3 of the 4 screws looks horrible. What did you do to it....
Does your card have dual bios? I think it is the left chip.

Which version of the CH341A programmer do you have? Black PCB or Green PCB with version 1.7 on it? If it is the black PCB, dont use it since it might kill your card further.

This card works on mining and i bought at ridicouls price? memory upgrade at 8gb and bios changed with nitro + modded. flash not possible with amdflash.
Is native sapphire pulse 4gb single bios. i bought ch341A on amazon and arrived ch341 not ch341A (other board are green): I tried on u4521 but seems ch341 is dead.... when i connect gpu to usb, ch341 disconett to pc!!! I'm using ch341programmer 1.3 cause neoprogrammer v2.2 don't see ch341 usb. I'm under WIN10 need to use WIN7?

Is correct, CH341A V1.7 is written on the PCB.

The bios chip of a RX570 4G and 8G models should have the same capacity.

What output do you get with "amdvbflash -i" ?? Please use version amdvbflash 2.93
