I'am new to zcash mining.

I've got 325 Mh/s / Sol/s with one R9 290 and less power consumption compared to ETH Mining. Good?

You can do much better. Hawaii seems to respond extremely well to tighter timings. Here are two threads to get you up to speed:

You should be able to get 350-380 with a reasonable core clock / undervolt, more if you then decide to push the core.

Wow, I've flashed the ROM. Now I've got 362 H/s with less power consumption and (only) 947Mhz core clock.
The RAM got tighter timing, but changing the Memory Clock (for example from 1250 to 1100Mhz) doesn't change my hash rate.
Only clock rate influence it. Why?
