needed help with gpu

[remooner]

hello so i have rescued an r9 290 from a friend  he was using it for mining well either way my problem is there is a piece broken off resistor or capacitor i would appreciate anyone who could point me where to buy a replacement for it thanks

see if you can find a spec sheet on the pcb. that should give you a clue as to what you need.

having said that, does the card work?

hmmmm where should i look for it ? there is some stickers on the pcb nothing more and yeah the card works but i am experiencing  artifacts on various games and its kinda random on some games there is none on some others there is

could be heat related. did you try removing the heat sink and cleaning up and reapplying new thermal paste and reassembling? did you clean the fuzz out of the fins of the heat sink?

is that broken chip a regulator? which you may find on an unrelated pcb somewhere? then you'll have to flux it up and heat it and try gently prying on it with a set of forceps or needle nosed pliers or big tweezers to get it off. then clean up the area with an iron and cleaner then flux and heat and replace and flow solder back onto the pcb/chip.

another thing to do with the card is use and after market software product ( msi afterburner ) and under clock the cards ram and gpu, maybe a 100Mhz each. see what happens.

and while you have the card disassembled I'd check for any noticeable damage by water or drink.

( don't pull fan wires out of plug inlet on pcb during disassembley ) ( don't break the wires ).

underclocking doesnt help done it with intervals of 50 until reached 700mhz on the core and 1ghz on vram ,heat wise never seen temps going over 68c,no there is no water damage ,i thinks its an inductor  and i dont have replacement for it cant find where to buy it  D:

card could just be beat.
