use where data integrity is managed by the system or not critical. This module is a URDIMM (Unbuffered DIMM), which means the memory chips are directly connected to the memory controller without an intermediate register. This configuration is typical for consumer-grade systems and offers lower latency compared to registered modules. The operating voltage is 3.3V, standard for SDRAM. The CAS Latency (CL) is CL2, indicating a fast response time for data access, which was desirable for performance in its era. The HYS64V16220GU-8-C is designed for systems that specifically support 100MHz SDRAM DIMMs. Its 128MB capacity is modest by modern standards but was significant for the time. It is crucial to confirm motherboard compatibility regarding memory type (SDRAM), speed, voltage, and form factor before installing this module, as it is not compatible with DDR or later memory generations.
