1  Alternate cryptocurrencies / Mining (Altcoins) / Re: Charting ETH vs ZEC Mining Profitability on: June 10, 2017, 05:46:31 PM
Because there are a million or so old GPUs like the Radeon 7970/280X which people bought and kept during the Litecoin mining days. That card performs very well only with ZEC and cannot mine ETH properly due to DAG memory limitations.

That's interesting. I hadn't realized that.
2  Alternate cryptocurrencies / Mining (Altcoins) / Charting ETH vs ZEC Mining Profitability on: June 09, 2017, 11:22:31 PM
Over the last month, daily mining profitability for ETH has more often than not exceeded ZEC. This has been a function of the rise in the price of ETH and a significant increase in ZEC mining difficulty (which far exceeded the relative increase in ETH difficulty). It is now more profitable to mine ETH and buy ZEC, than to mine directly.

Which does beg the question: Why has the ZEC network hashrate remained so high? I would have expected an equilibrium of sorts between ZEC and ETH profitability.

Chart below for the equivalent of three GTX 1070 cards: 90 MH Ethash and 1.2 KSol Equihash.

Let me save you the trouble - you can only get 6 nvidia cards working unless you go to a server mobo with 2x processors.  We put extensive time in testing with H81 and Z97 gaming 5 + pcie splitter.  It's an issue with the amount of memory / pci lanes available.  If you do get it to work somehow, please let us know.  Good luck.

Bunch of FUD here. I've got several working rigs with 7x GTX 1070 or 7x GTX 1060 on MSI Z170 Gaming Pro Carbon motherboards.
