Hi all
I've got an unknown device on device manager

ACPI\PNP0A0B


which is not found anywhere through windows update or searching through the driver cd

I've done a google search and it appears that some users installed the Intel Turbo Boost Max Technology 3.0 but it is not valid for our Z170 m/b I think

https://downloadcenter.intel.com/download/25994/Intel-Turbo-Boost-Max-Technology-3-0?v=t

So has anybody found a solution?

Thanks

P.S. You have to force to show hidden devices in Device manager for the acpi unknown to appear.

Yes thats it but I have ai suite 3.0 already installed...shall I reinstall it from the beginning? Have you solved yours this way?
A new version of.ai suite will come out soon which fixes a prob with the nvidia drivers of strix gpu cards so will wait for this
