Hello, I have a problem.

I bought a used Shappire RX 470 4GB OC graphics card (samsung memory) and it turned out to be broken (displays artifacts). I suspect that it was used in a cryptocurrency miner so I came up with the idea of uploading a new bios to it. The only one I found was: 113-349PS-U41 and the original was loaded: 113-349S4-U41. So I thought it was worth a try. I started ATIFlash and then it happened... I forgot to make a backup file (I know, I know im dumb) and loaded a new bios. From now on, I am unsuccessfully trying to find the original version: 113-349S4-U41. Now the card won't start :(

Can anyone help me?
 
Can you post pictures of the labels on the back of the card
 
Sometimes they are on the side of the heatsink
 
Label:

I managed to run the system on the second card. Below screen with GPU-Z:

Can we get your system specs please, because the 1st card and second card you are talking about will not match eachother exactly.

So there is confusion here now.

Hi, I could not answer because I was sick. I did not quite understand the question. This is the current view of the GPU-Z card. The second card is Asus RX 570 and is borrowed from my father :)
Do you know where to get the original card bios? and maybe there is another way to revive it? Please help :/
 
Back up your current bios then use atiflash in Windows and download this bios file, run atiflash as administrator and flash and reboot.

Here's another that should work.

I have uploaded both versions from your post and the card still does not display the image...
It seems to me that I will have to experiment with voltage. Do you agree? Can I do anything else?
As I wrote, I have concerns that this card could work in digger.
 
You're sure the flash was successful and to the correct card, can you post a gpuz screenshot after you've flashed, booting with the 2nd card that works then choosing the 470 on the gpuz drop down
 
The program showed that the flash was correct. This is the specification of both cards:

Can you physically inspect the vram and confirm they are indeed Samsung. You said in your 1st post it displayed artifacts, now it doesn't display anything or still the same?

Also upload the bios you had on it to begin with so I can have a look at it.

After 1st flashing the card doesn't display anything and so far none of the bios versions has fix it.
Unfortunately, I do not have the original bios (yes I know it was a fatal mistake), but before the flash I made a photo in the ATIFlash and it was the version: 113-349S4-U41
Vram is Samsung. Below the photos of the card (I cleaned the old paste from the GPU and applied a new one) :

Upload the bios you had on it that artifacted.

The 2 I linked you to are literally the only 2 out of 40 for the Sapphire 4GB 470 with Samsung vram and the same device id and subsystem ID that match your card so should have worked....

Unless anyone chimes in with another idea, I'd contact Sapphire support, they're normally quite helpful as I recently received stock bio files for a 580 4GB after raising a ticket.

The problem is that I do not have a copy of this bios with artifacts, because I overwritten it with a new one :(

Check the heatsink you rem9ved from the card for white stickers please
 
Take a picture of the face of heatsink and post it here please.

Also please take a clear close up picture of one of the ram chips please

I'm sorry I didn't write back earlier.

I think it might be:

SAMSUNG 646
K4641325FE - HC28

View attachment 121174View attachment 121175View attachment 121176

Thats good enough.

Ok that is a non platinum card

If your card has a bios switch, do not flash the bios that is working only the broken one

These files may or may not work

The bit I circled looks a bit odd, like it may have been repaired previously.
