Hi,
Using this miner with old R9 280x in single mode.
When I mine altcoins I get 20 mh.
But when I mine Etherium I get only 10 mh.
Why???
What altcoins were you mining? Different coins have different algorithms and different speeds. If you were mining another ethash coin (Ethereum classic, Ubiq, or Expanse) and getting different speeds then there might be an issue.
Ellaism(ELLA) for example...
The DAG file of ETH is large. So it is slow.
So there is no sense to mine ETH with this GPU? Only altcoins?
280X is slow for DAG over 2GB, no fix yet. DAG for Ethereum is more than 2GB so it is slow, better mine other coins.
