its 500 1 poly planes with image textures on each one. Any clue why this is happening? Im absolutely not hitting my vram limit.

Octane 3.0beta 2, latest nvidia driver Windows 10. 980 Ti hybrids.

Man what do you read here, over the red line?

I see it in the log, but its not making sense with whats printing out in GPUz as far as actual usage. Ill try to resize all the images and see if it helps. I was under the impression that 3.0's alpha and beta were still misreporting stats.

Gpu-z and octane's stats can be different. Or Octane cannot be using all memory. But that's very clear on output log. You can ask to Octane developers for more. That's what we read from plugins.
Also can you please keep to post in Alpha/Beta topics especially this kind of special issues. That's my special request note on every release topics. It help me to track the development processes.

Last note: You can try to use or increase out-of-core memory in case.

Will do, out of core was super slow, so I just batched resized all the images down to 20% of their original size. Fixed the issue immediately.
