NVLink / total VRAM

[khomatech]

Hi,

I have 2x 2080Ti connected via NVLink, SLI is enabled. Both monitors are on card 1, card 2 is free. I've set up both cards to be each other's peers, hoping to get 22GB of total VRAM. Unfortunately, it's still showing 11GB total.

What am I missing?

Thanks in advance.

Hi,
you need to consider NvLink like Out-of-core, but instead of moving part of geometry into system RAM, it uses the other GPU VRAM to store the data.
So it is always 11GB + extra NvLink peer memory.
