Rendering a small test animation with directlighting kernel always fails with the errors below. The scene only uses 329 MB of VRAM. After the error occurs, C4D needs to be restarted, otherwise no further octane renders can be made. infochannel kernel works. Didn't try PMC. I tried adding the TrdDelay registry key as per some post on here, which didn't help either.
I'm running a system with 5 x 780Ti cards. Tried disabling some/a few of the cards, no change.
Any hints anyone?
Here's the log:

Hi Why does my slave render for 60-100 frames and then I also get CUDA 700 illegal memory access. What does it mean illegal memory access? RAM was sent to wrong part, no enought vram?> Thanks
