This is a guide I just found off the Windows site for explaining their own driver, yet guess what the same drivers registry are used by AMD where the compatibilities with Windows Power Now function needs switching on properly in the registry.
Else you have AMD's driver doing its own thing with Power Now and Windows unaware, thought something seemed strange.
Quote:
10. Start Registry Editor (Regedit.exe).
11. Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\System\CCS\Services\AmdK7\Parameters
12. On the Edit menu, point to New, click Dword Value, and then add the following registry value:
Value name: HackFlags
Radix: Hexadecimal
Value data: 1
A value of 1 enables the legacy Power Now! interface. To disable this feature, set the data value to 0.
13. Quit Registry Editor.
14. Restart the computer.
You don't need windows drivers, which are out of date (at beginning of list of instructions), you need AMD newest, yet still check the setting to 1 in registry edit will make Windows see it has that feature, else to me it has appear to half work and slower as the AMD would fire up fans, yet Windows would take ages to reassert where it was in the picture.
Anyways just done so and thought should tell everyone as clearly either AMD or Windows should have that on as standard, not off??
