Quick guide for extra performance in games

How to set up AMD Crossfire



A few years ago, adding multiple cards in a Crossfire configuration often resulted in significant problems when gaming. For some games, multiple cards worked wonders, while at the same time on another game you saw lower frame rates than you did if you were just using one card. Over the past couple of years, Crossfire driver support and performance has massively improved, and almost every current game will see significant increases through adding a second card. Despite minor issues such as micro-stuttering whilst using multiple cards still exist, the option of Crossfire is still great if you need a extra performance in games.

In this guide, we show you how to set up AMD Crossfire:




First off, you need to uninstall your current AMD drivers. To do this, press the ‘start button’, and then start typing ‘uninstall a program’ and it should be found. Then click on ‘AMD Catalyst Install Manager’, click ‘change’ at the top, and then choose to ‘Express Uninstall ALL AMD Software’. This will remove all the AMD software and drivers, making it easier to start afresh with the latest versions. After this has completed, you may be prompted to restart your computer. When it has restarted, you should also download a driver sweeper program, in order to remove any trace of the AMD software left on your computer.

You should now download the latest AMD driver software here. Choose the ‘express installation’ option, and the rest of the installation should be self explanatory. When that has finished, you’ll be asked to restart your system again. Once it has restarted, your screen resolution should be back to normal again.

Now, fully shut down the system again, as it’s time to install the second graphics card. For now, we’ll leave the Crossfire bridge off in order to double check the second card is recognised in the system. To do this, after installing the card, simply turn the PC back on, and when you get into Windows, you’ll hopefully be prompted with ‘New hardware has been successfully installed’. If this message doesn’t appear, click the ‘start button’, and type in ‘device manager’ and click the option that appears. Then under ‘Display adapters’ you should hopefully see both of your installed AMD cards there.

As you’ve now confirmed your system has recognised the second card has been installed, you can now shut down your system again, and put the Crossfire Bridge on. Once installed, you can turn your computer back on, and when in Windows, open up the ‘AMD Catalyst Control Centre’ from the tray icon, and  under the ‘Gaming’ tab on the left hand side, choose ‘AMD CrossfireX’ and choose ‘Enable AMD CrossfireX’. Restart the system again, and your system should now be set up for AMD Crossfire!

You can do yeah (with AMD at least), but the 4GB card will be reduced to 2GB.Quote

I had 2 7850s in Crossfire for over a year and out of the box it was pretty bad because of the microstutter. RadeonPro ( solved the microstutter problem in almost everygame except for a few. Far cry 3 was unplayable even with RadeonPro profile for example, but others really became smooth. Just thought i would share this for anyone thinking about getting another card Quote
