Description
This 1GB DDR3 UDIMM from Micron, identified by SKU MT9JSF12872AY-1G1D, is a standard memory module suitable for a wide range of computing applications, including desktops, workstations, and entry-level servers. It operates at a frequency of 1066MHz, which was a common speed for DDR3 memory, offering a balance of performance and compatibility. The module features a 1Rx8 rank configuration, meaning it has a single rank of memory chips, each with an 8-bit data width. This is a typical configuration for lower-capacity DDR3 modules. The CAS Latency (CL) of 7 indicates the number of clock cycles required for the memory to respond to a data request, providing a relatively quick response time for its speed class. As an Unbuffered DIMM (UDIMM), this module does not include a register chip, which places a direct load on the memory controller. This makes it suitable for systems with a limited number of memory slots or where the memory controller can handle the direct load. It does not feature ECC (Error-Correcting Code) functionality, making it ideal for non-critical applications where the overhead of ECC is not required. The MT9JSF12872AY-1G1D is a cost-effective and reliable choice for basic system memory needs or for upgrading older systems.
