Just to copy/paste in the event that post ever gets deleted or something:


Further reading of experiences around the AGA in this and other forums, made me even try the plug and unplug technique proven to work by some users with the 3000 series (https://www.dell.com/community/Alienware/PCI-e-3-0-x4-for-ampere-3080-3090-question/m-p/7894720#M43691), however I had no luck until I did the following:

  • Uninstalled AWCC using Revo uninstaller (advanced scan and deleting found entries is mandatory after uninstalling)

  • Restarted system

  • Uninstalled Nvidia drivers

  • Restarted system

  • Installed the Chipset INF utility

  • Restarted the system

  • Located the following subkey in regedit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PnP\Pci

  • Generated the HackFlags entry with a value data of 200 as depicted here (https://learn.microsoft.com/en-us/troubleshoot/windows-client/deployment/error-attach-pci-express-expansion-chassis)

  • Reinstalled Nvidia drivers using the latest package

  • Restarted system

  • The card was still being detected as “Microsoft Basic Display Adapter”, so I uninstalled the Nvidia drivers

  • Restarted the system

  • Generated the HackFlags entry with a value data of 400 as previously described (this value worked for me)

  • Reinstalled Nvidia drivers

  • Restarted the system

  • After restarting, the card was outputting video and recognized as NVIDIA GeForce RTX 4070 Ti

  • Reinstalled the latest AWCC

  • Restarted the system

  • After restarting, the card and AGA were also being recognized in the AWCC


Important notes:

  1. The HackFlags entry never worked for me until I uninstalled the NVIDIA drivers each time I modified the subkey; for this reason I suggest testing systematically the 200, 400 and 600 values always uninstalling and reinstalling.

  2. Apparently AWCC can interfere with process since I tried everything depicted below and it did not work until AWCC was uninstalled.

  3. The AGA and card were connected to my laptop the whole time
