I have a SiFive system, and I’m trying to determine the main memory specs (e.g. speed, number of channels) on the command line. My /proc/cpuinfo says,

```auto
processor : 0
hart : 1
isa : rv64imafdc
mmu : sv39
uarch : sifive,u74-mc

processor : 1
hart : 0
isa : rv64imafdc
mmu : sv39
uarch : sifive,u74-mc

```

I’d normally use dmidecode to find the memory specs, but I am not able to get it to work on this system. Can anyone offer guidance, please?

Doesn’t the HiFive Unleashed documentation clarify?
