Buying the AMD Ryzen Threadripper 3990X means you're in the business for performance, and to allow the CPU to make mincemeat of any task or gaming you do on your PC, you need some fast RAM. Taking speed, capacity, and price into account, we've rounded up some of the best options. Threadripper supports quad-channel support, so if we recommend a kit with two sticks, buy two of them for better performance.
Corsair makes some fine RAM, and this kit has the clock speed you need of 3,200MHz, which is standard practice for third-gen Ryzen processors. The two 8GB modules are also reasonably affordable when combined together, coming in at around $40 per stick. Pick up two of these kits.
This G.SKILL RAM kit is special. Not only is it 3,200MHz and 16GB in capacity, but it looks amazing. Forget black heat spreaders and say hello to gold. As well as the solid performance and looks, you've also got RGB lighting, which everyone knows adds to available power. Add two of these kits to your build.
If you need to open up 40 tabs in Chrome (you monster), you'll need more than 16GB of RAM to avoid sluggish PC performance. This is where Corsair's 32GB kit comes into play. It's identical to our top pick, but with fancy RGB lighting and four modules.
If we were to make a suggestion...
When looking around for RAM, you need to choose a kit that has a speed of at least 3,200MHz. Faster than this likely won't impact performance when taking value into account but do take note of latency and other factors as two kits are likely not the same. You will also need a compatible motherboard.
We recommend the Corsair Vengeance LPX 16GB Kit (opens in new tab) because it offers excellent value for money with enough speed to keep up with the Ryzen Threadripper 3990X. You can throw in a further two RAM modules to bring your total up to 32GB.
Should you need fast RAM that not only works well but looks great, the G.SKILL TridentZ kit (opens in new tab) is genuinely one of the best-looking RAM kits around, though you'll be paying a small premium for the luxury.
