Need pictures of GTX 770 twin frozr

[BennyKG]

Well, long story short, I got scammed and bought a faulty GTX 770. There are 7 missing capacitors C4037, C647, C643, C648, C654, C663, C821. I was wondering... I I could try to solder on some capacitors with the same capacitance as some which look identical to the ones missing in the hopes of making it work. But I need pictures so I know which ones look like which.

in the centre you'll see 4 of em and right at the top is another.

to the left of the screw, right at the top.

diagonally from the +

Where did you buy the gtx 770 from maybe you can file a report something like that because i dont think it be safe to add capacitors onto the gpu now because it still may not work!

well I got it off OLX, it's like the Romanian version of Gumtree. Worth a shot trying to repair it. There's nobody around here who knows how to do anything to repair boards.

Also, it works fine without drivers, but the moment I install them, it drops signal when booting into windows. I've tried everything related to software. Time to move to hardware.

I would only rely on pictures of something with a very closely matching serial number. They do go through manufacturing revisions during a cards lifetime.

But that stuff is easily found on google images. Almost every high end card is dismantled and high resolution images shown of the PCB.

I have tried looking for them and none of the pictures are high enough resolution to make out the colours of the capacitor. You see, there;s also some yellow ones alongside the dark & light brown ones, which come in similar sizes. I'll keep looking though.

Never mind... I found some on some kind of russian website. Now, the picture I found is for a 1v282-3.0 and mine is 1v282-3.1. That shouldn't make a difference, right?

You can't go by capacitor colours to tell you what nf and voltage they are. The only way you can find out is by getting a circuit diagram of the correct issue and version of the PCB. By their placement on the PCB they are probably 10nf or 100nf decoupling caps ( usually rated at 50v ), but don't take that as gospel.

oh ok. thanks for the advice. I'll try look for another method of fixing it some other time.
