Miner settings

Since the Equihash (Zcash) algorithm usually prefers a higher core timing than does the Ethash algorithm that is used for Ethereum mining, I also ran a second test run with the core clock set a bit higher to 1300 MHz. I then needed to increase the core voltage to 1050mv too, so it does come as a trade-of between hash/sec versus power consumption. On the plus side, Zcash is not as memory bandwidth dependent as Ethereum, you can lower the memory clocks a bit, or to default in this case, to save a bit of power.
