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?

    It looks like it is a 1GB card. How much memory does your system have?

  • Integrated RAMDAC= Random Access Memory Digital-to-Analog Converter. It's a piece of hardware which produces analog signal which drives analog monitors. Integrated in this case should not be a problem. Integrated RAMDACs have been the norm for quite a while.

  • Thanks AndrejaKo. Ramhound, my system has a 2GB RAM, excluding the Graphics Card - which I was hoping will be 1GB additional when used. Feb 6, 2012 at 15:04

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

  • Confirmed that memory size is 1024MB. Not sure why the NVIDIA website says otherwise. Feb 6, 2012 at 15:08

The way I see it : Dedicated Memory: 1009 MB - this is the onboard memory on the video card itself Shared Memory: 765 MB - This is system memory (plugged into motherboard) the card can use along with its own dedicated onboard ram.

Another neat application to check this information, and additional information about your PC, is Speccy https://www.ccleaner.com/speccy.

Pretty neat information, not invasive/instrusive and no adware software either (Just make sure you're getting it from an official site).

Hope this helps.
