RX 470 Problem 43

It started while I was trying to overclock the Radeon software ... While everything was fine, slanted lines appeared on the screen and the computer froze. After forcibly turning it off, when I turned it on I noticed that the resolution has decreased and that annoying vertical stripes have appeared that occupy part of the screen. On "device management" the card showed error 43, the monitor was at 64Hz. On GPU-Z the card frequency was 0. Important values were unknown. Please help me

There's a chance you damaged the video memory or the GPU core itself if you cranked the clocks and especially the voltage too high. Or it could be as simple as a corrupted BIOS.

If you haven't already, try reinstalling your GPU drivers. Do a "factory reset" when reinstalling.

If that doesn't work, you could try reflashing the BIOS. Take the cooler off, get detailed pictures of the GPU core, the memory, and any stickers on the card so we can find the correct BIOS.

I checked: the bios has not been modified ... I just overclocked and stressed the card too much ... Regarding the GPU drivers, I have already tried to reinstall them but without success. Thanks a lot anyway
 
Hello.
From what i saw in those pictures i can confirm that you have damaged the memory chips from the card.
I have one card that makes the same errors and i went with it to a repair shop where they confirmed the damage.
Sorry mate
 
Now, if you can find someone who can do board-level repair, it is possible to replace memory chips on GPUs.

But then you'd need to source replacement GDDR5 chips, and I don't know how difficult or expensive that is.

I'm destroyed. Thank you so much mate
 
You either have luck to find a board with GPU dead, but i would suggest to search on Ebay or Aliexpress for those chips.
Open the card, make a picture of those Chips and start search the exact code as you have

Now I'll see what to do ... Thanks a lot

O hai la fortuna di trovare una scheda con la GPU morta, ma suggerirei di cercare su Ebay o Aliexpress quei chip.
Apri la carta, fai una foto di quei Chip e inizia a cercare il codice esatto che hai

Ok I will. Thank you!
 
Here's a video that shows the process of replacing memory chips on a GPU.


Find someone who knows their way around a hot-air rework station and get some memory chips from eBay or Aliexpress.

EDIT: Found someone who did a memory upgrade on an RX 480, so that's even more relevant to your situation.

Need system specs, what vid input are you using on the monitor, output on card?

Did you just buy this card?
