With the emergence of Crossfire and SLI video card technologies from ATI and Nvidia, configuring multiple graphics processing units (GPUs) is becoming more commonplace. This technology allows multi-GPUs to work together for faster, more powerful processing. Installing multiple graphics cards is a fairly easy-and-quick process that any computer owner can complete in a few minutes.
Instructions
Installing Multiple Graphics Cards
1. Unplug the computer.
2. Take off the computer's side access panel. This may require removing a couple of thumb screws on the rear face of the case.
3. Locate the available Peripheral Component Interconnect Express (PCIe) expansion slots.
4. Slide one graphics card in to each slot. Start from the topmost slot and move down, until every graphics card has been installed.
5. Attach the included SLI or Crossfire data strip to the top of the installed graphics card. The connection point will be marked on the cards, and will look like a smaller version of the card's PCIe interface.
6. Attach the PCIe power connectors from the power supply to each graphics card. Each card will require two connectors. The card will require either two 6-pin connectors, or a 6-pin and an 8-pin connector.
7. Replace the case's side access panel, and plug in computer.
8. Connect the monitor's data cable to the topmost card. The rest do not need a monitor connect as the internal data connector does that.
9. Boot into the operating system, and update the graphics card's drivers if needed.
