I am using an AMD 6900XT and am experiencing either complete crashes, or weird artefacts on projects that take longer than an hour to complete.
The program crashes with the message to reduce VRAM usage or limit or machine load (VRAM is reported to never exceed 3.5GB from 16GB available, system memory never exceeded 7GB of 16GB available, no other programs running, max GPU load 60%, max CPU load 40%).
Even though GPU usage and temperature is very low compared to other applications, I am experiencing extensive stability issues.
If the program does render a project, a couple of hours into the render some weird artefacts appear (black square covering approximately 1/3 of the screen, see image below). This can progressively get worse, covering 50% of the screen later and eventually blacking out the whole image.
I have tested this with Artemis Medium, High as well as with Proteus.
CPU is 3900x, motherboard b550. Windows 10 latest, AMD drivers 21.11.3 stable.
Have tried reducing GPU clock and memory clock, disabled ultra low voltage. No changes to stability or the artefacts appearing.
Are any of these known issues? Thank you kindly in advance!
