Many of the people have asked almost the same question. I'm trying to render a big mesh + fur/grass file with a few characters on the screen.
when I hit render, after a number of processing, copying data to gpu etc... i get following error.
Mem: 2960.07M, Peak:2960.07M | CUDA error: Out of memory in cuMemAlloc(&device_pointer, size).
I'm using Geforce GTX 690 which contains 4GB memory.
Can somebody tell me how can i get GPU rendering, while 2960M is far less then 4196M of memory.
I know somebody would suggest me to use CPU.. but i'm curios why not GPU?
I've already compressed texture, etc
I don't think any other application is using any of my 1GB remaining memory. everything is closed but blender is there, also the GPU utilities are showing 2000/2000 MB are free on one card and 1900/2000MB is free on 2nd card.
i'm using GTX 690. with two GPUs of 2GB each. If somebody thinks that one GPU should have memory matching to the cuda memory/or Peak memory then I'm doubtful. Because in preferences Blender does know that I have 2GPUs where I can select either first GPU or second GPU or even both.
When I render some of smaller objects/scenes both of my GPU renders simultaneously with two blocks.
I'm running following specs
Xeon E5-1660 0 24GB - 1600mhz GTX690
