Hello everyone,
My friend gave me a normal looking RX 460, except he told me that it was having artifacting problems once the AMD drivers installs. Also that the previous owner before him used the card to "mine cryptos". So first thing I do is give the card a good clean and changed the thermal paste. Installed it in my system, disables automatic driver updates and install the Radeon display adapter. Artifacts are gone but now the card still runs poorly (about 1 fps in heaven at low 640x480, 0.5 fps on furmark 640x360 with visual glitches http://prnt.sc/oobmvp). Also, in some programs such as GPU-Z or device manager, text and icons don't render correctly, instead showing as a black rectangle (http://prnt.sc/ooblpa), popping up when I hover the mouse over them. I'm not sure what to do next. Btw I manually downclocked the card to the lowest MSI afterburner allowed me. Downclock did not reduce graphical glitches.

System specs:
R7 1700
Biostar B350GT5
16 GB Ripjaws DDR4
PSU, SSD, HDD, Case & CPU cooler
All system components work perfectly fine when paired with my 1070. No artifacts, no glitches, no black rectangles.

Tried DDUing all drivers, Nvidia, AMD, and Intel. Still does the same thing after installing Radeon software version 19.7.5. Haven't tried any older software, should I bother?

I tried reflashing the card BIOS according to this thread on TPU, but everytime I enter the atiflash -i command I get the error Adapter not found. https://www.techpowerup.com/forums/threads/amd-ati-flashing-guide.212849/

I could try reflowing the solder joints on the PCB, but I don't have the proper equipment. Probably as last resort. Any other suggestions?

Thanks in advance

Update 1: turning ON Virtual Super Resolution in Radeon settings eliminates most of the black boxes, but GPU performance is still lacking. As in 1 fps in furmark. Also has a hard time rendering transparent windows such as the Radeon control panel without turning it into a chess board.

You in luck! I had an RX480 with a bad Vbios and i reflased it using the steps below. ATIflash cannot see Polaris GPUs. That guide you linked is from 2015 before Polaris GPUs launched.

The people at techpowerup told me you have to use AMDVBFLASH.exe.

Download amdvbflash, extract it to a folder, and navigate to that folder in cmd. Then put the new bios in that same folder and type this:
amdvbflash.exe -f -p 0 "nameofbiosfile.rom"
Then hit enter

Can you upload a GPUZ screenshot?

Did everything you mentioned above by the letter. Flash was successful, and I restarted my PC, but problem is still there. Is there any other method I can try?

Update 2: after cranking the power settings in MSI afterburner, both vcore to +100mV and power limit to +12%, and downclocking to 610 MHz core and 1500 MHz memory (after the vbios update) I'm able to run heaven 4.0. Low yields https://prnt.sc/ool7pr and medium gives http://prnt.sc/ool72b. No artifacts at low but artifacts in some scenes at medium, mainly scene 8, 13, 14, 15, 17, and missing textures in 21. Can't increase voltage in MSI afterburner as it is capped at +100, but I have a feeling that more voltage could solve the artifacting. Any way to do so safely? Thanks
