I dont think you can mine ETH or ETC any more with 2gb cards. DAG too big.
yes you can.
my 2 gb 380 nitro is still mining eth in a win7 rig. it only will mine in a 3 or more card rig though.
may depend on card position, manufacturer and/or driver version.
Weird.
All my rigs with 2gb cards cant create DAG.. no matter what miner i use.
They do mine EXP fine tho... but not ETH/ETC
Card position shouldnt affect dag size
