Video card temperatures typically range from 40C to 80C. Most high end video cards such as the Radeon 6000, 7000 and R Series typically display temperatures 50-70C idle and up to 80C-90C at load. The latest 7000 series cards run hotter than most and can reach a maximum of 105C. The heat sink and fan assemblies attached to the video cards are specifically designed to reduce temperatures as much as possible. If you are having trouble with heat we recommend turning your fan speed up to 100% your AMD Catalyst software under the Overdrive section where you can tune your graphics card or you can adjust your voltage and clock speeds to find the optimal performance to heat ratio.
Generally your graphics card should auto detect the device that is connected to the monitor however in some cases it might still be defaulted to your integrated graphics card which is the motherboards video output.
If you were previously using an integrated video device on the computer, connect the monitor cable back to the port that you used to connect to on your motherboard. Boot up into the motherboard's BIOS settings, consulting your motherboard's documentation if necessary, to disable the integrated video card, save the settings, and then reboot with the monitor cable connected to your new video card.
If that doesn't work, try swapping out your system RAM and running each stick one slot at a time and one stick at a time.
Also, make sure that the power supply meets the minimum requirements of the video card. More important than the wattage will be how many Amps are available on the 12v power rail of the power supply. You can check this on the power supply unit itself by removing the side of the case. The label on the power supply will list the 3v, 5v, and 12v power rails. Add up the number of Amps listed next to any 12v rails listed and make sure that the total is greater than or equal to the minimum required listed on the side of your product box.
If you are using two or more graphics cards, only one of the graphics cards may be assigned as the primary graphics card which the system will default to. If this is the case, you will need to try different ports on either card to see if it is detected. Generally, the PCI slot closest to the CPU is the primary, however previous settings may have changed that so check your settings both in your BIOS and driver utility software to see what your current configuration is.
It is generally recommended that you remove existing NVIDIA software and drivers because they share some applications that may have conflicts such as the Direct X drivers.Follow these steps if your upgrading from a previous Nvidia based on graphics card:
We strongly recommend that you uninstall the previous video card drivers before installation of any new ones. This is done through the "Add/Remove Programs" menu in the control panel, also known as "Programs and Features" in Vista/Win7. You will need to remove the Nvidia display drivers and physx.
You may want to also wipe out any and all software associated with your NVIDIA graphics card(s). To do this follow the instructions, step by step, below:
- Click on the Start Menu
- Click on Add/Remove Applications
- Scroll Down and you should see a set of NVIDIA applications
- One at a time, click on the application and then choose remove from the button at the top of the window. Wait for each process to complete before beginning the removal of the next application.
