R3 2200G, without a graphic card. Do you think this RAM can handle 3200MHz? https://www.bukalapak.com/p/komputer/hardware/hard-disk-ram/j402y1-jual-ddr4-8gb-2x4gb-2666mhz-kit-cl-16-18-18-35-purple-ram-gaming-overclock-tsunami-v-gen?utm_source=apps
Since you're wanting a 2nd-gen Ryzen CPU, you should get a B450 motherboard to ensure compatibility out of the box. If you go with a 300 series AM4 motherboard, you should end up with a motherboard needing a bios update and no compatible CPU to administer the update.
I would not get that RAM hoping for 3200MHz. It's already got a relatively high CAS Latency of 16, so it would likely have to increase to 18 if it could even run 3200MHz. That's pretty high CAS. Lower CAS means faster timings.
You can get 3200MHz RAM and run it at 2666MHz if you wanted or needed.
