I've been curious about whether my gaming setup is facing any performance issues, particularly when playing CPU-intensive games. I've heard that AMD processors, like my Ryzen 9 5900x, may suffer from lower RAM speeds more than Intel ones. Here are my specs:
- CPU: AMD Ryzen 9 5900x
- GPU: RTX 5070ti
- RAM: X2 Kingston 4096MB 2133 MHz and X2 Corsair 8192MB 2133MHz.
Thanks for any insights!

Yeah, 2133MHz is pretty slow. Make sure you actually bought that speed. Sometimes you need to enable XMP in your BIOS to unlock the real speeds of your RAM.
2133MHz is really low for Ryzen! If you haven’t already, you should definitely check if XMP is turned on. Your RAM might be running at stock speeds, which can be a performance bottleneck.
Absolutely! For Ryzen 5000 series, it's best to use RAM that's at least 3600MHz CL18 or ideally CL16. Using 2133MHz RAM can significantly hinder the performance of your Ryzen chip in demanding scenarios.
