Crashing with Denoise

I am rendering in 3ds max 2019 + Octane Render VR 4.02.1_-_6.14
Computer have a 64 Gb RAM and 7x GPU GTX 1080ti

When rendering, scene use a 24Gb RAM and 4GB VRAM. Resolution of rendering frame - 3840x3840px

Problem: When i enable a denoise, and use all 7 GPUs for render (not mater how many gpus used for denoise) - 3ds max is crashing. I can use maximum 6 GPUs with denoise. Without denoise i can rendering with all 7 GPUs.
I am try rendering on computer with 32Gb RAM. Without denoise i can use all GPUs, but with denoise only 3 GPUs.

I think denoise depends on the amount of memory, but windows shows a many free memory

Hi vshevnin,
denoise depends on VRAM avaible and render size.
Try deactivating the GPU connected to monitor and use that to denoise.
It could depend on your PSU.
