Hello,
I have couple of rigs and a question/issue for each of them. I will appreciate if someone can give advice.


Rig 1) 6 x RX580 8GB - since couple of weeks I started having problems with ETH. I have updated the drivers as they were pretty old. I have been using Claymore for a long time with no problems. I have read that it's no longer the best option, so I tried Phoenix miner, which I am using on the other Rig already - latest ver.5.4c. It starts, connects to the pool and at the end of the creation of the DAG, it gives this error:
I could not find solution so far. I have increased the virtual memory to 54000, just in case, the drivers are the latest version, the phoenix miner is the latest version. Any suggestions what could be causing this?

Rig 2) 8 x RX580 4GB - started having issues with mining ETH couple of months ago, tried Hive OS - it was working fine for a while, started having problems again.. so I gave up. Now mining ETC under Windows, but it's barely covering the electricity costs. What are you mining now with the 4GB cards? I have read about workaround - putting 1 x 8GB card in the primary slot and then having the rest 4GB - is that working?
