I'm planning to upgrade my PC and I'm hoping to reuse my current RAM. Right now, I've got a 6th Gen Intel i5, 32GB of 2133MHz DDR4 RAM (2x16GB), a GTX 1060 GPU, and a B150M motherboard. My system was originally built for casual gaming but has turned into a workstation for tasks like GIS and photogrammetry. I'm on a budget and thinking about upgrading my CPU, possibly to an i7 7700 or jumping to a newer AMD setup. However, I'm worried about the 2133MHz RAM being a bottleneck for a new CPU. If I get a motherboard that supports faster RAM, will my slower RAM still work, and will it choke my CPU's performance?

Yes, you can absolutely use DDR4-2133 RAM in a DDR4 motherboard. While the slower RAM may limit top performance, it will function until you're ready to invest in better speed. Just know that an upgrade to higher speed RAM would give you better overall performance in tasks that depend on memory speed.
Most DDR4 RAM is overclockable, so you might not hit the 3200 MHz speeds, but you can push it a bit more than 2133 if your motherboard supports it. Just be cautious when overclocking for stability!
Your RAM will work but a higher-speed option will give better performance. If you're upgrading to a new CPU, keep in mind that while your current RAM holds back a bit compared to what's possible with faster RAM, it's definitely a solid first step to upgrading.
Your 2133MHz RAM will work perfectly fine with newer CPUs, so compatibility isn't an issue. However, you might see some performance limitations since slower RAM can hold back the full power of a faster CPU. Even with 2133MHz, any new processor will be much better than your current setup. Just keep in mind that if you go with an AMD Ryzen, they can be more sensitive to RAM speeds compared to Intel. The upgrade will definitely be worth it, though!
