Getting Low Hashrate with Antminer U3 on Raspberry Pi ( minepeon)

[Skvrahul]

Hey guys,
I recently got myself an Antminer U3 (63 GH/S) and initially when I first got it I started mining using my PC But recently I thought I'd hook it up to my RPi and mine on it using minepeon.
When I used my PC initially I ran CGMINER on it and managed to get an average of around 60 gh/s on cgminer.
But now when I connect to RPi I cannot manage to get more than a MERE 5 gh/s. :/ can you guys help out and help me fix this please?
Thanks in advance!

the u3 is flaky   use it with an r1 not a raspberry pi


go to crazy guy's threads

read how the antminer r1 is great with an u3

start here   mikestang is a decent guy as is crazyguy

Have you ever raised the hashrate? I'm still getting about 15GH/s with the following instructions:

sudo cgminer/cgminer --bmsc-options 115200:0.57 -o stratum+tcp://us-east.stratum.bitcoin.cz:3333 -u xxx -p xxx --bmsc-voltage 0800 --bmsc-freq 1286

They an best and most stable on 225m and 775v. But the U3 is a tempermental beast. Ive got two of them and tried running them on the R1 but it would only pick up one of them. Ended up running them both on cgminer and today one of them would only hash at 20-22ghs. Was running fine this morning when I got hom eit was running at that and kept getting the error about it not giving hashes after ten seconds. Ive now put the problem one back on thr R1 and so far so good. Average is at 55ghs. Its probably to do with crazyguys firmware keep resetting it. Saves the hassle and keeps it working, just a shame I couldn't get it to see both of them regardless what I tried to do.
