RAM can often be overlooked. Simply buy any kit that fits in the slots, and you're good, right? Wrong. The AMD Ryzen 7 3800X needs fast RAM. Sure, you could get away with slow modules, but you'd lose out on performance, which is why we rounded up these RAM kits for the CPU.
16GB of RAM is recommended for most consumers, but if you find yourself running out of system memory, you'll need to look at adding additional capacity. This 32GB kit from Corsair is the same as our top 16GB listing but has double the amount of memory available.
