X670E Taichi iGPU driver crash

1. Display driver amdwddmg stopped responding and has successfully recovered.
2. Display glitches(If lucky) No record at event viewer.
3. Screen artifacts (No recovery except a restart after which it starts again. No record at event viewer.)

Either display driver stopping, display glitches or screen artifacts. So often that PC is not usable.

I have the same CPU and motherboard with no external graphics card. Installed it with an old Samsung 960 EVO and 1 more SSD and 1 HDD with Win 10. They weren't used for about 3 years. BIOs updated to latest before turning PC on. Windows 10 updated to latest, graphics drivers updated, DDU and updated, did a lot of trial and error on Windows, tried usb-c instead of hdmi with a different cable that I know works well, disabled EXPO profiles, reseated CPU and memory sticks, did memtest on the sticks, CMOS clear, disable freesync, decrease refresh rate, disable HDR, etc. Maybe old drivers of old hardware cause issues? Ok, did a clean installation of windows 10, still no luck. I'd keep getting different errors. If I was lucky, it would be 'Display driver amdwddmg stopped responding and has successfully recovered.' at Windows event viewer. If I realized this is happening and stopped moving the mouse or typing anything on the keyboard while it is ongoing, it would be back to normal after a few seconds. If not, screen artifacts would form all of a sudden and I would have to restart and nothing except a restart would fix them, and that only for a short time before they reappeared. Sometimes screen artifacts would start just on Windows explorer, not even when watching any video. The frequency of this happening increased so much over time that I would not be able to use the computer more than a minute. I would switch back to some previous BIOs version, but I wasn't sure which one, even though 1.07 seemed the best option since 1.09 release notes mentioned they 'fixed' some iGPU issues. Switched back to 1.07 directly thanks to your post and now all errors are gone.

ASROCK, it is not acceptable that such a critical bug has not been found or not been fixed for the past three months. A Mobo costing over 499 and I have to troubleshoot the hell out of every component? First time ASRock here because I wanted to give a chance to some competitor of my usual ASUS, but I am having second thoughts now. When will this be fixed on the latest BIOS?

Screen artifacts and monitor randomly not getting any input signals from the graphics port was back a few minutes after Windows started. I had to revert to 1.07 again so that system would be stable. Does anybody have an ETA for a fix? Was this error even acknowledged?

Tried 1.18 as well. No help.

Contacted support. I was recommended to exchange both CPU and MOBO. Trying to find a solution with AMD. I don't know what the actual error is because even with 1.07, the display driver stops responding once every few hours. This is much less often than with other versions and is not as annoying, and there are no artifacts with 1.07. but still, there is a problem and further problems can arise later.

I will report here whenever I find a fix, with replacement of either MOBO or CPU or both.

Thanks for the update, glad to hear you have your system up and running
Enjoy the build
