AMD 11.5b Driver iMac 6750m

Is it now possible to install the 11.5b catalyst

on boot camp?

iMac 2011 with AMD6750m

Can someone check the original Core Speed ​​of ATI 6850m please?

The core speed can be seen as the hardware settings in the Catalyst menu.

If you prefer to take the original Boot Camp drivers?

Thank you for your effort
