30 MH/s for a 1070 is very good. Congrats! |

Seems you don't have enough memory for the Dag. You need at least 3GB VRAM on the card to mine ETH.

This issue has come up numerous times. Each there are some that advocate dividing the cards and their riseers between each of the PSU's. I recently upgraded to a dual power supply setup which had me researching on how to connect them safely. I came across posts suggesting powering the riser and PCI-E power connector on the card with the same PSU. Others say the psu that powers the motherboard must also power alll the risers. The slave psu should only power the PCI-E power connector on the cards. https://bitcointalk.org/index.php?topic=1761303.msg17825999#msg17825999https://bitcointalk.org/index.php?topic=1843586.msg18351224#msg18351224Ultimately, I did follow the latter suggestion as it seems logical the same power supply that powers the motherboard should also power the risers connected to the PCI-E slots on the motherboard. The second slave power supply only powers the 6 & 8 pin auxiliary power connector on the video cards. According to another post I came across that connecting the PSU's that way ensures they share the same ground, which is important.  https://bitcointalk.org/index.php?topic=443540.msg4878774#msg4878774I also noticed BBT in some of his his latest live streams emphatically recommended that when setting up a dual PSU rig, you need to power the risers with the same PSU that powers the motherboard and only use the second PSU to power the GPU's. https://www.youtube.com/watch?v=lXZondkAWVc&feature=youtu.be&t=1253https://youtu.be/pQ-EAunoAqY?t=988I have a EVGA 850W G2 and 750W P2 setup tpgether with an add2PSU relay. The 750W powers the motherboard, peripherals and all of the risers. The 850 W only powers all of the 6/8 pin VGA power inputs on the cards. |

Anyone know how to turn down the core voltage on a 1070? Afterburner only allows a positive change, the slider does not go to the negative territory like it does for an AMD card.
Setting the power limit lower is effectively the same thing. I use 70% with a GTX 1080 and it drops the power usage ~25% compared to 100% TDP. Anything less than 60% losses too much hash. |

Get 580s, they are great for dual mining! I would recommend 8GB Variants as the DAG file gets bigger time by time, 8GB will be long lasting and moreover, they are easy to sell.
The DAG limit is projected to be hit by September 2019, by which the cards will be extremely obsolete for mining and/or Ethereum will have switched to PoS. The 4GB variants are the best value, except for when the price difference is in the neighborhood of 20 dollars or less. Yea, but once the Dag gets over 3GB by early next year, you won't be able to dual mine effectively with 4GB cards. You already can't dual mine with 3GB cards. |

You need to specify the rpc server IP in the configuration file with rpcconnect. That is the IP address you need to use with the miner. e.g. to mine to the wallet running on your local machine use rpcconnect=127.0.0.1. The rpcallowip parameter are the IP's that are allowed to connect to the rpc server. To allow a single IP from your LAN, use your machines LAN IP. To get the LAN IP of the machine type ipconfig in the Windows command prompt and look for the IPv4 address. e.g rpcallowip=192.168.0.01. Cgminer is a Scrypt and SHA256d miner only. You need to use Sgminer to mine skein coins.

If you want to mine ETH go with the RX cards. The RX 460 4GB can do ~14 MH/s at ~50 W per card and some don't require a 6/8 pin connector on the card. https://www.youtube.com/watch?v=-VuPm8N5T0wThe GTX 1060 is another option at around $200 it can do ~23.5mh ETH and ~268 SOL/s ZEC each @ ~60W per card. https://www.youtube.com/watch?v=1uhSfOpvHks&feature=youtu.be&t=7295I have 5 cards running in Windows 7. Two RX 480 ~315 H/s ZEC, 1 RX 580 ~330 H/s ZEC a HD 7850 ~195 H/s ZEC and a GTX 1080 ~550 H/s ZEC. If you mine with GCN 1 and 2 cards (Tahiti, Pitcarin, etc) and want to mix them with GCN 3 or newer cards, Windows is really your only option. The AMDGPU Pro drivers in Linux only supprt GCN 3 or newer cards. There is supposedley a workaround to get the older GCN 1 & 2 cards to work together in Linux using the open source drivers, but I couldn't get it to work. The Windows Crimson Relive drivers support all GCN and up cards. You want a pool that has low latency to you so you have less stale shares and rejects. Use a pool located near you. Modding the memory timing straps in the Bios (AMD only) mostly helps with ETH, which likes fast memory. It has less to no effect on most other coins. You still need to find the core and memory clocks that work the best for your card. If you have diffrent cards, then you need to set each one seperatly. Having cards that are all the same makes it simpler. |

driver 17.5.2 for mix 480+580?
That's the driver I'm using with RX 580's and 480's in Windows 7 and I apply the pixel patcher after installing to bypass the signature check with a modded Bios. I tried updating to the new 17.6.1 after uninstalling the current driver in safe mode using DDU like I always do, but the new driver won't detect any of the cards and won't even install the driver, so maybe they have new type of check before installing the drivers. I just installed 17.5.2 and everything works again. how many cards are you running with windows 7? I have 5, four AMD RX 480/580 and one GTX 1080. |

