CPU UPGRADE

[Edgar2142]

Hello, recently I have decided that I want to upgrade my CPU from Athlon II X4 645 to FX-8320E.
I saw the Motherboard CPU list support however, I did not find FX-8320E there.
Does it mean that the processor will not work with my current motherboard at all?
my Motherboard: GA-880GM-USB3 (3.1)

It means you will need a 990 chipset board for this CPU - if the CPU is not listed the board bios will not contain the specifics of this CPU.
