Product Description

The Samsung 256U8S1616-8KM is a 256 Megabyte (MB) Synchronous Dynamic Random-Access Memory (SDRAM) module designed for use in desktop computers and workstations that support PC100 memory standards. This module operates at a clock speed of 100MHz, providing a balance of performance and compatibility for systems of its era. The Unbuffered DIMM (UDIMM) form factor, with its 168 pins, is standard for many older motherboards, and it requires direct memory controller access without intermediate buffering. This memory module is specified as Non-ECC (Error-Correcting Code), meaning it does not have the built-in error detection and correction capabilities found in ECC memory. This is typical for consumer-grade or entry-level server memory where the cost-saving outweighs the need for advanced data integrity checks. The module operates at a standard voltage of 3.3V and features a CAS Latency (CL) of 2, indicating the number of clock cycles required to access data after a command is issued. Lower CAS latency generally translates to faster response times. The 256MB capacity is relatively small by modern standards but was common for systems manufactured in the late 1990s and early 2000s. This specific module is suitable for upgrading or replacing memory in older systems that require PC100, Non-ECC, Unbuffered DIMMs. Compatibility should always be verified with the motherboard's specifications before purchase.
