The LENOVO 90Y4580 is an express-class 8GB DDR3 memory module engineered to enhance the performance and efficiency of servers and workstations. This module, with its 1.35V operation, offers a balance between high performance and lower power consumption. Operating at 1333MHz (PC3-10600) and with a CAS Latency of 9, it provides a responsive and smooth computing experience. The '2Rx4' configuration signifies a dual-rank setup, optimizing the density and performance of the memory module. The ECC (Error-Correcting Code) feature is designed to detect and correct data corruption, ensuring the reliability and stability of critical systems. Its VLP (Very Low Profile) RDIMM form factor makes it an optimal choice for systems with constrained space, including low-profile servers and workstations. The LENOVO 90Y4580 is tailored for systems that demand high-speed, reliable memory, offering a significant upgrade in performance with the added benefits of error correction and reduced energy usage.
