Hello comrades, i have an asus x570e. Card was working without VCORE voltage, changed the enable resistor of PWM controller which is ASP1405I, card came back to life but stopped at code 4d. I tried 3600x and 5800x with couple of bioses. Programmed the bios with flasher and also tried with bios flashback option but no luck. Board has a broken component i dont know what it is, i need your help about the component and error code. Thank you a lot .

Как такое могло быть?

it was just turning on nothing more :)

do you have ssd m2 conected when you receive this code?
memory voltage is ok? >=1.2v

no, nothing connected. Only RAM and cpu thats it. I have all voltages between range, 4D related to CPU also CPU light is on when its happen.

Maybe search for similar boardview try x370 asus boardview or something else. I am new and i cant see photos, sorry. Also, check if vcore voltage is ok and if you have oscilloscope, check pwm signal if normal and if stable vcore and pwm signals. Maybe something else wrong... Measure if enable signal isnt/wasnt shorted previously before you changed resistor, could be bad pwm controller.

Board is working Q codes running. Debug leg also passes dram to cpu and stays there with 4d error code. I cant find anything same from different boards, even X570 TUF does not have it.

The left component is in place, the right one is probably the same. And for sure it's dual mosfets. You can check with a multimeter.

i placed same next to it, card showed same 4d code with or without it.

Can you provide all measures of resistance by ceramic capacitors on HUB X570?

update : i changed the hub with a brand new one. Everything stayed same
