The AMD Ryzen 9 9950X is a powerful processor, requiring the AM5 socket and DDR5 system memory. The question of which RAM kit is best for this processor depends on how much memory your PC requires. Using more resource-intensive software and games will eat up more RAM, whereas simply watching some videos and typing up documents won’t use much. Windows 11 requires 4GB, though I recommend at least 8GB for normal desktop PCs and 16GB for gaming and creator systems. Here are some of my favorite RAM kits.
