OTOY Forums

Hi all,

Not sure if this is best posted in the C4D forum or an area dedicated to Octane standalone (not sure if this is a C4D plugin issue or a more general Octane issue).

I recently installed another GPU in my slave machine and with heavy scenes the daemon has been crashing.

I'm getting a long string of error messages saying... CUDA error 2 on device x: out of memory

It seems to happen on three of the four devices (GPUs), hence the 'x' above, and there are various sub errors, e.g. out of memory, failure to allocate memory etc.

I have 10gb of RAM allocated to out of core textures and previously I've not had a problem with heavy scenes which exceed my VRAM limits crashing my slave.

Also I've noticed sometimes I can render fine in the LV but when I use the picture viewer in C4D it crashes, on exactly the same scene.

So far I've tried rolling back my Nvidia drivers to the previous version (398.11) but that hasn't worked.

The last working setup was with three GPUs in the slave machine (2x 1080's and 1x 1080ti), and Nvidia driver 398.11, and Octane 3.08.02

I started getting errors when I added another 1080ti to the slave machines (so 2x1080's and 2x1080ti's) and updated to the latest Nvidia drivers.

As said above, rolling back the drivers hasn't helped.

Could the extra GPU be the issue? (Can't see how).

My specs of the slave machine are...

Win 10 (fully updated).
Octane 3.08.02
C4D R17 (running on main machine)
Asus z270 ws
Intel i7-7700k
32gb ram
2X GTX1080
2X GTX1080ti

Thanks in advance for any help, and please feel free to move this post to a more suitable forum area if this isn't a C4D plugin issue.

Cheers

Hi,
take a look at this other discussion in the General Discussion section:

ciao Beppe

Thanks Bepe, not sure that issue is the same as mine.

I'm not getting a BSOD crash, just error messages in the slave daemon which stops the slave from rendering.

Also I have a z270 WS board not an X99, my board has a PLX chip but not sure it's the same one.
