3200 MHz is easy for B450, while A320 struggles with 3000. The only time A320 is really viable is when you're building a home/office PC where performance doesn't really matter, only a working system.
Most B450 boards should even have BIOS updates preinstalled in the factory for Ryzen 3000, if not Ryzen 5000.
Precision Boost and Precision Boost Overdrive depends on the motherboard's voltage regulators to deliver AMD's advertised and expected clocks, and A320 is barely enough to max out a quad-core. It's fine for the R5 1400 or R3 1200, but anything with 6+ cores, forget it, better off with B450.
3200 MHz RAM is ideal for Zen+ chips like the 1600-AF, while Zen chips like the 1600X have a hard time running more than 2933 on most motherboards, and most A320 boards struggle with that as well even with newer CPUs.
Opting for the B450M Pro4 or B450M-DS3H ramps it up to 75 amps which is enough to max out the 65W Ryzen 5 CPUs like the 1600.
If the system loses power while a BIOS update is in progress, it will most likely result in a bricked (dead) board because the BIOS is necessary for the motherboard to actually work with the other components. With a broken/corrupted BIOS, the motherboard can't do anything and becomes useless.
To be safe, it's best to not touch it yourself and let a trained professional handle it since they've been doing it for years.
1. Manual Overclocking support for the CPU and RAM
2. Precision Boost Overdrive support (potentially, depends on board and BIOS)
3. Additional PCi-e 2.0 lanes from the chipset (in case you ever need to add more expansion cards, really)
4. Higher memory support (A320 only supports up to 3200 and often struggles reaching even 3000; 2933 is often the limit which is a problem for newer CPUs, affecting upgradability negatively. B450 boards like the HDV R4 can handle 3200 MHz without problems and potentially higher, like 3600 CL16 which is necessary for 3000 series and newer to get ideal performance)
Ryzen in particular needs faster RAM to perform well because of the Infinity Fabric.
For 1000 and 2000G series, 2933~3000 MHz is ideal, the infinity fabric doesn't benefit from going higher.
For 2000, 3000G, and 1000AF series, 3200 MHz is ideal, going higher has little benefit.
For 3000 and 4000G series, 3600 CL16 is the ideal sweet spot but supports up to 3800 MHz (1900 MHz FCLK)
For 5000 series, 3600 CL16 is also an ideal sweet spot but fabric supports up to 4000 MHz (2000 MHz FCLK)
