The HMA451S6AFR8N-TF is a DDR4 SODIMM module crafted by SK hynix, a major player in the global memory semiconductor market. Offering 4GB of memory, it operates at a speed of DDR4-2133P (PC4-17000), providing an ample boost for computing devices through increased bandwidth and higher transfer rates compared to older memory technologies. This module is designed with a 1Rx8 configuration (single rank x8), which denotes it has one rank and utilizes chips that are 512Mx8, ensuring compatibility with a wide range of systems. The 260-pin configuration makes it suitable for laptops and other compact computers that benefit from the smaller form factor SODIMM offers. The 4GB capacity makes it a suitable upgrade or addition for enhancing the performance of entry to mid-level computing devices, improving multitasking capabilities, and supporting smoother operation of memory-intensive applications.
