I have a Xeon E3-1245v2 and an AMD Radeon HD 7850 installed on my X9SAE board. Why do I only see Radeon listed under Display adapters in the Device Manager?
Please set your Boot Graphics Adapter Priority in BIOS to Onboard so that IGD will get initialized first before the AOC. If the priority is set to Offboard or Slot 6 VGA, the system will skip IGD initialization and thus you will not see it listed in the device manager.
