No data on availability or price available that I've found.
Also, why did they put SLOW MEMORY on a "mining" card?
This thing better be LOW COST if they expect it to sell - though given current "availability" issues, they probably will get away with it even if it's not for a while....
It's based on the RX 470 4GB which has the same memory clock and is already the best cost/hash mining card on the planet. |

Make sure Virtual RAM is set to at least 16GB. You could also see if changing the PCI-E lanes to GEN 3 in the Bios helps.

I don't think it's a smart move now to invest fresh in mining , this time is to get your roi faster with what you already got , if you have only one rig then stick to it and don't invest more , because as i said it's not the right time to invest or buy new machines .
I disagree. The ROI timeframe now is shorter than it's ever been. If historically low ROI times are not when you should build rigs, then when is a good time? The key is not overpaying for the cards and not put yourself in a position where you are overextended if the market turns. |

Yes, I do the same thing. Claymore dual mining ETH with the AMD cards and EWBF mining ZEC with the Nvidia card. You can select the cards to use with Claymore with the -di parameter in command line or config file.

Using for years without issue two PSU setup connection marked at Your drawings as "not correct". My opinion is opposite, of course:
- I know for sure that there is no power connection between motherboard and riser. Therefore I can freely use different PSUs for motherboard and GPUs.
- I don't know for sure is there power connection in GPU between it's PCI-e slot and PCI-e power connectors. So I don't mix PSUs to power riser and power connectors on single GPU.
You are wrong. I checked the outer pins on the USB cable that connects to the riser from the 1x PCI-E slot with a multiimeter. There was 3.3V coming from the motherboard. There is also a ground connection between the riser and the motherboard. |

There is no guarantee of profit in mining. Even with the explosive growth in mining equipment, profit from GPU mining is at an all time high from the high in BTC and explosive market cap growth in alts. It's predictable that at some point the market will normalize and the profits will not be the same. What GPU mining has shown is that it always prevails as new coins and technologies look for new ways to leverage the huge adoption that GPU POW mining has and that is only likely to grow in the future.

It makes more sense than switching over because your hash rate will decrease in 6 months.  The market probably just over reacted to the FUD and there is the Nvidia factor. It's not a single issue. Yep, and the biggest one being there are no AMD cards for a month now. Vega release is going to very interesting. |

It'll probably increase as some eth miners likely saw the hashrate drop articles and panicked, switching to Zcash. It'll likely continue as ETH becomes less and less viable to mine on.
The hashrate drop for Polaris is largely overstated. My reported hash for seven cards went from 202.7 to 202.2 MH/s. with the new epcoh. I think it has more to do with the fact that AMD cards have been unavailable for a month now, resulting in large numbers of Nvidia sales which do better on ZEC than they do on ETH. Do a simple benchmark with Polaris on claymores. The drop increases as the epoch keeps increasing, so its 0.5mh between 129 and 130, it will be 5mh between 130-140 and 15 in 140-150 etc. In 6 months more than half of all Polaris owners will have switched to other algos. Benchmarks are just an estimate. When I ran my own benchmarks on Claymore the figures were overstated. Claymore's benchmark for a 5 card RX 480/580 8GB and RX 570 4GB rig showed a 0.8 MH/s drop between epoch 129 and 130, from ~143.3 MH/s, at epoch 129 to 142.5 MH/s at epoch 130. The actual hashrate for the 5 cards was 144.1 MH/s and that was dual mining with DCR. For 7 cards, the actual epoch hash drop was less than 0.1 MH/s per card while dual mining. People also mine ETH with 1060's now at ~23 MH/s and 1/3 of the dual mining performance of the RX 570 4GB. https://bitcointalk.org/index.php?topic=1977653.msg19727441#msg19727441 |

