A little help would be appreciated.
I switched recently to mining Zcash from dual mining ETH & SIA. The problem is I can't seem to get maximum from my cards. I have a rig with 4x1070. From what I have been reading they should be able of producing 450 sols each. I get maximum around 420 from 2 cards and 390 from other two.
Cards are ok because all for of them were around 31 MH for ETH in dual mining (450 sia) no problem.
Any advice would be appreciated. OC settings: Is memory important or core or both? Which miner to use for best hashrate? Am I missing something obvious? At the moment I am using nanopool and EWBF's CUDA Zcash miner.
The OC settings are different for ZEC and ETH.
The core OC is the important for ZEC.
I have 440 Sol/s per each 1070 in my rig.
My 1070 performs poorly. It rarely gets above 400 H/s on ZEC and usually runs about 340-360. Terrible. I've tried all kinds of OC settings. It does well on ETH though.
The 1070 gets unstable and stops at +175 core OC. Should I OC memory as well?
By comparison, my 1060 does 290 H/s or better most of the time.
I am thinking we are making some stupid mistake. I can't believe that there is so much difference between 1070 cards. Can one of you with 440+ sols share his setup? Which miner, pool, and oc settings including undervolting are you using?
