Also, the operating system will take up a chunk of memory on the gpu attached to the monitor. This memory will not be available for rendering. This is why you see total at 4gb but only 3.5 available for rendering. If you disable the gpu attached to the monitor the amount available will go up. Octane also needs a smallish chunk for its code so available plus used will always be less than total.
I hope that makes sense.
I think I understand in terms of what is shown as "Available". Not sure I understand in terms of "Used" for the actual render, or if I can increase the "Used" in my render set up to actually speed things up.
If I disable the smaller GPU , as you suggest, would I be doing so via the attached graphic (Nvidia Dialog Box) , or is there some other recommendation, like plugging both monitors into the motherboard (not even sure if this is possible)? Or, are you saying that if I uncheck the "Active" selection for the GTX970 via the Octane Render for Carrara Settings/Devices dialog box, my performance (Used + Available) will go up even though I am utilizing fewer GPUs?
Just curious, does "Used" refer to the limit of what is actually being by Octane during the Octane render, or what is used by the system overall?
Thanks for your help,
