Factors to Consider When Choosing RAM for Core i9-9900K

The Core i9-9900K processor is a high-end CPU designed for demanding tasks such as video editing, 3D rendering, and gaming. To get the most out of this powerful CPU, it’s essential to choose the right RAM. Here are the factors to consider when choosing RAM for Core i9-9900K:

When selecting RAM for the Core i9-9900K:

Speed: It supports DDR4 RAM up to 2666 MHz, but higher speeds like 3000 MHz or 3200 MHz can enhance overall performance.

Capacity: It supports dual-channel DDR4 RAM with a max capacity of 128 GB (64 GB per channel). For most users, 16 GB or 32 GB is sufficient.

Timing: Lower latency (measured in nanoseconds) is better. The key is CAS latency (CL), where a lower number means better performance.

Compatibility: It’s essential to choose RAM that is compatible with the Core i9-9900K and the motherboard. DDR4 RAM is backward compatible, meaning you can use older DDR4 RAM with the Core i9-9900K. However, the RAM must be compatible with the motherboard’s chipset, and the motherboard must support the RAM’s speed and capacity.


It’s worth investing in high-quality RAM for the Core i9-9900K processor to ensure that the system runs smoothly and delivers the best performance possible. Furthermore, with proper overclocking techniques, users can push the RAM to its limits and unlock even more performance, but it’s essential to be careful and aware of the risks. Overall, choosing the best RAM kit for Core i9-9900K is an essential step towards building a powerful and high-performance PC.
