Your secondary rig is getting a performance boost (3200G to 4650G) and you're thinking about boosting the memory. The issue is that there isn't a compatible memory QVL for your motherboard (B450I Aorus Pro Wifi ITX) with Renoir. Both Matisse and Vermeer lists say the max supported is 3600MHz, but your current pick is a 2x8 3600C16 which appears on Vermeer's list. Will it work out of the box with your 4650G, or should you opt for a 3200MHz C16 instead?
The probability is high. You'll seldom face problems with RAM up to 3600MHz on Ryzen.
either 3600 or 3200 works, but 3200 is more certain to function or you might return the chip. 3600 should probably work, though some CPUs may not handle it well. Performance differences might be more noticeable on an APU if you use the integrated GPU.
