Hey there grassy!
🙂Well, if it's not broke don't fix it is a good maxim with the BIOS. That said the new BIOS might have something you want....
If you do update, via the OS (internet) is not a great way to go.... BIOS flashback Great.... or EZ flash in the BIOS good too...
Your board has 2 BIOS chips...so, if you are good as you are, you can copy BIOS 1 to the second chip and have that as a backup (test it works after the copy) so you can go for it on the other chip....you always have a fail safe if you manage things well;)
