    ma’af bos, vcore kayaknya normalnya 1,4v bukan 1,8v. kalo vcorea smps gak akan kerluar jika ic smps belum mendapat perintah dari RAP, Jadi fokuskan dulu syarat kerja RAP, dari hasil cek diatas RAP belum boot karena karena SDRAM belum mendapat vdram 1,8v, coba cek resistansi mungkin ada short. Menurt pemahaman saya begitu bos, Klo ada yg salah mohon koreksinya master, maklum masih nubie.
