I am having some issues with my new SAPPHIRE 100356OCL Radeon HD 7790 OC 1GB DDR5 PCI-Express Video Card.
This card is an upgrade from my 5750 that had been running smoothly.
From time to time I will recieve the message "Display driver amdkmdap stopped responding and has successfully recovered." I receive this message while doing non gaming activities.
While playing world of warcraft(in windowed mode) and bioshock infinite(fullscreen) I have never once received this message.
I have done a bit of browsing on the web for a fix but all attempts have not solved my issue.
I was first using the drivers available on the AMD website but as this issue started to occur I switched to the drivers that came on the CD with the card. I have performed a full driver uninstall with drivesweeper in safe mode. My install of windows 8 is fairly fresh but was in place before the card was installed.
I added a TDRDelay of 8 to hklm\system\currentcontrolset\control\graphicsdrivers
This seems to have made the issue occur less frequently as it will wait a little longer before timeout but it has not resolved the issue fully.
Any help would be appreciated.
