OTOY Forums

this has been bugging me for a while.

i have 2 1080ti cards, running on 3 monitors with 64gb ram.

although i set out of core to 32gb (gpu overhead 1gb)
i keep running out of vram memory. i have no idea what is using up 8gb of my ram (as per log).

how can i optimize my settings to use the cards most efficiently?
i tried deactivating the gpu 0, hoping it will take over the display and system duties, but still i keep getting errors on pretty simple scenes.

Do you have another software is running paralel? Big amount of VRAM is unavailable.

nope nothing.

i did have oculus connected but not active and google chrome.
i deactivated one gpu and now i can render the scene but only with one card i suppose.

any ideas are welcome, thanks

Hi crackfox,
have you disabled the SLI/MultiGPU option in the Nvidia Control panel?

hi beppe,

yes, sli is deactivated in the nvidia settings.

Any updates on the issue? Is it still not working?
We had the same problem with another 1080ti. We tried it on 3 different PCs and it had problems in all 3 of them (2 different X99 motherboards and a Z97). Octane detects the GPU but when you hit render we just get error 7xx. We had to return the card as we can't use it.
I've seen some more people are having similar problems with their 1080 TIs. Would be good to know if it's a Octane bug with the new cards or a hardware issue.

I don't know if you had any progress with this, but I'm having the same problem...so it's not hardware related :/
