Cat 8.9 shows GPU Clock set at 750 and the GPU Clock Current is 500. the default core is always stable in the CCC at 500 when using GPU-Z.0.2.8 the core is stable at 500 But when using RT v2.11 the core freq is changing between 500 and 750, and this also causes GPU-Z.0.2.8 to change. When I exit RT then the changing in GPU-Z.0.2.8 stops. Weird? Any ideas? If I am in a 3D app then the core is stable at 750.
