cycles hair... CUDA out of memory[solved]

Hi,

I need dense and detailed hair on a charakter. I did a setup of 300000 hair and interpolated children. Now my CUDA memory is to small to render that. My graphics card is an Nvidia GForce 660 GTX Ti.
(CUDA error: Out of memory in cuMemAlloc(&device_pointer.size))
Is there a way arround or a solution for maybe using hard disk memory or ram to calculate the rendering? Or any other ideas how to render dens hair without using the CPU render setting?

Thanks a lot!

No

Or any other ideas how to render dens hair without using the CPU render setting?
Buy a card with more memory. Buy time on a render farm. Render multiple times with less hairs then composite them into one.

o.k. thanks a lot!
