The speed supported that is quoted for a motherboard or processor is the speed at which the ram will boot into the bios.
Once in the bios, for ram to operate faster than stock it needs to be overclocked.
The better ram kits will be capable of this.
The settings will be embedded in the ram kit itself and defines the combination of speed, voltage, and timings that the manufacturer has determined will work properly.
There may be more than one set of settings.
XMP is an intel term, amd has something equivalent called EXPO.
Invoking XMP or EXPO is a motherboard short hand to extract the settings from the ram stick and apply them to the ram settings in the motherboard. Otherwise, you do the settings yourself in the motherboard ram settings.
You are on your own to go higher. This will certainly include running the ram at much higher voltage than the settings for 3200 speed.
Will it work... Posslibly.
Will it damage your ram... Possibly.
Will such an overclock work reliably.... Possibly. Run memtest or such for a full pass with NO errors.
Will such an overclock result in a noticeable benefit in performance... Possibly. Only you can tell what is significant.
