I'm currently using 2x8GB of DDR4-3000 CL16 RAM with my Ryzen 7 5700X on a B550 motherboard. I'm considering an upgrade since most AM4 builds seem to be running at least 3200 MHz, often 3600 MHz. I could add another identical 2x8GB kit to reach 4x8GB of 3000 MHz RAM for around 50-60€, or I could invest in a 2x16GB 3200/3600 kit for over 200€. I've heard that the ideal RAM speed for the 5700X is around 3600 MHz, but I'm curious about the real world performance difference between these options. Can it justify the extra expense for faster RAM?

If you're looking to hit that 32GB mark, I'd recommend going with two 16GB sticks that are at least 3600 MHz. Trying to tune 4 sticks can be a hassle unless you're really into tinkering with your setup. I had my 4x8GB running at 3800 MHz after a lot of fine-tuning, but that took a lot of trial and error!
You can't just throw in any extra RAM. It's best to buy RAM that comes in matched kits. That said, 3600 MHz does tend to be the sweet spot for Ryzen processors. If you do add more RAM, just make sure it's compatible!
I can't give you an exact number on performance gains, but honestly, the difference isn't likely worth the extra cash. For most games and applications, you might see only a slight increase in performance versus your current setup.
Yeah, 3000 MHz is perfectly fine! It's definitely better than just sticking with 2133 or 2400 MHz RAM. If you're not gaming at super high settings or doing intensive tasks, you won't notice much of a difference.
Honestly, you probably won't notice a big difference going from 3000 to 3600 MHz in typical usage, so if saving money is a priority, stick with the cheaper option.

I didn't know that! I thought you could mix RAM sticks. I've got the same CPU as you but with 32GB of RAM; any idea why mine won't go higher than 3200 MHz?
