I don't know if it's AGPM at play. I tried to enable it for the 670 but just as the desktop should load my monitor shuts off and all disk activity stops.
Obviously I have no idea what's going on with no screen but it's annoying that my card stays locked at 1GHz clock speed because I can't get Kepler power management working.
here on 10.9 dp's, according to HWsensors, my gtx 660ti it stays always in "3D mode" frequency of 914 mhz, in 10.8 when in idle it goes down to 324 mhz... with the same configuration (same dsdt, same macpro 3,1 smbios)...
i've tell the problem to kozlek but he said that it's probably a system configuration problem.... (anyway i'm not sure of this....)
apologize for english
