I purchased a desktop two years back asking the vendor to install a "1 GB" graphics card. The card which is installed in my system is Nvidia 9400 GT, and 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 am pretty confused now as to 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?
Can someone explain this please?