Been there and done that. Back when I started mining early in 2014 there was an influx of new coins, almost diaily. Mining was good, but not as profitable as it is now. Then ASICS took over Scrypt and X11 and megapools started mining the most profitable coins, just to dump them in to BTC and depressing the price. By the end of 2014 every coin had a negative return when you factored in electric costs or making a few dollars a month. The only way to make a profit was to mine new coins with a low difficulty. The good news is I held on to most of the coins I mined and I'm glad I did.
To me the fact that even with all the new GPU miners, ASICS and farms out there, MUCH more than in 2014, and mining is more profitable now than ever, is a sign the Crypto market is in a growth phase. The new highs, exploding marketcaps and BTC at close to $3K is getting everyones attention and the party is just getting started!

You already can't dual mine effectively with 3GB cards. Once the dag gets over 3GB you won't be able to mine ETH with 3GB cards and be also dual mine with 4GB cards.

Apparently you didn't RTFM either. The motherboard specifications say you should use PCI-E 1.0 in the Bios. http://www.biostar-usa.com/app/en-us/mb/introduction.php?S_ID=865#specification5 x PCI-E x1 3.0 Slot(using for bitcoin mining, it is suggested to change to PCI-E 1.0 via BIOS) You also need to plug in the two Molex connectors on the motherboard. 2 x PCI-E 12V 4Pin Connector(Must be installed when using for bitcoin mining.) |

Did you change the 1x PCI-E slots to PCI-E v1.0 in the Bios? Did you install Windows 10 in UEFI mode?

yes ..choose 2 1070's.
That will give you the 1080ti hash rate.
Thanks for the info all. Are there any coins that the 1080Ti CAN'T mine? It can mine any algorithm supported by the miner. Nvidia GTX 10 is good for Equihash (ZEC) and Skein (DGB). For Dagger coins (ETH) GTX 1080 ti is not as good as AMD RX 4XX/5XX. It can do ~38 MH/s but costs 3x more than a RX 470/570 that can do ~28 MH/s. |

You're not going to be able to build a mining rig right now. AMD GPUs are sold out worldwide. In the past 2 weeks I've called maybe 60 shops looking for cards in 5 different countries. I found 2 RX570s.
Cards are supposed to be back in stock in 2-4 weeks. However, with mining as profitable as it is now they will get sold out instantly. Many of the shops I called had queues for people pre-paying for video cards and lining up to get them.
I got a newegg notification that they had RX 570s in stock. I went to check it out, sure enough they had them in stock with a limit of 1 per customer. It'd take 2 weeks for me to get the card if I ordered from the US. I went to talk to someone to debate if I should buy it or not. I decided to buy it. I went back to newegg clicked 'add to cart' and the cards were already sold out.
Moral of the story: when dealing with hot commodities, buy first, think later.  |

Hello all,
I'm in the process of setting up my first mining rig and am trying to plan ahead as to what to mine etc. The whattomine website only shows 1080 cards. Can I use any kind of multiples to show what the Ti will produce? Or is there another website that shows up-to-date stats and cards?
Thanks,
DE
What ever the 1080 can do, the 1080 ti can do better |

@ op how much did you spend for the six card setup?
300$ for ASRock H81 PRO BTC R2.0 65$ for 9 Risers 1068$ for 3x rx470 (+50$ for shipping forwarding from Italy) 1070$ for 2x gtx1070 256$ for hx1200i PSU (+ around 25$ probably for forwarding the hx1200i from United Kingdom) 53$ for 120 gb SSD 56$ Intel Celeron G1840 Processor 2.8 GHz 25$ 4gb RAM 20$ fans, zip ties, rubber, grid.. I found a local ad for an rx470 pretty cheap, so I planned to buy that one as the 6th one However, no one is yet answering so I'll probably have to purchase +1 online. Anyways, so far total is 2718$ and I have to order one more GPU. + I paid around 70% of the orders in bitcoin which adds up around 4% fees on average, which would come in total over 2800 USD Wow, you paid top dollar for that mobo and all the GPU's. The same rig here would cost less than $2000 if you bought it right. Everything is out of stock currently, only way to get equipment is to pay high :/ For the GPU's I agree, unless you are patient and buy them one at a time. Lots of cheaper mobo's that would work, ASUS Prime Z70-A / AR for one. |
