It shouldn't be a problem as BIOS updates are usually backward compatible and just have "added support" for whatever hardware.
When you update the BIOS, follow the update instructions exactly and don't have anything else running (e.g. browser or e-mail) so as to not interfere with the BIOS update. Keep in mind a failed BIOS update can corrupt the BIOS and unless your motherboard has a BIOS recovery option, worse case it can require a motherboard replacement.

I did assume it would be backwards compatible. I just wanted conformation on that. Also I forgot my MOBO does have a BIOS recovery option. I have @BIOS that came with my mobo. When I run @Bios it only indicates one choice to download and it's the F5 that already installed. I may need to update @Bios. I have notices several BIOS ver. newer than F5. Gigabyte also has a download utility that scans the mobo for updates and it reports all up to date.
Is there any reason to use the i7 3770k in a Z77 board instead of the one I have Z78?
