You are not using Wattman controls correctly. All the third party graphics controllers conflict with Wattman settings. The slider under temperature say "Max" and "Target"...which is where you are screwing up. Substitute the word "Minimum" for the word "Target" and you are reading it correctly. That setting must remain at 45c....as it has always been ever since this was introduce in the HD6970 graphics card. And it wasn't ever changeable.
If you want to delete all the controller apps and use Wattman then this will help.
Delete any controllers, not disable...delete. (Trixx, Asus, Afterburner, etc,etc) Before deleting them, use the 'return factory defaults" first..to repair any changes to the registry.
Clean install the driver of your choice > Clean Install AMD Graphics Drivers
In the Control panel/ global set the Power Limit to +50. Click apply that will appear at the top of the page. Change nothing else.
Go the the "Gaming" section of the control panel, select a game/Wattman profile..and change one thing only. Change the Temperature to Manual and set the MAX temperature to 80c. Leave the other slider at 45c. Click apply.
Play a game. Run Hardware monitor in the background. Check the readings after you finish playing.
Included are my results after a hour or so of playing BF.
i'll give it a try!
thank you very much
