One of the questions i often see asked is, "How do i know if CrossfireX is working correctly?" Well i have written a basic and advanced guide that will show you two different ways to check that your CrossFireX setup is working correctly. The first (simple) method will allow you to get a visual notification in the form of an AMD CrossFireX logo every time a game starts and a CrossFireX profile is loaded. A quick and easy way to make sure that CrossFireX is working when you load a game. The second (advanced) method requires you to install a third party application called MSI Afterburner. This will allow to to monitor how your gpu's are performing down to the finest detail. Great for the enthusiast or someone that likes to keep a pulse on what his Radeon cards are doing at all times. I recommend using the latest WHQL driver from the AMD website. CrossFireX users should always use the most recent drivers to keep their CrossFireX profiles up to date. Basic Method - Quick Way To Check If CrossFireX Is Working Open Catalyst Control Center. Click preferences in the top right hand corner and make sure Advanced view is selected. Crossfire should be enabled by default after installing the driver, assuming you've installed the cards correctly and secured the relevant power connections. But lets just double check to make sure that's the case. Open the performance tab on the left. Click AMD CrossFireX. Ensure that Enable CrossfireX is selected. Note only Windows 8/8.1 users will see the option below that. The option to enable/disable crossfire is not present for 7990/295x2 users. Should these users wish to disable CrossFireX for a specific game you need to create a profile within 3d applications, select the game exe, add it, then disable CrossFireX and click apply. Next we need to make sure frame pacing is enabled. Again this should be on by default, but just double check. Go to the gaming, then 3d applications on the left. Click X in the top right hand corner to close CCC to the taskbar. Right Click the CCC icon () in your taskbar. Go to 1.AMD Radeon >> Show CrossFireX Logo. Tick that like in the picture below. Now whenever a 3D Application loads, if CrossFireX is working and has applied a CrossFireX profile then you will see a small CrossFireX logo in the top right hand corner whenever a game or 3D application loads that has a CrossFireX profile.
