Well i have a shipping notice on the RAM, but i still need to confirm everything might work. My questions now: is my reasoning correct in assuming the three chips i've mentioned will probably fit and work? Where can i obtain these chips? A testing document by Intel in which they've tested compatibility of various RAM chips for the specific CPU i'm using:Īnd with a bit of puzzling i've figured out (i think) what each of the 4 configuration settings does: Now what model of RAM should we buy? Apple provides one type in the schematic: The different options of RAM are controlled by a few GPIO lines on the CPU which are either pulled high or low with a few resistors. So this seems to be pretty straightforward. And apparently all models use 1866mhz DDR3, either by Hynix, Epida or SamsungĪnd you can configure the amount of RAM using some config-lines! So all different models of this macbook are done with the same logic board. In the schematics we're off to a promising start
