help to identify MacBook Pro RAM chip

Hello!

These are RAM chips from my MacBook Pro 15" Retina Display Late 2013, it has 8 GB RAM & there are empty places on board to add more RAM chips to make it 16GB.

Please help me to identify this chip. No proper results in search engines.

Thank You _/\_

@v1ny4 You already know that those are your DDR3-1600 SDRAM IC's. The particular ones in your image are made by Micron. The D9QBJ is the FBGA code and the IC part number is MT41K512M8RH-125:E. (512MB IC's) They are available at places like this Here is the datasheet for the modules MT41K256M16 MT41K1G4 MT41K512M8 DS

Great! Thanks!

So if some other chip says D9QBJ, is it same as one I have ?

6HEI7 is not important ?

@oldturkey03

Chip that says 7BEI7 D9QBJ should work ?

by

@v1ny4 check the datasheet :-) Those are most likely the Micron manufacture codes. For this IC the only real identifier needed is the D9QBJ
