Updated all drivers and firmware of the graphics card. Complete uninstall and reinstall of all Nvidia programs (Game ready drivers and studio drivers). Complete uninstall and reinstall of all blender versions listed. Once the error appears, change the mode from OPTIX to CUDA.

If it succeeds, redo the render 2-3 times and see if it shows up (usually occurs on the second or third render)

In the rendering options, Enable Optix denoising in the rendered view, and make sure that OPTIX rendering is enabled and selected in settings.Tried rendering with ReBar enabled and disabled.Īll combinations attempted failed to fix the issue.Įxact steps for others to reproduce the error.Tried to enable and disable Optix in settings.Confirmed that no overclocks were applied to the graphics card.Updated all drivers and firmware of the graphics card.


However, Eevee rendering works just fine both before and after the glitch occurs. After that, all attempts to render in cycles fail with the same error mentioned above. Initial render attempts will run properly, but subsequent rendering attempts will fail imminently with the error (Failed to create CUDA context (Illegal address)) after enabling Optix denoising.
