I asked in Telegram and got this about 4GB.
Due to the transition of ETH to a new era, the DAG file has grown in size and does not fit on most video cards with 4GB memory. Because of this, there are problems in their work, namely:
- Freeze or reboot of the miner with the error of inability to write the DAG file.
- A lot of incorrect shares, or an abnormally high hash rate (40-70 Mh / s)
At the moment, in order to return such video cards to work, we can recommend the following:
- Update Hive to the latest version using the hive shell command:
hive-replace -y --stable
This is necessary because Zombie mode may not work correctly on AMD drivers 17.xx - 19.xx.
- Select PhoenixMiner in the flight sheet, and add to add. miner parameters are the following commands:
If after that the cards still do not work correctly, you can specify the exact daglim parameter, for example -daglim 4064, and decrease the value by 5 points until all video cards work stably.
