What you want to do is look at your motherboard and see if everything is running ok and there are no issues at all with anything. Then go to the Gigabyte web site and look at the bios updates that are above the one you have and see if any of then say that they will give you any improvement over what you have.
Some bios updates will fix a certian function while other will enable more selection of memory or improve sata funtionality. So you should check out the bios updates to see if anything will improve what you now have because they do tell you to update the bios only if you are haveing problems.
