The SUPERMICRO HMT42GR7AFR4A-PB-SM memory module is a high-capacity, low-voltage option for upgrading enterprise-level servers and workstations. With 16GB of DDR3 memory and operating at a low voltage of 1.35V (signified by the 'L' in PC3L), it combines efficiency with performance, delivering a clock speed of 1600MHz (PC3L-12800R). This memory module is designed with a 2Rx4 configuration, indicating a dual rank setup with x4 organization, enhancing overall data throughput and reliability during peak loads. It supports ECC (Error-Correcting Code) for maintaining data integrity by automatically detecting and correcting memory errors, which is essential for mission-critical systems. Moreover, being registered (buffered), it ensures stability and reliability by minimizing the load presented to the memory controller, making it suitable for servers and workstations requiring high memory density and stability. This SUPERMICRO module facilitates significant improvements in system performance and efficiency, particularly in environments that handle large datasets or run complex applications.
