The DELL HMT42GR7MFR4C-PB memory module is a high-performance 16GB DDR3 RAM stick designed specifically for servers and workstations that require reliable and fast memory solutions. Operating at a speed of 1600MHz, this dual rank (2Rx4) memory module ensures that data flows swiftly and efficiently between the RAM and the processor, minimizing lag and improving the overall performance of your system. This RAM module is built with a PC3-12800R specification, which means it has a theoretical bandwidth of 12.8GB/s, providing ample speed for most demanding applications and workloads. It features ECC (Error-Correcting Code), a critical feature for enterprise and scientific computing where data accuracy is paramount. The register (buffered) nature of this memory module further enhances stability in systems with multiple memory modules by acting as a middleman between the DIMMs and the memory controller. Its compatibility with Dell servers and workstations is assured, making it an excellent choice for upgrades or replacements within Dell systems to ensure optimal compatibility and performance.
