The LENOVO 46W0672 is a 16GB DDR3 Low Power (LP) Registered DIMM (RDIMM) featuring ECC (Error-Correcting Code) to enhance system reliability by automatically detecting and correcting memory errors. This module operates at a speed of 1600MHz (PC3L-12800), offering a balanced performance for legacy servers and workstations that require DDR3 memory. Its 2Rx4 configuration, with two ranks of memory chips, enhances its stability and performance under load. The module's 1.35V operating voltage is lower than standard DDR3 memory (1.5V), which contributes to reduced power consumption and heat production, improving the environmental footprint and operational costs of data centers. CL11 latency of this module strikes a good balance between response time and power efficiency. The LENOVO 46W0672 is specifically designed to work with systems that support ECC RDIMM memory, making it an ideal option for businesses that demand high reliability and performance from their legacy computing infrastructure.
