PCB serial number explanation Asrock rx5700xt Taichi oc+

[Oneye]

I was recently taken advantage of purchasing this “Like New” Asrock Taichi Rx 5700 xt Oc+. I want to see if this card can be salvaged.
1. Can anyone confirm this PCB if so how did you?
The card shows ups in GPUz as a lower tier card so I’m wondering if it’s a lower tier card with Taichi plastic or is it just flashed with a different bios.

You might also notice the torn contact on the pcie connector. So before I look into send off the GPU for someone to repair I just want to verify the board.

If anyone can suggest a person to restore the card would be great. Possibly re-ball, test the memory, look for power issues etc..

Character of the card: Doesn’t allow the PC to Post w/o holding pressure on the board. I have been able to get the card to run “Time Spy” picture quality is horrendous! Lights and reflections constantly flicker, the screen tears, blinks.
The card is really dirty so I don’t believe it has been recently disassembled. I think it was in a mining setup and flashed with a bios that was compatible with the task at hand.
It might comeback alive, hopefully it’s just the solder has cracked and just needs some good ole Lead solder.

This is my first post in this forum, I hope this is the correct location.

Some more pictures of the GPU.
It was sold to me as “Used - Like New” According to Newegg it was maybe an open box and been used but should come with everything like new. My thought was that it was better than “Refurbished”. The seller offered to return half my money and I keep the GPU. I figured that’s better than returning the GPU and be out a card and money. Surprisingly I received half my money back but I’m still out $100+

ASRock Radeon RX 5700 XT Taichi OC+ Review

The ASRock RX 5700 XT Taichi OC+ is the fastest factory overclocked Navi card we've tested so far. We measured it to run almost 2 GHz real clock on average in our real-life, mixed gaming load. Temperatures are good, too, and the cooler includes idle-fan-stop.

PCB seems to be valid (AG1903 REV.1.01) for your model. Guess someone flashed a wrong bios on the card after abusing it.

Thank you, Now I can start looking for someone to refurbish the card.
I can do thermal paste and thermal pads,,,, maybe bios swap if I can find the right one. But,, I’d really want someone that knows what they are doing to make the board repairs and re-ball the card.

maybe bios swap if I can find the right one

Here is your official bios: https://www.techpowerup.com/vgabios/?did=1002-731F-1849-5103-C1

Please follow the instructions of eidairaman1 for flashing your card. Only flash with amdvbflash 2.93 and not newer.

Get amdvbflash 2.93
https://www.techpowerup.com/download/ati-atiflash/

Then look for Version 4.68, underneath 4.68 you will see a link to show older version, click that and you should see version 2.93

Here is a fix to make 2.93 work in Windows 10 and 11, Get the zip for version 5.0.567, extract it, then find the AMDVBDriverInstaller, execute the file and follow prompts, then restart the computer, that should help with bypassing Win8 Security feature prompt, if you get that prompt hit ok. Once done flashing run the file again to uninstall it for safety reasons

Follow these steps carefully:

1. Open your "C:" drive in Windows, create a new folder, call it atiflash.

2. Extract the contents of atiflash_293.zip to the "C:\atiflash" folder

3. Find the bios file you downloaded and rename the bios file to 5 digits with .rom on end Example RX 580, change file to rx580.rom (r****.rom)

4. Move r****.rom to the "C:\atiflash" folder

5. Open the start menu, type cmd, when cmd.exe appears right click it and hit "Run as administrator"

6. At the command prompt type in cd\ and press enter until only C:\> is on the screen.

7. Type in cd/atiflash and press enter, you should see C:\atiflash>

8. Type in amdvbflash.exe -i to identify the gpu you want to flash with a 0, 1, or 2)

9. At the C:\atiflash> prompt type in
amdvbflash.exe -unlockrom 0
(there is a space between the e and -unlockrom and 0)(0 is the number zero)
press enter and you will be prompted that the "ROM Unlocked" (or 1, 2)

10. At the C:\atiflash> prompt type in
amdvbflash.exe -f -p 0 r****.rom
(there is a space between the .exe and -f, and a space between -f and -p and 0).
(Or 1, 2)

Press Enter

Follow directions on screen and if flash is successful exit the command prompt and restart, windows should show up on screen.

He denied the card. “sorry 5700 is not worth repairing anymore.” Correction NWR_Tony said this. I got Northwestrepair LLC confused with Northridgefix.

I did get the card working. Changed the pcie in the bios to 4.0 x8 x8
The torn contact was pin 82 (side A) GND. (side B) PETn15 was in good shape. From what I understand the system checks pin 82 to post in x16. So it made sense to just run the card in x8 to verify that the card even works.

Latest Gpuz showing it in 4.0 x8 and min & max temperatures when running Time Spy once. (I run Time Spy because I have data from when I originally built the PC years ago.)

Well you now know why i suggest nrf, not nwr, besides nwr complains in his youtube videos.
