A Raspberry Pi 4 with 16GB? It’s been done, but there’s a big catch

An intrepid hardware tinkerer has managed to upgrade the Raspberry Pi 4 computer board to sport a hefty 16GB of RAM – in a manner of speaking.

This comes from YouTuber MadEDoctor, who boosted the system memory attached to an entry-level Raspberry Pi 4 from 1GB to the mentioned 16GB, as shown in a video just uploaded to their channel. The upgrade was carried out using a hot air rework station and some very careful soldering.
