Since last epoch #83 and a new DAG file, I'm unable to mine with my rigs with 2GB cards.
They all are with 8 cards (270, 270x, 265, etc.) and all stopped mining last night and unable to bring them online since then.
Rigs are with Ubunty LTS 14.04 x64
Variables are checked and reched, driver version is 15.302, SDK is 2.9.1 (tried different, none of them work for that matter). Miner is 5.3 to some of them, updated a few to 7.2, but still getting the dreaded "OpenCL error -4 (0) - cannot create DAG on GPU"
Rigs are with Asrock H61 Del, H81 Pro BTC some with 8GB of RAM, some with 4GB and the common is that none of them work after last night.
Tested with stock ethminer, DAG file is 1696MB and cards are currently mining, so to my observations problem is not with GPU RAM.
Any suggestions?
Try other ethash aalgo please f.e Expanse
