    Consumption is same with ram/without ram?

    Have you checked 2.5V rail is present or not?

    Ram reset checked?

    Communicated on SDA/SCL pins of ram slot checked?

    Ram slot pins failure is quite common on this mb-so check under microscope.

      Sorry to be late and thank you

      YES same consumption with or without ram = 0.480 V
      2.5 v is present
      No ram reset , RC32 1.2V from 1 side
      pin 108 ram slot = 0.057v and 0.831 KOHM
      CD92 not exist
      So the DDR_DRAMRST# is not present

      i can t take if SDA/SCL communicate or not

      anything else to check !

        You dont have DSO? If yes, measure atlest voltage on SDA/SCL pins.

        Have you tried touching up the ram slot pins?

        I beleive you tried another ram stick and bios flash.

            Very very likely its SOC fault.
