Looking at the Ampere site, it looks like ampere4 is
a 160 core AmpereOne or AmpereOne M system. The "M"
as more RAM channels but only up to 1.5 TiBytes: 1 DIMM
per channel, 12 channels. The plain AmpereOne can have
4 TiBytes: 1 or 2 DIMMs per channel, 8 channels.

I've no clue how much RAM ampere4 actually has, or what
its RAM+SWAP figure is as configured.
