Soo I got a deal on an r9 270x 2gb graphics card for 40 bucks... a good price for a relatively modern card. We met at his place, he showed me that the card was in fact working and I went for it. Came home, installed it into my budget gaming pc and it was all good... for 3 hours... after about 3 hours of moderate usage, the screen froze. I restarted the computer and the screen was all messed up (artifacts, etc). Turned it off let it sit for a while and came back an hour later. After an hour, same thing. It wouldnt even boot into windows, no matter what I tried. So I took the card out. Upon closer inspection there were 2 things that bothered me. 1: it looks good. What I mean by that is just how clean it looks. I know that people clean gpus before sale but this doesnt look like a used gpu. It looks too clean. 2: you know that epoxy that they put around the gpu at factory? Well one piece is missing. That probably means that it had been repaired before. There is no flux residue though. Tried contacting the seller but his number has been deactivated. What should I do now?

Re: I might have gotten scammed
look up the data sheet first or whatever says how it works . and go from there .. things work sometimes but will they sustain working within design limitations ? average joe wont know such things so its up to you to decide before purchase.. probably bad capacitors again ..Comment

Re: I might have gotten scammed
And that fluffy blanket u put the GPU on doesn't really help...
I have reflowed so many of those cards....

got it w/o the gpu for 120...
I've heard of "reflowing" but does it last, after it had obviously been reflowed before? I dont want it to fail after a month... I want a reliable little machine not a ticking time bomb
tried calling the seller, his number is still downLast edited by nick122; 09-05-2018, 11:05 AM.Comment

by patatapaTrying to repair a Sapphire R9 270x that has a million issues, and recently i added another one. I broke one of the legs of what looks like a transistor at Q252 on the board near to the fan plug, with the marking C3k0P. I have searched everywhere about it and can't find any info as to what it might be. I initially suspected it was a diode but seeing that the board marks diodes with a D i dismissed that idea. It is marked with a Q which means it is either a transistor and for some reason it has a different name than the rest of transistors on the board, a mosfet or some kind of voltage regulator....

Built the computer and used it for a bit till I upgraded and sold the old one to my cousin years ago. He has since built one himself and quit using the one I sold him and I bought it back for super cheap. It has 2 XFX R9 270Xs in crossfire and as I was cleaning the computer (complete disassembly of case and new thermal paste on everything) I knocked what I think is a capacitor off the back while trying to be as gentle as I could with my bare fingers in between things. It is numbered "C2241" on the board and I would like to know:
1. is the cap even needed? (watched a few... -
by tony359Hi all,
I have purchased a "spares or repair" AMD R9 270x on the bay, just as a fun project.
The board worked in my test system. I ran some tests and all was well. When I tried it in my main desktop, it refused to display a picture.
Back on the bench and it was booting up 50% of the time.
I found a short on a line - on the right hand side of the board, not the main phases on the left. Injecting 1.5V I identified a shorted capacitor at the back of the board. I temporarily replaced it with an electrolytic (I measured the one... - Loading...
