    Crimson 16.12.1 underclocking memory speed

      Memory Type - GDDR5

      Memory Clock - 1250 MHz

      Core Clock - 947 MHz

      Radeon Software Version - 16.12.1

      Until 16.12.1 I had a stable system with GPU overclocked at 1040MHz and memory speed underclocked at 1235MHz.

      Now moving from 16.11.2 to 16.12.1 , the system is extremely unstable and practically useless which is caused by the 'new' Wattman software replacing GPU overdrive.

      It seems in the user interface, I just cannot underclock the memory speed. It is reset to the factory minimal 1250Mhz and can only be overclocked.

       

      It is insane if you cannot underclock memory speed. I absolutely need to be able to move back to max 1235MHz at any voltage and GPU speed.

      Can someone give instructions how to establish with Wattman an underlocked memory speed.

      If this is a software design flaw, please fix in next release.

      BTW no ReLive ever installed.

          At this point in time, Wattman does not support memory underclocking .

              Thanks for the info, Ray.

               

              For the moment I downgrade to 16.11.2 which is working absolutely fine for my situation.

              I just hope the AMD Engineering wizards will address this memory speed issue in future releases....

               

              (As it seems, I have more or less been duplicating the question about this subject. Sorry for that)

              I am also hoping that underclocking will (again) be possible in a future AMD driver. See my thread here: Downclocking with AMD Wattman

               

              I need this feature to let my 290X (with Elpida memory) run stable. When can we expect this feature in AMD Wattman ray_m amdmatt ?

                I have same problem, and original topic include not real solution and closed now. I tried MSI Afterburner too for memory underclocking to 1100 MHz (this is a stable frequency for my card), but I get blank screen after save settings.

                 

                I have an R7 260X card with this hardware:

                I NEED REAL underclocking system for my card IN WATTMAN!
