Tested yesterday the board with 2 qx9775 and the last bios available

Using qx9775 it unlock vcore option to 1,6 but I think the bios is no perfectly compatiible with the QX cpu because if I change the vcore valu from "auto" o any other value, afther i reboot the bios automatically set the vcore value on 1,6 volt and it shows jsut 2 option: "auto" and "1,6" volt.
If I set again on "auto" afther reboot I can see again all the option available from "auto" to "1,6"

this is really strange, I'll try to ask support to some asus engegnieer
