    R9 295X2, 300MHz clock locked


      Yeah so after upgrading to crimson 300MHz all 4 GPUs...


      flashed MB BOIS - nothing changed

      MSI Afterburner - nothing changed

      disabled ULPS - nothing changed

      disabled powerplay - nothing changed

      reinstalled windows 10 - nothing changed

      progressively went back driver releases - nothing changed even back to 15.7 (also used a AMD software remover linked by an AMD empoloyee)

      reinstalled windows 8.1 - nothing changed

      progressively went back driver releases - nothing changed

      went back to windows 10 and latest drivers - nothing changed (didnt think it would)

      used Clock Blocker - finally something Master GPUs on the cards clocked up by force

      ran benchmark again - master GPUs started kind of clocking for the first 5 seconds then back to 300MHz....

      Last ditch effort flashed GPU BIOS - samething nothing clocks...


      Crimson has bricked my vary vary expensive GPUs... If anyone wants a good laugh here is my neutered beast machine in action: AMD Radeon R9 295X2 video card benchmark result - Intel Core i7-5960X,Gigabyte Technology Co., Ltd. X99M-Gaming 5



        • Re: R9 295X2, 300MHz clock locked

          Please uninstall MSI Afterburner and any third party applications that are used to control GPU clock speeds and fan controls.


          Download and run DDU. Follow the prompt to restart in safe mode and click Clean and Restart.


          Download and install Catalyst 15.7.1 WHQL available here. This should should resolve the clock issue for you. Furthermore, you may be able to use Catalyst 15.11.1 Beta available here.


          There is an issue with Crimson and fluctuating core clocks which is under investigation at the moment. We apologise for any inconvenience caused.

              Thank you for the response I've done that already. as stated above... Core clock fluctuations would be welcomed right now, its staying at D2 constantly even with going back to previous pre-crimson drivers. The only way I got it to start working on the 295's master GPUs was with clock blocker but the slave GPUs will not clock properly. After I ran clock blocker the master GPUs will clock up to D3 even with clock blocker shut off...
