    Not working ATI Radeon HD 6770 despite already running on 5450


    Howdy :)

    Here's the deal... i've bought a ATI Radeon HD 6770 from a second hand store. Currently, i'm running on a integrated Intel HD Graphics 2000 and its running fine. I've even bought a Radeon HD 5450, which is working as well.

    But why the 6770 doesn't work? I have the latest driver from ATI and my 5450 work great. So why my little "upgrade" don't work? I didn't tried it on another computer yet... but i'll do it as soon as my other computer got repaired. But right now i try to figure out why one ATI work, but the other one don't...

    Thank in advance :)

    You may have answered your own question,

    bought a ATI Radeon HD 6770 from a second hand store
    Used card from a second hand shop (was it even a computer store?), likely defective.

    We can give you all kinds of ideas but until it is tested in another computer, anything we come up with is purely speculation.

    One thing that isn't speculation. Did you remember to connect a 6 pin PCI-E power connector to the card?

    Well... I plugged it back once in the computer to check something, then I unplugged it but when I plugged my 5450 back, I got an infinite reboot including a BSOD.... I broke a second computer in only two weeks. The first computer... well... "Suicide" himself and the second one died simply by switching GPU... I'm done. I'll never buy a computer again. Sorry for wasting your time.
