Improved 3GB Nvidia GPUs support!
Ethash epochs till 241 are supported now on 3 GB GPUs systems which have at least 3017 MB free - tested with Linux system and Xorg consuming 2 MBs. DAG file generation is slower for epochs 235-240. About 4 minutes on x16 PCI-e or 20 minutes on x1 PCI-e. Epochs before 235 are mined on 3 GB cards as usual.
What we have now means it is possible to run Ethereum Classic which is on epoch 239 right now. We've checked - and yes, It works. Will work for current epoch and the next one until 2 January so you have a chance to mine Ethereum Classic on 3 GB Nvidia GPU in 2019. You can even do make this with PascalCoin in dual like in 2017.
All other miners don't support such experimental feature so looks like nanominer is now the last hope for 3 GB cards mining Eths. Current release will work until epoch 241. Current Ethereum epoch is 231. Epoch 241 will start approximately at 8th of February.
In short: our miner is the only known Ethereum miner for 3 GB Nvidia cards that will work till 8th of February.
