  1. Have you tried using it in another motherboard ?
    Also try updating your BIOS too
  2. card works fine in another board . asus just brought out bios 2002 for striker extreme will give that a try.
  3. updated bios to latest version which is v.2002 still no joy.

    That's strange,have you tried using it on different PCI-E slots ?
    And what's your PSU ?
  5. tried all 3 pce ex slots . p.s.u. is corsair vx 550.
  6. I did a search and found this
    "PCIx version 2.0 cards are backward compatible with version 1.0, so this should definitely not be an issue. In some cases the video card's installed BIOS may be incompatible with certain motherboards. In this case you can get a BIOS revision for the video card from the card manufaturer that will fix this and you will need to install the video card on a machine that is supported long enough to flash the video card BIOS. Call the manufacturer and ask them specifically about the video card BIOS being incompatible with your motherboard. If they say there is no known issue then make sure that your PSU supports the video card, and if so then you're home free."
    So try updating the VGA's BIOS and check if it helps(it's risky though,but its the last thing i can think of).
  7. Been searching for bios file cant seem to find one. registered with xfx tech support to see about compatibility. lots of bios horror stories on web. worth a try though if i can get bios from a worthy source. thank you...
  8. Let us know how it goes.
  9. Spoke to xfx tech support they said there is no known issue of compatibility.
  10. Got it working in middle pci-e slot . pc runs fine but cant install gpu drivers
  11. This is the error i now get in device manager. Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52) .... tried older drivers tried just the drivers without ccc .. i have a x-fi soundcard i've tried uningstalling software and removing card still no joy... sorry its been so long thanks in advance
  12. fresh install of windows works like a charm now drivers installed fine . only works in middle pci-e slot .
    got there in the end thanks for you're help.
