hope someone can help. I use an Antminer U3 on a Raspberry Pi with Minera and CGminer.
When I mine everything with Scrypt-Algo, I get 100% rejected shares. My current pool is ghash.io.
My log looks like:
Rejected 09ffd3f1 Diff 26/16 AU3 0 pool 1 (Low difficulty share)
my config file:
{
"api-listen": true,
"api-allow": "W:127.0.0.1",
"log-file": "\/var\/log\/minera\/cgminer.log",
"scrypt": true,
"scan": "all",
"pools": [
{
"url": "stratum+tcp://multi.ghash.io:3333",
"user": "WORKER",
"pass": "123"
}
]
}
My additional options are: --au3-volt 780 --au3-freq 238
Minera shows a hashrate of about 60 GH/s, Ghash.io shows about 1MH/s in the multipool.
When i change to the bitcoin pool, everything works fine.
Any ideas? Could it be affected by the pool difficulty, i can set on the ghash.io panel?
Thanks in advance
