Forum rules
Anything about Riecoin mining goes here! A type of topic are threads about a CPU type. Only post your optimal parameters or show your machine in such topic and create a new one if there is no topic about your CPU, following the same scheme as the current ones. Otherwise you can also discuss about things like the profitability in general or other mining related subjects.
Different CPUs models should be discussed on the same topic if they are of the same architecture, have the same number of cores, and the same cache sizes, for example the 2700X and 3700X will have different topics, while the 3770K and the 3770 should be discussed on the same topic.
Do not talk about the mining software (suggestions, bug reports,...), go to the rieMiner's topic for this.
No technical support here as well, go to the Help subforum.
Discussions about current Riecoin mining pools must go to the Pools subforum.

I managed to compile rieMiner natively using the Ubuntu supplied by the manufacturer, basically replacing Arm64 with rv64 in the Makefile & using /proc/cpuinfo for the target switches.
It's a bit slower and less energy efficient than some, but not extremely so. It's using 5 watts. 4 cores run at 1.8ghz, 4 at 1.4ghz. 1.17g used of 3.72g available memory.

Here's how it compares to my other machines:

Rpi4 4x a72 1.5ghz 0.9 ric/day

Rock3c 4x a55. 1.4ghz 0.9 ric/day

Opiz3 4x a53 1.5ghz 0.8 ric/day

Opi4a 8x a55 1.6ghz 1.7 ric/day

OpiRV2 8x KyX1 1.8/1.4ghz 1.2 ric/day