I think it has to do with memory clocks on the cards. AMD RX 580 clocks top out at ~2100 MHz, while Nvidia clocks run at more than 5000 MHz.
so ETH requires more the core clock which is close between the cards, ZEC uses both (core + memory) and there Nvidia comes in advantage because of high memory clock. wondering if some miners could be optimized for core that AMD cards can raise their S/s. Actually ETH runs better with a lower core clock speed compared to ZEC. It also must be something about the difference in memory architecture. My MSI 1080 Gaming X will do ~560 H/s on ZEC, but only ~25 MH/s on ETH. The difference is the 1080's use GDDR5X, while the 1070's use GDDR5 like the RX 580. The 1070's also run at a higher core clock compared to the RX 580's. ZEC is core count and speed dependent so Nvidia does better at it. ETH is memory bandwidth and speed dependent and so AMD's lower core count/speed does not impact it much. The memory numbers you see reported as 7000 or 8000mhz are just 4x of the actual memory clocks of 1750-2000mhz. Both AMD and NVIDIA use essentially the same GDDR5X memory - similar chips similar clocks. The RX 4XX/5XX use GDDR5, same as the Nvidia 1060/1070's. The Nvidia 1080/1080ti's use GDDR5X memory, which is different than GDDR5. In January 2016, JEDEC standardized GDDR5X SGRAM.[2] GDDR5X targets a transfer rate of 10 to 14 Gbit/s per pin, twice that of GDDR5.[3] Essentially, it provides the memory controller the option to use either a double data rate mode that has a prefetch of 8n, or a quad data rate mode that has a prefetch of 16n.[4] GDDR5 only has a double data rate mode that has an 8n prefetch.[5] GDDR5X also uses 190 pins per chip; (190 BGA).[4] By comparison, standard GDDR5 has 170 pins per chip; (170 BGA).[5] It therefore requires a modified PCB. https://en.wikipedia.org/wiki/GDDR5_SDRAM |

BBT uses this board a lot in his builds. He also has a video walkthrough of what you need to do to get the Asus Z270-A / AR running with 6+ cards. https://www.youtube.com/watch?v=DR-FkpU2KfINext he's going to try 13 cards on the board using a PCI-E splitter! |

On a hash per cost the 1060 is better than a 1070 for ETH. Two $230 1060 3GB cards will do ~44 MH/s on ETH using 60W each at 60% TDP and cost the same or less than as a single 1070 that only does ~30 MH/s on ETH at double the power consumption of the 1060.
Hm... Is it possible to find GTX1060 for $230 now ? Not as easy as it was two weeks ago, I guess the word is out. Actually $230 is overpriced from what they were selling for a month ago. Lots of overpriced 1070's for $460 are still available. |

The RX 580 will do ~315 H/s on ZEC. The Claymore epoch benchmark figures are just an estimate and largley overstated. In my own test with a five card RX 480/580 8GB and 570 4GB rig. The benchmark at epoch 129 for the five cards was ~143.3 MH/s, at epoch 130 the benchmark was ~142.5 MH/s. The actual current dual mining hash is ~144.1 MH/s dual mining with DCR. Even a 10% drop in the RX cards ETH hash in 6 months can be offset by addding a single $200 RX 570 4 GB card.
Where does the huge difference on ZEC mining coming from between 1070 and rx580? At ETH a GTX 1070 has similar MH/s than the RX580 but at ZEC it has 50% more (~ 480 Sol/s). From gaming perspective they are also very similar from performance. And yes, this is a serious question as i'm interested in technical details due to my work in IT business  I think it has to do with memory clocks on the cards. AMD RX 580 clocks top out at ~2100 MHz, while Nvidia clocks run at more than 5000 MHz. |

....as my new rx580 are coming...if it gets bad is it a good idea to maybe switch to zcash?

Card Type: Nvidia 1070
Memory: 8 gb
ETH Hashrate: at stock 26 MHs // tuned 30 MHs
SIA Hashrate: at stock 250 MHs // tuned 300 MHs (i don't know how many ppl are mining at 500mhs with tuned 1070s)
Power consumtion: 140 Watt ~
OS: Win 10
with oc on memory you can do 32MH on 1070 not only 30, 0r 29 in dual mining, it's the best thing you can get for a non-amd gpu on ETH, 1060 is not good, the bus is too low and not good for ETH On a hash per cost the 1060 is better than a 1070 for ETH. Two $230 1060 3GB cards will do ~44 MH/s on ETH using 60W each at 60% TDP and cost the same or less than as a single 1070 that only does ~30 MH/s on ETH at double the power consumption of the 1060. https://www.youtube.com/watch?v=1uhSfOpvHks&feature=youtu.be&t=7295 |

Powered risers draw about 40-50W each. Never use SATA connectors to power the VGA power inputs, only use PCI-E 6/8 pin cables and never use more than two SATA or molex connectors per cable to power risers. You also need to get a power usage meter. For ~$20 they are a necessity to help you manage the rig efficiently.
