I wonder if it is safe enough to update BIOS with Gygabyte @BIOS update utility did any of you have any experience,good/bad with this?
Thanks

I have never used it but I was wondering why you want to update. Do you have a specific problem or is it just to have the latest version?

If its not to address a problem or security issue, I would not update.

BIOS updates and router firmware updates are two areas to avoid unless you are having a problem, and then its only after you have eliminated all other causes.
