I'd not even know what to ask or be embarrassed to ask lol. This isn't a hardware issue IMO so there isn't really anything for me to break / improve or modify. I suppose I'll await support from the Octane team and hopefully we can get this issue resolved.
I sure do appreciate your help Glimpse.

hehe.. You can simply drop a line & ask user managed to find any solution. I'm not really sure what is causing that, but You're not the only who face that. Maybe there is some relatively simple & cheap hardware solution =) like.. for instance using x4 slitter to add multiple cards instead of x1 risers.
It seems this issue is related to using an external GPU via a PCI 1x riser.
I used the test scene you shared with me and your same HW and it seems that the issue is gone if you select for tonemapping in your device settings just those GPUs connected directly to your motherboard.
This is likely an issue caused by a timeout due to the low bandwidth, winch is specially important when using texture baking. However as we currently are in the process of moving tonemapping to CPU so support headless rendering I would not expect any changes regarding this issue as it is likely to be gone once that happens.

it's very likely that is the case. as mentioned earlier some users already noticed this on some x1 solutions. Strangle I've used that on x1 on amfeltecs backplane & couldn't make it crash..so in some cases it works.mojave wrote:It seems this issue is related to using an external GPU via a PCI 1x riser.
