You should only use identical CrossFireXTM-ready graphics cards that are AMD certified. 2. Make sure that your graphics card driver supports AMD CrossFireXTM technology. Download the drivers from the AMD's website: www.amd.com 3. Make sure that your power supply unit (PSU) can provide at least the minimum power your system requires. It is recommended to use a AMD certified PSU. Please refer to the AMD's website for details. 4.
