I'm getting VRAM problem on Sonoma with a 4600

Hi guys! I'm having problems getting the Vram to work on Sonoma. (it shows as 7Mo of VRAM) Someone told me to use open core patcher to patch. Ive tried using it multiple time but when I reboot the system, it starts loading and then stops and I can't boot the system and need to reinstall. Anyone knows how to get this problem out? Thanks

BTW its my first hackintosh build I'm pretty new to this. If I miss anything or you need more infos tell me and i will find it!
