any electrical engineers here?

I have a 1080 strix gamig that I got used for super cheap as a card that needs repairs, it crashes under heavy vram loads particularly, reproduce-able. runs furmark 3d and heaven at low settings no filtering just fine, runs league of legends at 180+ fps avg, but as soon as you turn up to settings or games that use heavy vram it instantly crashes as its loading textures. so I took it apart and low and behold i'm 90% sure there is a missing smd/smt capacitor/transistor.

 

 

 

EDIT: some one posted a good picture for me to see of an identical card and it clearly has a part where mine is missing. I looked for identical or similar faulty cards to buy for parts but I cant find much. I've seen 1060's and 1070's from asus that have what look to be the same part the small capacitor with the 0 on it but im wondering if anybody knows if that same part off of a different model card would work on this or if there is a better way to go about getting a replacement capacitor

Techpowerup tends to have awesome pictures of the cards they review.

 

They have a 8GB Asus gtx 1080 Strix Gaming card, here's the pictures for it (and click on next page for more pics) : https://www.techpowerup.com/review/asus-gtx-1080-strix/3.html

awesome thank you! so the piece im missing is one of the capacitors/transistors with the 0 on it, one of the small ones that you can see is missing in the picture I have taken and circled in the picture I pulled off the web, is there any good way of figuring out what kind of capacitor that is and any good way of getting a replacement? ive looked for broken cards for parts and cant find much of the same model but I can find like a 1070 or 1060 with an identical looking part on the pcb but i'm wondering if I could pull one off of a different model if it would work the same

Anything with 2 terminals is resistor, capacitor or inductor.

Parts with 3-4 numbers on them are typically resistors.

Inductors are usually black or gray.

Ceramic capacitors are usually brown/cream.

 

A part with a single 0 on it is most likely a 0 ohm resistor or in other words a "jumper" link, it simply connects together the two terminals.

So in theory you could solder a very thin piece of wire between the two terminals and you're done. If there's no traces between the terminals a big blob of solder connecting together both would do the same thing.

thank you so much I will definitely try this. that makes sense to me. could I maybe even test this just by sticking a piece of foil between the two and running a benchmark and that way if it goes wonky I can just pull it off real quick

so I did some research and you were exactly right, it is a 0 ohm fuse-able resistor. so im looking online and was just wondering if you would have any idea around what size code that would be or if im on my own for figuring that part out. I want to see if I can buy one so if something is shorted out the resistor will just blow instead of my psu/card.

What about corrosion

I see that, the card had a very small amount of water damage which is likely what caused the original fuse able resistor that was there to blow. I cleaned the board pretty thurroughly with 99% isopropyl. I traded for the card as a broken card for my old crappy OptiPlex system that the guy wanted to use as a streaming pc, so im not super worried about the longevity of the device I just want to see if I can get it running for a few months or a year or something as a project and something to use in my system till I have more money to buy something fancy yknow.
