Second picture are taken from new personal computer(bottom like N3DSXL, unscrew small plate..) I go to the google and become little confuse? I do not know if such part is DDR3 or DDR3L?(I am find two parts on amazon.. not sure which is..) Other question... I read from internet there is possibility of update "BIOS" of system before install RAM piece? Perhaps I am wrong... I wish to do correctly thing and safe. Thank you for read! Edit: I look more info on computer and can only allow 16GB RAM. Hmm.. How to say.. I think make computer full capability then install all possible RAM.
