AMD's A10 APU's were using FM socket, it was quite lackluster when it was introduced in 2011 and lacked both in CPU and GPU performance.
It used to be decent for low power desktop/gaming situations with tight budget but past that.. was kind of lacking.
Since it's old and the development for new processors for FM slot has ended, it never got DDR4 support.
Now.. if it's the more recent A10 9700 (7th gen) then it uses the modern AM4 slot and supports DDR4 and.. pretty much any AM4 motherboard with A320 series or better chipset should support it.
The big question is.. as bmockeg said, which A10 Apu?
