W670RC bios update

Hi there,
Could you advise if my bios is up to date, and if not, please advise where I can find the latest revision? I’m looking to upgrade my HD in the near future and I’d like to start with the latest bios.

PC: W670RCQ1
BIOS Version/Date American Megatrends Inc. 1.05.14, 31/03/2016


Anyone able to advise? Thanks
