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?
