question for you all.
I have 2 cards, one can only have memory clock of 1900 and other can reach 2050, but no matter how I put the command mmclock 1900,2050 sometimes the order of gpus change and it crashes or sometimes the second card donīt receive the parameters of memory clock core clock and etc.
Any idea people?
I set the core/memory clocks with Afterburner. Setting the clocks with Claymore is very unstable and unpredictable for me as well. |

Been here since 2013. This GPU was like $1000. Mined BTC, then LTC, then X11, and now even ETH. Cost $1000 and probably ROI'd multiple times. Ran at 90C for 4 years non-stop. Not a single fault and fan is still running strong. Basically you got to get in early. Like those who mined 50BTC blocks with their Celeron CPUs in 2009.  And those with rigs now will be ready for the next coin once they are paid off in 60-90 days  |

Hi guys and sorry for waking an old thread.
My concern is: Am I good with one 1200w platinum ATX for: Asrock H81 pro BTC, Intel pentinum G3258, 6x MSI RX 580 8GB, 8gb DDR3 ram and 120gb SSD?
or... Should I buy a seperate ATX something like 450w for PSU and 1200w for GPUs?
Also, are powered riser cables neccesary for Asrock H81 with these videocards? I've heard Asroch H81 doesn't need a powered ones.
Thank you guys!!
Yes, a 1200W Platinum is sufficient. You are looking at somewhere around 800W - 1000W depending if you dual mine and undervolt the cards. It's always best to run a single PSU that can handle the draw at around 80% of the rated power for best efficiency if it has enough VGA connectors to use up to two per strand max and preferably one. Using dual PSU's is a cost savings measure on larger rigs since single high output ATX PSU's are very expensive. The PCI-E v3.0 specification allows more power to be delivered though the PCI-E slot. Newer cards draw more power from the slot than older cards and the wires on unpowered ribbon risers are too thin to be used under constant load safely. I would go with 6-pin 1x PCI-E USB powered risers. |

Hey guys, complete noob here. I've made some profit investing in bitcoin and ethereum and have thought about using that profit to start mining. Some questions I have:
What can I get with $30k worth of equipment? How much profit will this turn out per month approximately?
What is the most profitable coin to mine right now? Bitcoin doesn't seem feasible but what about Ether or Zcash or Monero?
How many of you make enough money to live off this? How much money did you put into your rigs?
What are the longterm prospects of mining in your opinion?
I read somewhere here about some new Vega gpu that will be coming out soon...is it worth it to wait for this? If not will I be able to resell my old equipment easily enough?
I realize I've asked a lot of questions and some of these could take a while to give a good answer. If any of you can answer one or some of these questions I'd much appreciate it. Thanks!!!
Right now with mining its like living in a communistic country. Everybody has money to throw at mining rigs but there is a shortage of GPUs to buy. GPUs are sold out for months and months and when they become available they are quickly bought out. I think if you want to start now you can only get Nvidia GPUs like the 1060/1070/1080. The 1070 I think does 30MH/s (AMD guy here no clue on Nvidia specs) however it costs like $400. THere is the 1060 which is cheaper that you can mine ZEC with. Your other issue is finding 6 Slot motherboards in stock. Another issue is finding Risers in stock close to your location. I think the only components NOT SOLD OUT are the PSUs, SSDs, and CPUs. So with $30000 You can probably buy 50 GPUs like the GTX 1070 and the rest will be needed for the Motherboard, Risers, CPUs, SSD, PSUs etc. Each 1070 currently makes $6-7 USD per day TODAY! Tomorrow might be $5/day or $10/day. Depends on ETH price and how fast the difficulty will keep rising. So to answer your questions you should make $325 USD/day. With Nvidia GPUs most profitable coin to mine is ZEC. With AMD its ETH. Generally we can't earn our living long-term off mining. As we all wish we could. My long term prospects being here since 2014 is that our potential mining profits will halve every month from now on. So your $325 USD today, will be $150 USD next month, $75 the month after that and so on... Yes VEGA is coming out however its a flagship model and will be available in small quantities. Will most likely be very difficult to get in stock. And by the time they are available, mining profits will not be the same. You can definetly mine ETH with a 1060. BBT posted a video of the 6 card rig he built with the PNY GeForce GTX 1060 3GB XLR8 OC Edition 165+ GPU 1000+ MEM ~23.5mh ETH and ~268 SOL/s ZEC each @ ~60W per card. https://www.youtube.com/watch?v=1uhSfOpvHks&feature=youtu.be&t=7295At current prices and difficulty, a single 1060 would generate $5 a day mining ETH, while only $3 mining ZEC: https://www.coinwarz.com/calculators/ethereum-mining-calculator/?h=23&p=60&pc=0.10&pf=3.00&d=688153493511427&r=5.00000000&er=0.14246989&btcer=2644.85000000&hc=0.00https://www.coinwarz.com/calculators/zcash-mining-calculator/?h=270&p=60.00&pc=0.10&pf=3.00&d=2420987.28001629&r=10.00627018&er=0.11338000&btcer=2644.85000000&hc=0.00The specialized mining boards like the Asrock H1 Pro BTC, Biostar TB85 and TB250-BTC are the ones sold out. There are lots of motherboards available that will support 5-7 cards. The ASUS Z270 PRIME A / AR has 7 PCI-E slots on the motherboard and is verified to do 9 cards, 264 MH/s per rig if you add two M.2 to PCI-E expansion adapters. https://www.youtube.com/watch?v=pQ-EAunoAqY |

