Memory Kit Rankings (Price vs Performance) January 2017 RAM Rankings.

Welcome to our DDR4 Memory Kit comparison. We calculate effective RAM speed which measures performance for typical desktop users. Effective speed is adjusted by cost per GB to yield value for money. Calculated values don't always tell the whole picture so we check them against thousands of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top Memory Kits. Share your opinion by voting. [RAMPro]
