The LENOVO M393B5273DH0-YH0 represents a 4GB DDR3 Registered ECC memory module, specifically designed for compatibility with a range of Lenovo servers. Operating at a frequency of 1600MHz (PC3L-10600R), it provides a significant boost in data processing and transfer speeds, vital for server operations involving large datasets and demanding applications. The module is constructed with a 2Rx8 configuration, signifying two ranks of memory arrays for enhanced parallelism and bandwidth. The 'L' in PC3L denotes it as a low-voltage module, operating at 1.35V, which reduces power consumption and heat generation, benefiting the overall efficiency and longevity of the server system. The inclusion of Registered ECC (Error-Correcting Code) technology is a hallmark of enterprise-grade memory, ensuring data integrity and system stability by automatically correcting memory errors, which is paramount for servers tasked with critical workloads.
