I am using NVIDIA 9400GT but..

I am using NVIDIA 9400GT 512 MB PCI Express. but on the cards box I have seen a sticker in the place where it's written 512 MB, after removing it I saw it's written 512 shared memory....what is this...???

It means that the card uses the system memory as extension to the onboard memory if it needs it... that card probably had only 256 or 128 megabytes of physical memory and the rest is system memory it can use if need be.

Let me provide an analogy, if you don't understand already.

Russia is fighting the United States. Russia runs out of troops. Without shared memory, Russia is as good as gone. With shared memory, Russia can draw extra troops from another battle they are fighting versus the British if it needs to. The fight versus Britain would be cpu load and the fight versus the United States would be video card load.

Typically the cpu in a computer will be doing less work than the gpu during gaming. It is also typical that one has more system memory than gpu memory.

Now, Russia didn't get better weapons, (gpu) they just got more troops (memory). The only downside to this is that the fight versus Britain has less troops.

Hope this helped. It was fun typing.

But it has nothing to do with the CPU, it only has to do with system ram. When the card runs out of GDDR memory it starts to use system memory like integrated graphics does.

That's what I meant to say.
