Hello,
to my knowledge there is unfortunately no schematic available anywhere for the Mac mini Late 2014 (Macmini7,1).
This is sad because no schematics means it is difficult to repair and even upgrade the ram on those models.
And those models are cheap, consume very low power and are very reliable.
I had a few of them available at my office, in either 4GB, 8GB and 16 GB configurations, and I wanted to upgrade at least the 4GB ones to 16GB ram.
so I decided to take note of the different configurations of the resistors on the motherboard, which change between the different RAM configurations.
This let me change the RAM and upgrade it. The ram is LPDDR3 in BGA 178, the exact same RAM as in the MacBook Pro and Air so it is easy to buy some new in Chinese market places or even to get some from dead logic board.
Here are the resistor configuration I noted. Green rectangle means 10k resistor present, red rectangle means 10k resistor missing.
The location of the resistors configuration is on the upper side of the logic board, at the opposite of the CPU.
1 - resistors configuration for mac Mini 2014 with 4GB SK Hynix Ram
2 - resistors configuration for mac Mini 2014 with 8GB Elpida Ram
3 - resistors configuration for mac Mini 2014 with 8GB SK Hynix Ram
4 - resistors configuration for mac Mini 2014 with 16GB Elipida Ram
If anyone can help me complete this thread with others RAM capacity / manufacturer configurations, it would be very nice.
Nevertheless, I was able to change and upgrade 2x Mac mini 2014 1.4Ghz 4GB to 16GB ram, this is not as fast as an M1 mac but this is nice
