    I got my hands on a Radeon 9800, which has a missing chip. I have no idea how the guy managed to break it off:

    U90 and U89 are the same chips.

    Is it possible to repair it, or could it even work without it? Or should I toss it into garbage?

    Regards, Partizan

    ^^ in english please? lol

    umm....does the card work still? if so, then the card will probably have a limited life span.

    i had a 9700pro a while ago that had a similar problem. except that it was two chips that were falling off. they were still attached, but not making any more contact. the card still worked for a while, but it wouldn't OC anymore, and after a few months, it ended up dying entirely.

    as to repairing it, if the chip itself still looks in good condition, you can sauter it back on is the only way i can think of fixing it.

    Hvanen't tried the card yet, because I need to get a cooler :)

    But I found a guy who can repair the card, but I think I will have to get a new chip, cause the old one is missing one leg (don't know how they are called). Will know more on tuesday and report back.

    The "chip" looks like a voltage regulator. Given it's location on the board, it is probably the voltage regulator for the ram. That is bad news as the card won't run in that case.

    I work with those type of components everyday where I work, but unfortunately I really don't have any way to determine what exactly you have there. Without knowing the manufacurer of the part, I have no way to look up the number printed on top. I will try to get a look at some we have at work and see if I can come up with anything.

    Be sure none of the now empty pads are shorting. Putting the card in should not hurt anything, but I really don't think it will work.

    Thanks for the tips Retarp. As it looks two solder points are broken off (best seen in the first picture). I don't know if it can be fixed. Will have to wait for that pro guy what he is gonna say. It would be nice though if I could fix the card as I got it for free. And I would put it into my second computer instead of the radeon 9250 :D

    If you solder a piece of copper on in place of the missing legs you could get away with that... I think... I've done that trick with old Tandy's :)
