The LENOVO 90Y3157 module offers a substantial 16GB of memory, making it an excellent option for server upgrades that require high-density RAM. This Very Low Profile (VLP) Registered DIMM (RDIMM) utilizes ECC (Error-Correcting Code) technology to ensure data integrity and reduce system crashes, making it ideal for critical applications and environments. It operates at a voltage of 1.5V, conforming to DDR3 standards, which ensures compatibility with various server systems. The memory operates at a speed of 1600MHz, falling within the PC3-12800 classification, which is suitable for handling demanding applications and multitasking. The CL11 (Column Address Strobe Latency) signifies the delay time between the moment a data column is accessed and when it's available for tasks, balancing performance and power efficiency. It is specifically designed to meet the needs of next-generation servers and computing systems, ensuring smooth operation and improved system reliability. With dual rank (2Rx4) configuration, this memory module is built for stability and high performance, making it an excellent choice for businesses looking to expand their server's memory capacity while maintaining robust data integrity.
