Hell there, i have a RX5700 from XFX that wont be recognized from System. PC wont postup... Power is on, but no picture and no loading OS - nothing.
Voltages all fine, vcore, vMem, soc, vddci... All here. I also flashed the BIOS with spi flasher - but nothing. GPU gets fast Hot when turn on PC. What can happened here?

Same issue here with two 5700s, I think at this point it's either the core itself or one of the memory chips.
