The LENOVO 00D4959 is an 8GB Low Profile (LP) Unbuffered Dual In-Line Memory Module (UDIMM) offering a substantial upgrade to the performance of IBM server systems. Operating at a frequency of 1600MHz, this memory module complies with the PC3-12800 specification and integrates Error-Correcting Code (ECC) to ensure the reliability and integrity of data processing, which is especially valuable in server and critical computing environments. Its 2Rx8 double-rank architecture enhances signal integrity and performance over single-rank modules. With a voltage requirement of 1.5V, it provides an efficient balance between energy consumption and computational power. Designed for compatibility with select IBM servers, this ECC DDR3 memory module is an ideal choice for server administrators looking to boost system capabilities, enhance multitasking, and ensure faster data processing in demanding computing environments.
