What happens when you have 4GB of video memory on your 32 bit computer?

System memory and graphics memory, become two different things when a dedicated graphics card is used.

When you have Integrated graphics, it's on your motherboard in the form of a chip. (Also called On-board graphics. Stands to reason, because it's SOLDERED to your motherboard) ('Chip' is a slang term for IC. Integrated Circuit)

Integrated graphics, shares some of the systems ram memory, and processor resources.

A dedicated graphics card has it's own processor, (GPU. Graphics Processing Unit) ,and ram memory, (Graphics memory)

This frees up the systems resources and allows the system to run the Operating System, and Programs or Applications.

So you can have 2GB's of System Ram, and 4GB's of graphics ram.

Or 1GB of System Ram and 4GB's of graphics ram.

Or 4GB's (3.2 to 3.5GB's as we all know) of System Ram, and 4GB's

of graphics ram.

Do I need to go on?

I think you mean RAM Not Video Memory.

A 32 bit Operating System actually does NOT cap at 4GB. It caps around 3.5GB or around there.

Which means it can only use 3.5GB of RAM at ONCE.

Having more then that in a 32 bit OS environment only helps if the memory is maxed, and the system is looking for the fastest empty address available to use by the system.

32bit systems Can use more than 4GB using a official Windows tweak

called PAE (Physical Addressing Extension)

And the computer will auto allocate video RAM

System RAM takes priority over Video RAM so it will not overallocate

Those new video card that create over 4GB of video RAM is for spanking new Desktop that have 8GB RAM

4X2GB DDR2 Sticks = 8GB

32 bit computer does not recognize 4 GB of ram

those video cards have their memory comes built on them.

the 2 gigs are dedicated to the video card it's self and not the computer which is now free to use ram the other wise would have been used by the card.....read the whole question guys!!
