    Some progress on Flickering diagnostic Firepro W4100


      I have the frequently described problem of flickering but I have made some progress on the diagnostic.


      The configuration:

      - AMD Phenom II X945

      - AMD FIREPRO W4100

      - Windows 10

      - AMD Catalyst 2015.1104

      - Driver 15.201.2401.0

      - Monitor Dell U3415W. Connected DP1.2 3440x1440


      The problem:

      flickering happen immediately when the mouse is moved, when the graphic load is very low.

      The problem disappear as soon as a 2nd monitor is connected



      the memory clock is at 150MHz (Using GPU-Z) when the computer idle and as soon as am action increase graphicload, frequency goes up, it is when the flickering start.

      When a second monitor is active the memory frequency stays at 1000MHz, and in that case no flickering.


      My question:

      How can I ensure that the memory clock doesn t fall at 150MHz?

      There is no Overclocking option on Catalyst.
