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 goes to RC80 and RC85 to RC84
