I had a look at the options with Ryzen 3rd gen but there are no B450 motherboards available for them, and where B450 motherboards are available they are only for 2nd gen Ryzen and on top of that even when selecting a B450 motherboard the max ram speed possible is 2400 Mhz. I would prefer something like 3200Mhz as Ryzen likes fast memory, but I don't want to spend extra on an x470 motherboard that I will likely not need but which are the cheapest option available for Ryzen 3rd gen here on PC specialist.
