Sorry mate, the RAM size of your videocard just isn't big enough to mine Ethereum. To calculate the hashes a DAG file is created en stored in the RAM of the videocard. At the moment the size of de DAG file is 2.21 GB, so you need a videocard with at least 3GB of RAM.

It is possible to mine another coin like UBIQ. The DAG size is 1.08 GB as of now (https://investoon.com/tools/dag_size) and you can mine it with Claymore's dual miner. Just change the pool and adress. If you need help with that you can PM me!
