The “real” memory of the graphics card

directxgraphics cardnvidia-geforcespecifications

I purchased a desktop two years back asking the vendor to install an Nvidia 9400 GT 1GB graphics card. The NVIDIA website provides the following technical specifications:

Memory Specs -> Standard Memory Config = 512MB

The DirectX diagnostics (dxdiag) give the following details:

       Card name: NVIDIA GeForce 9400 GT
    Manufacturer: NVIDIA
       Chip type: GeForce 9400 GT
        DAC type: Integrated RAMDAC
      Device Key: Enum\PCI\VEN_10DE&DEV_0641&SUBSYS_40091682&REV_A1
  Display Memory: 1775 MB
Dedicated Memory: 1009 MB
   Shared Memory: 765 MB

I'm confused about what the "real" memory is. Is it 1GB? 512MB? Does the words "Integrated RAMDAC" mean the display shares memory with the RAM and the total is 1GB?

download this Tool GPU-Z and run it. It will read all the data of your GPU and show you your memory.
