> I have always wanted to use more RAM chips than my CPUs/motherboards would support, put all the swap on RAM chips, probably also load the whole OS&apps system drive into RAM this way (hint for your board: add an SSD it would load from, single-time on turn-on) and only use a persistent storage drive for my actual data files.

You could create a RAM disk post-boot and then copy apps into it or use it for a working directory.

But you'll be disappointed to discover that virtually nothing benefits from this compared to a modern SSD. Copying files will be faster, but that's about it.

Operating systems are already very good at caching data to RAM. Modern SSDs are fast enough to not be the bottleneck in most operations, from app loading to common productivity tasks.

Even when we all had slower HDDs in our systems, creating a ram disk wasn't a big enough improvement to warrant creating a ram disk for most tasks. I remember reading a lot of experiments where people made RAM disks to try to speed up their development workflows, only to discover that it made no different because storage wasn't the bottleneck.
