GeForce 8400 is a high-performance video card used for video games and multi-media applications. It features 512MB of video memory, full DirectX 10 support, SLI technology and dual DVI outputs. The GeForce 8400 is also compatible with Windows, Macintosh and Linux operating systems. However, when installing the GeForce 8400, like any video card, problems can occur with compatibility and other factors.
Motherboard Incompatibility
Video cards come with a few different slot types. This includes PCI, AGP and PCI-Express. The GeForce 8400 uses PCI-Express technology specifically. If your motherboard is outdated, or does not contain a PCI-Express slot, the GeForce 8400 will not work. So before purchasing a video card it is important to refer to your motherboard specifications to check for compatibility.
