You gotta hack those bios memory straps and you'll get 31MH/s and you also gotta dual mine with SIA.
Don't mine ZEC with that GPU.

@OP you REALLY wanna mod those bios' and undervolt, you will see big improvement not only in hash but using less watts as well!

You dont wanna mine Zcash because it's Nvidia dominated, there's really no point and more profitable things to mine for your specific card
Usually ETH, its so damn high in price! haha
Also play the smaller daggercoins you can make more as well
Dual mining causes more heat and wear and tear than its worth basically (most people, i included feel)
