https://bitcointalk.org/index.php?topic=4978579.0 has a miner that is not limited by the DAG size. It uses paging to the system memory from the GPU RAM to get around the issues. I've run it without issues. Performance is slightly degraded due to the hit to get to system memory but it is only 5% slower than what it used to be.
1. This mining tool is a scam/virus.
2. Now the DAG file for Ethereum is 2.66 GB you have another 6 months for mining with those cards if you install Windows 7 or ethos or any other linux based mining software. After that period you can move to Ubiq or other coin
It is going to take a while to convince people that TerraCotta is not a virus. If people have gone through the pain of reverting to Windows 7 from Win 10, just try mining on a fresh Win 10 install on a with new wallet and new everything else. You will see that there this is not a virus. And you can continue mining ether for a long as it makes sense without worrying about DAG size.
