z170 gaming k3 and f20 bios - 6700k speedstep values

[dertysweet]

Just updated to f20 on a z170 gaming k3 and my 6700k no longer gets down to 800mhz 8x100 in idle. It only gets as low as 1200 1300mhz. Also voltage is only 0,800v. In f3h system was automatically dropping to 800mhz and 0,2 0,3vcore.
How can i solve that?!
Speedshift and voltage optimisation are enabled.

All I can say is go through the forum here and read all the people that are having problems with F20. So if you want to down grade there is thread that will tell you how to that. http://forum.giga-byte.co.uk/index.php?topic=17957.0
