Guys please: Before you attempt to diagnose GPU for faults, please have the following: #1 Multimeter #2 GPU it self Believe it or not, #2 is often not available.

Thank you very much, you reassured me. I have a computer that fell on the ground while it was working, and when I turned it off after it fell, it did not turn on after that. When I checked it, everything was normal, but the vga circuit I suspected that it had shorts, but after I made sure I found it a small resistance in vga and not outright shorts

Thanks a lot for this guide, it's very useful and understandable. In my case visual inspection looks right, but there is a lot of capacitors in short (3 near the PCI slot connector, and 6 at the back of the core), so I suspect it could be a dead core, but since I'm a beginner, what do you guys think?

If I change the R22 inductors (6xunits) do I have a chance of solving the problem? Is there a way to find out which inductor is bad or should I replace them all? do we have another solution? thank you this noise is driving me crazy!!!

hi, if pex rail resistance below 3 digit (possible short), will the core still getting warm? because my dead rtx3060ti core still warm and getting hotter with all voltage present. I want to make sure the core really dead before I use the card as my door stopper.

PEX rail can have low resistance sometimes. Depends on the card. Unless it's 0 ohms i wouldn't immediately assume it's short.

Where does the „global“ or singel enable signal for the controller come from ? I already replaced a blown powerstage on a 3,3v plane on a saphire 5500 xt. But although i succesfully removed that short i still have no enable signal on any controller. Also i measured 0.4v on the enable pin of the Vcore controller. Wich is according to its datasheet the fault voltage. I need to know where the fault has its roots.
@heinzkot360 Жыл бұрын
Btw all fuses are good and all power inputs are good in terms of voltage. I honestly dont know what the 3.3v rail is for :D and it might help to know where the enable signals are generated in order to seek for another short. Pretty sure the powerstage blew because of another issue

I have a PNY RTX 2080Ti that will boot and the screen will come on and I may be even able to run Heaven for a few minutes but then I get a black screen and the Blower Fan turns on Max. I then have to either do a 5 sec power cycle or turn off the main power to get the computer to reboot. I have noticed that I am missing a lot of ceramic Capacitors on the back of the card. I would begin replacing the capacitors but I don't have another 2080Ti to get them from. What should I do?

I have a 3060 Ti that gives me code 43 so I want to check what is causing it. GPU-Z can read the BIOS, the VRAM frequency, even the driver but not the size of the VRAM. I dont really get artifacting like most common 43 errors, in fact the card works every time I restart PC, it works for like an hour then the screen goes dark and PC restarts. The funny thing is it passes furmark test and gaming, but again it randomly crashes. I suspect maybe is BIOS chip but I have ZERO knowledge of PCB layouts, or how to use multimeter thats why im here lol but any way to identify BIOS chip and how to test it with multimeter? EDIT: I checked ASUS download center for BIOS update on my GPU but it says there are no new updates for it.

Most likely faulty VRAM. Try to run a mats test on it. If GPU-Z can't read the VRAM size that means the driver is not installed/active
