I recently switched mining software, from qtminer to ethminer.
Ethminer has a higher hashrate, but also higher gpu tempratures, and no need for long dag creation.
Ethminer creates the dag file straight to gpu memory, while qtminer builds a dag file to the hard drive then transfers to gpu memory, 30sec vs several minutes.
To use ethminer download from below:
to use ethminer, create a batch file and add this:
setx GPU_FORCE_64BIT_PTR 0 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_SINGLE_ALLOC_PERCENT 100 ethminer.exe --farm-recheck 200 -G -S server1:port -FS server2:port -O Your_Ethereum_Address.RigName
