Latest Windows 10 drivers update forcing to update our rig bios to 2.4.1.

As well as 2.3.1, this version provides up to 20% drop in performance!

Check you BIOS version, and roll back to 2.1.1 (fastest one, but a bit loud by fans) or 2.2.1 (-5% to 2.1.1, but more balanced) if you need you gear working at full throttle.
