Intel's new 12th Gen Intel Core "Alder Lake" desktop CPUs are bringing the fight back to AMD's Ryzen 5000 chips, with PCIe 5.0 and DDR5 RAM support to boot. The Core i9-12900K is an incredibly potent chip that will no doubt appeal to power users everywhere who need 16 cores for heavy multitasking and specialized work. Like the other 12th Gen chips, the Core i9 supports both DDR4 and DDR5 RAM. The former is more affordable and is readily available, while the latter offers better performance but is more expensive. DDR5 is also currently about as easy to find as the best graphics cards, meaning you might have to wait for stock to level out if you want the latest standard. Nevertheless, this collection of RAM will make a great accompaniment to your new CPU.

Buying enough RAM for the Core i9-12900K

The Intel Core i9-12900K is a beastly processor reserved for those who want the utmost performance in everything from high-end gaming to heavy video editing. If you purchased the new CPU, chances are you're also looking for one of the best motherboards for the Core i9-12900K to go with it. The 12th Gen chips require a new LGA 1700 socket that's not backwards compatible, meaning you will need a new board for this build. This will also split your decision down to DDR4 or DDR5 RAM support, since boards do not offer both.

Some of the best RAM for 12th Gen Intel Core CPUs might look familiar, like the G.SKILL Trident Z RGB DDR4 kit. It's been around for a while, and it has proven itself time and again with its reliability, modest price, performance, and posh look. If you'd rather not yet upgrade to DDR5 due to stock shortages, this is a great way to go.

If you would like to go with DDR5 RAM and can find some in stock, GeIL's Polaris RGB Sync 32GB kit is an excellent choice. It's expensive (when you can find it in stock), but it offers extremely fast speeds, attractive look with RGB lighting, and a lifetime warranty. These kits are generally available in different sizes, so if dual 16GB modules for 32GB total seems like too much, you can always start with a lower amount and work your way up.
