Hi All, I have a Gigabyte 1080Ti that has a short on one of the 12v rails. I want to repair it but before I do want to check if the main chip has been killed due to the short. I was gaming and the PC just shut itself off. I have validated with a Multimeter that the short is on the 12v line. How can I confirm if the core GPU chip (in the red box ) is dead? If that's dead i won't bother taking it for repairs. Thanks in advance!
Not sure if it died due to gaming, it died while gaming. My ask was to know if I can validate the core GPU chip on there is dead using a multimeter. I understand fixing it will need a lot more skills and tools.
when 1080ti's go, its usually a vdd rail for the imc, the surge destroys the imc and usually atleast one of the modules.
Yea that pencil mod statement was an illogical and unnecessary assumption made, not sure why. But yea, as you said, stuff does fail sooner or later.
Where did you find the short? How? Measuring SMDs? VRM? Give a try by booting the card (nude as per picture) and check if each memory VRAM is hotter than the others...... Check also the VRMs which one is hotter.... MIGHT HELP:
I used this video to validate the short. On the 6pin and 8pin there should be less than x number of pins that show a full continuity to ground. I can't boot the card as the short prevents the PSU from turning on itself.

I took the card to a shop today who removed the mosfets one at a time and it wasn't one of them. He removed 1 tested for a short if it wasn't gone he put it back and removed the next. In hindsight i realize this doesn't really identify much in the event more than 1 mosfet was bad!
