Yes, I do checked the supported CPU list on the official gigabyte website. but it only shows FX- 6120. And yes, I do update for the BIOS. And what happen if I ignore it and just upgrade to FX6300?
I have a ga 68mt-s2 rev 3.1. It should work since it has a am3+ socket and it says to update the bios in order to use to it. The amd fx 4100 is an am3+ and it works fine.
