I have a ATI Graphics Card with 1G of RAM. GPU-Z says that 143MB (dedicated) and 75MB (dynamic) is being used on the card (GPU).

Is it possible to get your PC to use GPU as more RAM (main memory) for normal usage?

Or can you get your PC to be make more use of GPU memory to increase performance?

I would start looking for information regarding "GPU Ram Drives"? For example, create a RAM drive with your GPU memory and then use that drive as a memory extension using ReadyBoost on Windows? I notice Gentoo Linux has some instructions on using GPU as RAM for swap - en.gentoo-wiki.com/wiki/Using_Graphics_Card_Memory_as_Swap Here is a question asking about creating a RAM disk - superuser.com/questions/337707/… - if you can solve this, you can probably achieve the answer to this question. –  David d C e Freitas Sep 20 '11 at 12:26
