    5450 isn't 2.0 card. it is 2.1 card. more like you should buy a GTX 460 or 260 if you dont have $200 budget.

  2. pcie-2.0 cards will run on you mobo http://www.intel.com/support/motherboards/desktop/d915gav/sb/cs-012066.htm. pcie-2.0 is backwards compatible
  3. Thanks for the info just bought the card today, what is backwards compatible?
  4. forgot this link which explains the different versions:

    http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_2.0
  5. it means that the newer 2.0 technology (the card) will work on the older technolody (the mobo).
  6. If you are having a problem with the card, I recommend you check that you have the latest mobo BIOS as some older mobo's do have problems with 2.1 cards and fixed this with a BIOS update.
  7. Thanks for all your help, will try the bios update, if it still won't boot up should i look at my bios settings?
  8. what is your psu? check how many watts it has and let us know.
  9. My power supply is 500 watts
  10. If it still doesn't work go into bios and make sure you don't have to turn off the integrated video adapter and/or change the pci-e slot to dedicated video.

    Regardless, get the latest BIOS update for that motherboard.
  11. And if all else fails, you most likely have a motherboard that stopped support before all the fixes came out for compatibility issues, which means you are looking at getting a new mobo. But I would check with intel first if your particular mobo has a fix for pci-e compatibility.

    Your power supply is powerful enough by the way, just wanted to make sure.
