A free XFX 7600GT 256m

This is a copy of a thread I've made on another forum. I think it's all OC3D savy, if not a mod can edit it accordingly.

---------------

At many technical places where people work, these days electrical waste gets separated so u end up with a mini bin with all kinds of scratched monitors, keyboards missing posts, pc components, cables - u get the idea.

(whilst we're on this subject, even if u don't work at a place that has these, be aware that many companies with technical departments have such bins - how u go about looking into those... I don't really want to know or advocate)

Anyway, I always look into these. U will find people dump whole pcs. Well there are sinks, chips - sometimes memory, cards, drives - who knows. All destined for the electrical shredder cos no1 knows their value to the weird amongst us. Servers that have failed, loads of secondary gear to be salvaged.

I've gotten loads of little things. Recently tho I saw a load of pci cards in anti-static bags. Rifled through the top 3 or so in the pile and they were editing cards that I already knew were a pita to install on anything. The company was no-more and they were indeed sh1t.

.. what's this ? A pcie graphics card with an XFX logo. Whilst still moist in the groinal region, I looked at the card and apart from some strange wiring on the back, it was obvious 2 caps had totally exploded. Goo oozing all over them.

.. caps are replaceable.

I neglected to take a pic of the card in it's broken state, probably as I was a little excited. Thing being, although it's not the best card in the world, I had a use for it in one of my pcs that would free-up a card that was too good for it.

Fortunately I know of some1 handy who is very good with a soldering iron. Part of his job and he's done it for decades.

B4 I'd come back from getting my coffee, he'd taken out the caps and replaced them with some as-good ones.

Ideally, the method would be to source the exact component that u can see is obviously faulty. But in this case the caps were as-good, even tho they were of a different type.

At this stage tho, u have replaced the faulty part, that doesn't always mean that the device is fixed. It could have been that something else had caused the caps to blow. So ofc u need to test the device. I chose to use an in-house pc (hey if it breaks/blows the pc, the company can eat it - or in our case the leasing company would eat it as part of their contract). Spookily it started up straight away and not just being happy with this I made sure it passed many runs of 3d benching tools to be sure. To output a basic vga signal doesn't require much work from the card. Something as simple as linux/dos running can be done without sweating.

So some pics:


Here u can see the 2 odd looking caps. Who cares what they look like ? Notably, they were like the cap to the right of them (cept with plenty of goo frothing from the top),


Excusing the poor focusing technique, I've obviously circled the pairs of legs for the new caps. Things like caps almost always get soldered with their legs sticking out the bottom. This is meant to make for an easy off-and-on process for replacement soldering of components. However in this case I was told there was something on the surface of the pcb that made soldering pretty difficult. My theory here is XFX coat the pcb with something that hinders ur approach.


A point of interest, nothing to do with anything I'd organized. But the card had already undertaken a mod of sorts. What we see here are 2x timing crystals that seem to have replaced 2x that were missing from the pcb surface. Whether this was done by XFX prior or some1 in-house, I couldn't say. I would highly doubt any1 I know has done this. (for 1, with the greatest of respect, it's too professional and the running green lines are... hard to say.. "tidy?" maybe) U can see the reference points they've taken. It could also have been Mac related - I really don't know.


Here's the finished product. As far as I'm aware to this point, a fully working XFX 7600GT 256m. Not the greatest card in the world. But it was 1stly free and 2ndly going to take the place of a card that's being wasted in it's current use (8800GT 512m).

Keep a keen eye on what technical stuff people throw out !

Nice work, I like seeing things like this.

Where do you work? I'd love to work somewhere that threw out 7600gts, let me fix them on a coffee break and then test them in a work pc

A certain broadcasting corporation.

Finds of this type are very rare. But u do find people dispose of a pc every now and again - u know it's gonna be an old one, but little things in them are very useful. Often by the time I get there, the vultures have already circled cos the cases are generally open. Even so, IT people see one thing, computer people see something else. Not something u can learn in college

I was at Sheffield Uni doing computer science and was handing in a key to some lockers they have in the labs. In the "office" theres all the usual half repaired PC's lying around but next to the front desk was a box that was piled high with old graphics cards, sound cards, heatsinks (some which looked pretty good!)... all sorts!! Soooo wanted to have a rummage through it but just ignored it in the end, but bet there were some good finds like this in there! Congrats on finding it and actually getting it working too!!

heh, I have a Terratec with the exact same added PCB it seems, mines also came from a bin from a broadcasting place Someones throwing them out and asked if our flat could use one...

Nice repairs, my 7900GS needs something similar but I am ham fisted and would only make things worse

lol not a bad find!

I sometimes see PCs people have left outside for the dustman to take...

Have never bothered to take one as I reckoned that it would be more hassle than its worth. But after reading this I might take the next one!
