Hello everyone, this might seem a bit unusual, but I'm discussing the best choice for 4K gaming. My setup includes a 75-inch 4K Samsung TV with a 120Hz refresh rate. I plan to upgrade my memory next. Currently, I'm using a Ryzen 5900X with an RTX 3080 Ti. Since I have an ITX form factor system with only two RAM slots, I'm considering whether 32GB DDR4 3600 CL14 or 64GB DDR4 3600 CL18 would perform better. It looks like I can't find a dual-channel 64GB DDR4 3600 CL14 option.

Storage size doesn't determine speed.

RAM becomes more useful when you actually rely on it. When you're not using more than 32GB—especially during gaming—64GB won’t significantly boost performance. What really counts is speed. A 3600MHz CL14 chip offers the highest XMP rating for Ryzen 5000 models, making it quite efficient. If you're planning a high-end build with top-tier DDR4, aim to push it beyond stock speeds; the timing on the XMP profile tends to be poor, and that kit likely can reach around 3800MHz CL14, which is close to its daily maximum on a 5900X.
