FM2, those are very old APUs, which one you have in mind ?I am building a custom computer and chosen an AMD Trinity series CPU and dual-channel DDR3 memory. What type of motherboard socket should I choose? FM2,FM2+,FM3,FM3+
Why are you running such an old CPU? You would be better off with a Ryzen 2200G or 2400G and a B450 motherboard.
