Right now all of my miners stopped working (2g cards) is there some explanation, I tried reboot but same thing it doesn't work - OpenCL error -4 (0) - cannot create DAG on GPU
It's interesting that I have rig with 4 gpus all 2G and GPU0 works but the others - OpenCL error -4 (0) - cannot create DAG on GPU
Any ideas?
Just hit DAG epoch 90, so by default the miner will allocated enough space for epoch 92, which is the first DAG that is too large for 2GB cards.
Try -eres 0. That should buy you 1-2 more DAG changes. Reality as we have always known, is that 2GB cards won't be able to mine eth anymore quite soon.
