You cannot use normal computer RAM to be dedicated to graphics. The only way you would be able to get RAM that is completely dedicated to graphics would be to buy a video card that has RAM built into it.
Most if not ALL modern video/graphics cards use both RAM from the MoBo and The dedicated RAM on the card.
Integrated, or on-board graphics chips use system RAM instead of dedicated RAM. They are usually very low power, and not suitable for gaming.
no graphics cards have there own built in video ram The above answer is only partially correct. If a computer had onboard graphics, where there is no dedicated graphics card, then the graphics chip is on the motherboard itself. In this case, it will use the system RAM for memory. This can reduce the total amount available to the system. So if you have onboard graphics (no dedicated graphics card), then a dedicated GPU(graphics processing unit) could in fact increase available RAM. However, the difference is not likely to be large. RAM is cheap. Your best option is to buy more RAM for your system.
Video-RAM is the memory built into your video card specifically reserved for video-processing. Modern video cards have anywhere from 128 mb to 1 gb of RAM built in and dedicated to making video games run faster & prettier. This is different than the system RAM your computer uses for running programs, but on many laptops & inexpensive computers a certain amount of system ram may be dedicated to video in lieu of actual video RAM. Technologically video-RAM and system RAM are the same thing, the only difference is in their purpose.

This is done automatically by the hardware. The onboard GPU borrows RAM to use as its own memory.
Depending on the way you wanted this to be answered, GDDR3, and GDDR5 are both common types of graphics RAM. Or if your question was supposed to be asked a different way, most cards have dedicated video ram. This is helpful in gaming situations as most of the latest games require at least 1gig of dedicated vram in order to properly run at the highest settings. Remember not all cards are of the same architecture. If you see a $20 card with 1gig of video ram it's probably not the same as the $400 card with 1gig of video ram.
dedicated memory is memory which is only connected to the GPU. changing shared memory to dedicated memory would involve rewiring the laptop, which would be far more expensive and far more effort than buying dozens of laptops with dedicated memory.
VRAM is an acronym for 'Video RAM' which is the high speed computer memory dedicated to a computer's graphics hardware. Some systems use a portion of the computers normal memory for this, and others have dedicated memory for this.
you can't or you can get more ram but it only increases shared memory video!
No, Updating to the latest driver will not increase the video RAM. This is a chip on the video card or on the motherboard using the pc RAM. The only way to increase the video RAM is by making a change in the bios if it allows you. Some are set and not changeable and if its not already set to the max, or buying a new video card with a larger amount of RAM
