No, you can't use faster RAM than what your processor supports. The speed is limited by the chip itself.

I understand if this was previously asked; after checking the forum, I couldn't locate a relevant discussion. I’ve been building and selling PCs as a teenager, but I haven’t done much PC assembly in the last couple of decades. Intel’s specs say your i5-10400 can support RAM up to 2666MHz, while your motherboard claims up to 2933MHz. Recently I saw videos showing people using i5 CPUs with B-series boards and even higher RAM speeds (3200MHz+). Could my CPU limit the performance if I upgrade to faster RAM? Are there other parts that could make better use of higher-speed memory? Your question is appreciated!
For a B or H series board, your RAM must match the maximum speed shown on Intel’s site, which is 2666 MHz. With a Z series board, you can exceed that limit and use faster RAM than the CPU specifies.
Consider watching the entire video prior to making your purchase decision.
Thanks for the clarification. It really helped understand how the processor limitations connect to RAM speeds. I was already aware it couldn't be overclocked, which means a Z-series board wouldn’t work well, but I wasn’t sure about the full picture. I’m not aiming for a high-end gaming rig—most of my games are older and don’t need top performance—and I want to keep costs down. That’s why I’ll stick with the 10400. I’ll also avoid buying RAM faster than 2666MHz. Appreciate the insight!
