I couldn't find the bios to disable the onboard rams. But I found the motherboard schematics and boardview, to disable the onboard rams I removed the RC160 (10K) resistor on the left side of the processor and put it on RC164, and removed the RC161 (10K) resistor and put it on RC165, the onboard rams were disabled. I installed 16GB DDR4 ram in the ram slot and it is working fine now. I am posting it here in case someone else needs it.

If the laptop turns on but there is no picture or constant restart, you need to disable the on-board memory.
This is how the resistors should be installed11-27-2024, 01:18 AM -
I have a lenovo thinkbook 15 g2 itl (working!) and in the .bin bios file i found the lines with 6.5.6.5...6, but i don't know what to replace with 00 to disable the onboard ram/memory, if someone can help.
i've attached the extracted .exe file, this contains the bios dump when opened with 7zip (the file is DOSFLV34_QS.bin)
also how to flash the modified bios? can it be repacked and flashed?...
