The difference between 32GB 3200 and 32GB 3600 is negligible, so I wouldn't suggest swapping 32GB for another size. Choosing 8GB sticks is even less attractive since you might end up with slower 1Rx16 cards and miss out on noticeable improvements. Keep in mind that adding more sticks puts extra strain on your CPU's memory controller, which could need more adjustments like voltage and timing settings to maintain stability.
It seems you're questioning your choice of using the same motherboard, thinking it might help later. At the time, you believed extra RAM slots would boost performance and were unsure about DDR5 technology.
It's a reasonable approach. Many users purchase what they require immediately, which would mean acquiring a 2x8 kit and then adding another 2x8 later. Four slot MOBIs are the standard setup. It seems unusual that you're concentrating solely on RAM slots, despite no advantage for performance and no requirement for additional memory. Second-guessing your board because it has four slots rather than two isn't typical. This wasn't an error unless you're experiencing significant frustration with empty slots. Building boards with only two slots can be restrictive, often prompting a RAM upgrade later. It's probably worth exploring RAM options further to better understand the system's capabilities.
It seems this advice hasn't been widely suggested recently, especially for AMD systems where 4x modules face more compatibility issues compared to 2x. In fact, the preferred AM5 boards typically offer only two slots, and it's generally better to stick with 2x even on AM4 to prevent possible complications. Sometimes you can't achieve faster RAM clock speeds with 4x compared to 2x.