Hi, does anyone know if the 1200w EVGA P2 is enough to power 6x 570 Sapphire Radeon nitro+ 8gb ?
Or is there a better psu to go for? What?
Yes, good choice. You are looking at somewhere around 750W - 900W depending if you dual mine and undervolt the cards. |

You need at least a 1200W PSU for the cards and then use a 750W or 850W to power the motherboard, all the risers and accessories. |

A 650W won't have enough VGA connectors for six cards. If you dual mine get a 1000W as the VGA PSU . If you don't dual mine, I would get the 850W. Use the 650W to power the motherboard, all of the risers and accessories.

The latest word from the Ethereum Foundation dev chat is they will be implementing a POW/POS hybrid model as early as the end of July on testnet. Rollout to the mainnet would be 2-3 months after that at the earliest. https://www.youtube.com/watch?v=E77sdcZZH0s |

If want to mine ETH, don't get the 1080. The memory is not as good as on the other GTX 10 models. I get 25 MH/s. The 1070 gets ~30 MH/s and the 1060 ~24 MH/s and those are cheaper than a 1080. The 1080 Ti gets ~37 MH/s but is $700+. The 1080 is good for ZEC though, I get 550 H/s at 70% TDP. The GTX 1070 is currently the best overalll Nvidia card for the price IMO.
Hi, What model, miner an settings you use to get 24MH/s on 1060? That is a really good idea to get the ITX versions which costs cheaper. Do they have the same hashrate as normal gtx 1060 3gb or they have a smaller one ? I don't intend to resell as with the actual price of bitcoin ROI is just 45 days for such cards. And which is the best ITX version to get ? Maybe I am thinking to go with this idea but I need the best brand, ZOTAC maybe in this area of ITX ?
Won't 3GB will be obsolete if ETH will increase DAG? Also i would vote for dual fan version, cooler and more reliable if one fan dies... Though performance should be the same.. BBT posted a video of the 6 card rig he built with the PNY GeForce GTX 1060 3GB XLR8 OC Edition 165+ GPU 1000+ MEM ~23.5mh ETH and ~268 SOL/s ZEC each @ ~60W per card. https://www.youtube.com/watch?v=1uhSfOpvHks&feature=youtu.be&t=7295Dag won't reach 3GB until early next year. The only problem with the 3GB cards you won't be able to dual mine. |

with what clock speed you get 550 on 1080 ? i only get 460 h/s MSI GTX 1080 GAMING X 8G TDP 70% Core +130 Memory +750 ~550 - ~570 H/s  |

Only use two VGA connections per strand max, no matter the cable type and preferably only one. With three you are running close to overloading the cable and with four you WILL burn up the cable, the PSU or both. If you don't have enough cables to use two per strand at most, you need to get a bigger PSU that has more connections.

Great information, thank you I started my mining career with just my solo MSI GTX 1070 on my home rig, but am looking at making a dedicated miner. Been building my own computers since way back but never made a miner, and my question is about the PCIe slots/speed - Got an older MSI K9A2 CF V2 motherboard I may use to start? (It runs now with 4gb ram and Athlon duo core 3.0/ Win 7 - was retired but mining got me to fire it up to test it. - not my current system) https://www.cnet.com/products/msi-k9a2-cf-f-v2-motherboard-atx-socket-am2-plus-amd-790x/specs/ The card it has is too old - HD 5770 radeon and is a PCIe 2.0 By looking this post over it appears one can run newer PCIe 3.0 cards on these older boards? i.e. the Dell T5500 - Just trying to wrap up my confusion on how PCIe 1/2/3.0 slots make any difference to mining. I'm used to building pc's for.. eh computing/internet/gaming/etc. If attaching by risers/cables - it makes no difference as to the cards requirements for a slot? So if anyone can enlighten me / point me to a good guide, I would be most grateful. Happy mining! Yes, you can run PCI-E v3 cards on a PCI-E v1.1 and up board. I was running a HD 7850 PCI-E v2.0 card and two RX 480's with powered USB risers on a Dell XPS 700 motherboard that had PCI-E v 1.1 slots. The speed of the slot makes no difference for mining. The newer PCI-E specifications are able to deliver more power through the slot, but as long as you use powered risers the card can get enough power without overloading the motherboard. The problem I had on the XPS 700 was the BIOS would not recognize the PCI-E v3 cards on Post. I had to use the HD 7850 PCI-E v2 card in the primary PCI-E slot to be able to access the Bios. Once in the OS, all the cards were recognized and mined. |

TDP > Core clock > Memory clock in terms of power usage.

Yes, you would need to run two instances of the miner. One for the AMD cards and one for the Nvidia cards, so you can specify the cards to use with with the -di parameter and the different pools to use in each.

Unfortunately zcash.flypool.org dangerous pool, Trojans and viruses on it zcash.flypool.org...!
Really? Good thing I use Linux!  |

Thanks.
How about the 800W power consumption?
The GPU's get around 65 degrees Celcius. Any ideas on this number?
Try lowering TDP to 70% in afterburner. That should drop the power quite a bit. You also may need to drop the core for it to be stable. |
