    HP Pavilion dv6 switchable driver issue (radeon 6520g + radeon 7690m)



           Notebook - HP Pavilion dv6-6c33er (Windows 7/8/10 [problem was tried to solve on all of this versions])

           Integrated GPU - radeon 6520g

           Discrete GPU - radeon 7690m

           CPU - AMD A6 3430MX

           RAM - 6GB



           Getting BSOD while windows sturtup

           Problem caused by a file atikmdag.sys (0x0000003B error number)

      Evidently problem caused by switchable driver because with switched off one of graphic adapters windows could start.. same with standart VGA driver.


      Tested solutions:

      on Windows 7:

      Fully reinstalled Visual C++ Redistributable and NetFramework

      1. a) ALL AMD drivers deleted with DDU utility (in Safe Mode)

          b) Installed Crimson Edition 16.2.1 Beta


      2. a) ALL AMD drivers deleted with DDU utility (in Safe Mode)

          b) Installed switchable drivers from HP website HP Software and Driver Downloads (dv6-6c33er)


      3. a) ALL AMD drivers deleted with DDU utility (in Safe Mode)

          b) Autoinstalled Microsoft drivers



      on Windows 8 were done all points such as Windows 7 (BSOD on each)


      on clean Windows 10:

      Autoinstalled Microsoft drivers (all other variants is not suitable here as I understood by reading the forums)



      Q: Why you couldn`t disable integrated graphics?

      A: There are no Fixed mod in BIOS sittings and there are no any other BIOS firmware with this option.


      Q: Why you can`t install driver just for discrete GPU?

      A: It is not working because i haven`t got single videodriver (AMD, Microsoft and HP provide only switchable for this platform) and i dont want to lose power save notebook mode which use integrated GPU..

          Win7......ALL 'critical' , 'recommended', and relevant 'optional' updates must be installed before any attempt to install any AMD driver. Not just the ones you mentioned.

          Win8...not supported by Microsoft or AMD

          Win10...not supported with drivers from AMD. You must use the drivers furnished by Microsoft Update. There are no drivers supporting that APU from AMD.


          The following AMD APU products with AMD Radeon™ Graphics support up to WDDM 1.2 and DirectX® 11 on Windows 10:

          • AMD A4/A6/A8-3000 Series APUs
          • AMD E2-2000 APU
          • AMD E1/E2-1000 Series APUs
          • AMD E-200/300/400 Series APUs
          • AMD C-Series APUs
          • AMD Z-Series APUs

          NOTE: These APU products must be installed only using the display driver version available via Windows Update. If you have upgraded to Windows® 10, please DO NOT install the AMD Catalyst™ Driver. Instead, enable Windows Update and allow it to detect and install the appropriate driver. If you have already upgraded to Windows® 10 and installed the AMD Catalyst™ Driver, please follow the steps listed below to resolve this issu

          1. Uninstall the AMD Catalyst™ Driver using the Program and Features option in the Control Pane
          2. Reboot the system
          3. Use Windows Update to install the appropriate graphics driver for the APU.
