I pieced together a machine with the Gigabyte GA-970A-UD3 (Socket M2) (version 1?) with an AMD Athlon II X4 620. I am not sure if I can or cannot update to the new BIOS version. Currently the machine is at Version F3. I am having issue of freeze ups when the machine goes into sleep mode with or without applications running. I have to cold reboot the machine to bring it back up and running.
