GPU PCB experts needed. HD 6950

[KamiKatze]

Here's the deal. I want to buy a defective Sapphire HD 6950 for litecoin mining off of ebay.

 

The way that it is defective, is, that a micro chip fell off the PCB. The seller claims that since then it only produces stripes. Now i need to know if this micro chip is any important for just running it on load 24/7. i don't care about image output when I'm mining on it. I attached some pictures, it's just a tiny chip. The number that stands right next to it is 1720. I'll also leave a link to a full picture of a Spphire hd 6950 PCB.

That's actually a very interesting question, I will be listening in here.

I hate that if nobody answers within 3 minutes the thread get's lost forever. With that said, off to the new content!

That looks like a voltage regulator. Definitely necessary for operation.

I apprehended sth. like that. How sure are you?

Not certain. But I've worked with surface mounted components a lot and it certainly looks like one. I wouldn't recommend getting it anyways unless you're confident about the part number and how to replace a SMT component. I can't see it very well, but it doesn't look like the connecting pads are there.

I guess I'd have to get the exact same chip that fell off and learn how to solder in such a small scale.

 

It was just one of the better defective AMD cards that i found on ebay for mining. Most other cards just straight out turned black out of nowhere. But this one is absolutley fine, except for that tiny chip. but if it's a voltage regulator it's pretty much dead.

cant you buy a replacement from ebay

Meh. i don't know. And as i know my luck I' screw up the soldering. Anyways, it sold for 44€, I'd never have spent that much.

The chip is either a voltage regulator or a stand alone transistor.  If you can get the part number and buy it from digikey then I would do it.  It's a simple fix as long as it didn't fry anything when it broke.
