If it works, don't fix it.

I have not touched bios since F3L nor tested versions since then if you get my drift

Only reason you should update beyond that is to unlock cores with F3K if thats your thing.

I would only be updating if your having a problem and there is a bug fix in a later bios adressing that problem.

UPDATING VIA WINDOWS SOFTWARE AND + OVERCLOCKED IS A BIG NO NO!
