Can I create a RAM disk using GPU Memory? [duplicate]

Is it possible to use GPU memory as more main memory?

I would like to create a RAM disk/drive using the GPU's RAM/memory.

Then use ReadyBoost on Windows to use the disk as extended memory.
Any tips?


Apparently this is possible with Linux:

Graphics cards contain a lot of very fast RAM, typically between 64 and 512 MB. With Linux, it's possible to use it as swap space, or even as RAM disk.

But I've found nothing similar for Windows.
