Description
The IBM 16R1221 is a specialized 32GB memory kit, comprising four 8GB DDR SDRAM modules in the Micro-DIMM form factor. This kit is specifically designed for IBM systems that utilize the compact Micro-DIMM interface, often found in certain mobile workstations, compact servers, or specialized embedded systems where standard DIMMs are not compatible. Operating at a speed of 266MHz (equivalent to PC2100), these modules provide a respectable data transfer rate for their generation. The CL2.5 CAS Latency ensures timely data access, contributing to overall system responsiveness. The 2Rx8 configuration indicates a dual-rank design, which can offer performance benefits in systems designed to leverage it. This 32GB kit offers a substantial memory upgrade for compatible IBM hardware, enabling enhanced multitasking, improved performance for memory-intensive applications, and support for larger datasets. Its Micro-DIMM form factor is crucial for compatibility, making it essential to verify system requirements before purchase.
