If anyone here has an Pi4B with these setup, would you please reply with how many units you have running, at what Mhz, and what your CPU usage is?

I'm trying to determine how many I can run on a Pi4B.

Thanks

12 no issues all over 300 GH/s

Thank you for your reply. I've spent some time today trying to get like 20 of these working on a Pi4.

PSA for others wanting to scale up on the Pi platform, while the CPU usage is low there appears to be a limit of around 12 devices on the USB 3 ports (including any hubs you have). So I'll have to run 2 Pi4 units to take advantage of the power savings vs. trying to run so many of these on windows (which uses tons of power / cpu and generates heat).

Pi4 might be overkill for it if you're trying to save a couple bucks. You can probably get away with a Raspberry Pi 3B+ which is a bit cheaper and just SSH into it. I haven't tested 12+ sticks on mine yet but i think it should handle it no problem. I have a Pi 3B+ Model A that i'll try out and report back on.

Well a compacF is around 5 or more times the speed of the older NewPacs.

So one compacF needs the same work generated and written to USB as about 5 NewPacs

i dunno if it's 100% the higher hash rate. Obviously don't know anything about the actual code but i think there might be some sort of USB input limit on the Pi's. A while back I tried running like 20 Newpacs off 1 Pi and wasn't able to. Even if I maxxed em out, i still think that's 2-2.6 TH. I'm getting like 3.5-3.9 TH/s off 12 Compac F's.
