Bought A 290X With A Broken Resistor For My Friend, Thoughts?

post #1 of 18
Thread Starter 
Hey guys, so i bought an R9 290x on ebay for $81.14 including shipping and tax for my friend who's building a PC. He gave me the money, and told me if I couldn't fix it that its okay, I can still take the risk. Link to the ebay posting.
http://www.ebay.com/itm/Sapphire-R9-290X-4GB-GDDR5-Video-Card-for-parts-repair-/282081783108?hash=item41ad626d44:g:d3kAAOSw7ehXShXN

Was is a bad choice? Should I try to lower clock / undervolt to see if it wont artifact or should I attempt to solder the resistor back on? (It's included) I have a XFX r9 390 cooler that should fit on it with some modding. Any tips or advice?

It's always a risk, I've fixed a broken card once and it worked in 2D flawless or almost but in 3D it had various artifacts. And good luck finding out what to replace and with what. Also the SMDs are tiny and pita to solder without heat soldering tool and paste.

Top middle picture you can see the contracts exposed. He said hes including the resistor that fell off.

Claims damaged resistor is stopping a DVI port from working which is plausible.

Yet the card clearly has other issues, he says other outputs "work" *yet* have artifacting.

He also mentions the card shows up in device manager without drivers which is expected, why mention this? Probably because it doesn't show up *with* drivers installed.

AKA its the typical "it will be an easy fix for someone that knows how" which translates to this card is beyond reasonable repair and has more than one broken resistor on the DVI port.

Doesn't even include the cooler or the PCI bracket which probably means its been hanging around for a year in bits and he has lost the parts. But hey he is including a resistor... which probably means he tried to repair it too.

These people boil my piss, they know their item is junk but are happy to rip people off with claims of "easy fixes" and such.

On a related soldering note, your average cheapo soldering iron won't touch this. The PCB sucks up the heat applied faster than you can melt solder.

Great points you mentioned. I wont be using the DVI Port, and i have an soldering iron specifically for doing work on PCB's etc. If anything this will be a great project card if anything. Maybe the artifacting can he fixed by some underclocking anyways.

Ive had the card for a day now and wow.
1.) It will not boot to windows with drivers installed, it will go to safemode
2.) I tried soldering the resistor but its like as soon as the solder touches the air it hardens.
3.) I tried seeing if it would work as a crossfire card. Imma try to BIOS mod it and lower the mem clocks and core clocks akd voltage.

Does anyone have a PCB / Datasheet for the 290x?

regarding SMD soldering, you need Solder paste and a heatgun.

Paste the contacts, lay the SMD resistor, gently heat the area with the heatgun, the focused heat of the heatgun can't be wicked away by the masses of copper in the PCB, and the paste only takes a few good seconds to work.

I hope you get it fixed though!

EDIT:

you also have to ask yourself, how the hell did that resistor fall off, did he drop the card? Did he jam at that resistor with a screwdriver?

The issue is my resistor flew off somewhere and I have no idea where I could get one, or if maybe I could try something else.
