Help me resurrect a GTX 580 AMP! Solved!  

post #1 of 6
Thread Starter 
Hey guys,

I bought a dead gtx 580 and hopefully i am gonna fix it by replacing the broken IC. However chip is half broken and i can not read anything written on it so, if any of you guys can remove the cooler and tell me what's written on the chip,i'll be extremely grateful. if you do this i'll probably fix the card and it's gonna be awesome smile.gif here is the chip circled in yellow



New content,

i have a little problem left now . after replacing missing IC now i understand why i can not see it in windows or its bios as a second card. beacuse 8 pin 12v rail is somehow connected to a resistor . pcb trace leads to +12v on 8 pin power connector.that resistor is broken too and i have to replace it also but i do not know ohmage of the resistor. i know that resistor ohmage can not be measured on pcb with generic multimeters but some of the twizzer types can read it on pcb too, so i'm still waiting for your help to resurrect this bloody gtx 580 amp ! Resistor is shown with red arrow.

I do not own a 580 Unfortunately, but I did do a bit of searching and found a High Resolution Image of the card, Perhaps you can get what you need from it?
