The LENOVO 90Y3178 memory module is designed to enhance the performance and reliability of Lenovo servers and workstations. This module provides 4GB of memory, which can significantly improve the ability to multitask and handle data-intensive applications. It operates at a speed of 1600MHz, ensuring fast data access times and improving system efficiency. The module's ECC (Error Correcting Code) functionality detects and corrects data errors in real-time, increasing system stability and reliability. It has a CAS Latency (CL) of 11, balancing performance and latency to provide responsive operation. The module uses 1.5V, making it compatible with many systems while maintaining energy efficiency. A 2Rx8 configuration means the module is dual-ranked and has eight banks of memory chips, which can improve module density and performance. As a Registered DIMM (RDIMM), it includes a register that delays all information transferred to the module, allowing for a more stable and reliable memory environment, especially in systems with high memory capacities. The low-profile design of this RDIMM makes it ideal for use in space-constrained environments without compromising its performance. Tailor-made for use in Lenovo systems, this memory module ensures compatibility and a smooth upgrade path for users looking to enhance their system's capabilities.
