Replacing BGA LPDDR3 RAM chips

I have a late 2014 mac mini with 4GB RAM. I already replaced HDD with SSD but some apps, even World of Warcraft can cause the system to hit swap. I use it as a secondary device for macOS experiments and alike from time to time… so I’m thinking about doing a bit risky mod - replacing existing Samsung K4E8E304EE-EGCE 8 Gb x 4 with chips of higher capacity and 178FBGA package - like K4E6E304EE-EGCE which are 16Gb.

Is it technically possible or is there something that would prevent such swap from working?

I would just get a replacement logic board which has the max memory this system can support Mac mini A1347 (Late 2014) Core i5 1.4 GHz Logic Board

Replacing the the chips is very risky! You need the proper tools and skills, you also need the schematics and board views so you can adjust the resistors so the chips are recognized. Without the documentation you’ll have a hard time figuring it out.

If you don’t have the tools and have never worked with BGA chips this would be a foolhardy endeavor.

@danj Yep - you need the schematic to reconfigure the resistor so it knows if the rMBP/MBA provides a clue.

It's not as simple and magical as people make it out to be - this is not a job for the first timer!


Thanks, I was afraid it's more than just the LPDDR chips :) I'll see what's the local board market.
