I put the original bios back and it works again, extra memory works as well so it's nothing with the board or dedicated memory. Can you double check?
board is: JS478&JS578&JS778 NM-341 REV 1.0
Edit.
Nevermind. Bypassed integrated memory using original bios and a hardware method. RC81 resistor...
Doesn't work. Now turns the light on and off after few second. fan quarter spin. Was working before, I needed to disable ram because of some display marks
Actually now it doesn't turn on. I tried few different BIOSes and not doesn't turn on. Doesn't even jump to 19V on a charger, stays on 5V. Tried to go back to the original BIN, same thing. Everything around BIOS chip is fine.
Possible to fix it anyhow? No image after changing some secure boot keys options in BIOS, clearing CMOS doesn't help and the BIOS above doesn't seem to work. No POST on the BIOS above
