The errors are definately not random. When the 980ti is connected it always has the same error. The hardware has been tested ok on other render engines and V4 octane and is not faulty.
Im not an software engineer so my best explaination is it feels as though the memory gradually gets eaten up the longer the render continues until it grinds to a hault.
Im guessing I just require the correct driver for this combination of cards using V2020.2.
If you could kindly tell me the correct driver version for the 980tis using V2020.2 that would be most helpful.
