Do they both have original power brick?   Have you tried swapping PSU's between the two to see what it does?

Just hard to say, not a whole lot of info do we have to help.

RPI is pretty much guaranteed I think with minera.  OP logged in today and did not add anything.... so this thread might be dead without more info.

But my  idea about power bricks I still think has a highly likely chance of being part of it.

Just out of intrest, couldn't you run Minera off an old PC instead of a RASPERi PI

I think you can maybe a raspberry pi virtual box but I cant imagine how much it would cost to run 24/7 compared to running an actual Raspberry pi.
