I'm not sure what motherboard you're using, but if you're using powered risers, then a mining-specific motherboard should not need the supplementary power from the 4-pin molex connectors. With my setup, I used all of the available PCIe power connectors available directly off of the PSU (no splitters), then I started using 2x molex to 6-pin adapters. I have heard of 8-pin EPS 12V to 2x 6(+2)-pin PCIe adapters, but haven't tried one out before. If you end up using SATA to PCIe adapters, I would recommend using the 2x SATA to 1x 6-pin adapters over the cheap 1 to 1 adapters that probably came with some of your risers. Something such as this one would probably do the trick: https://www.amazon.com/StarTech-com-SATPCIEX8ADP-6-Inch-Express-Adapter/dp/B007Y91B80I would avoid powering more than one riser off of a line of SATA connectors, but that's just me. SATA connectors are not rated for the same current that 4-pin molex or PCIe connectors can handle. DO NOT, REPEAT, DO NOT use Sata or Molex to power GPU's. Unless its a really low end GPU that can function without the PCIe power and has the plug just for overclocking etc. Molex cables are rated at 75W, Sata cables are rated at 50W. A normal PCIe would draw a MINIMUM 75W so both are unsited. OP had the right idea with using splitters on the single cables. Stick to 12 cards only with that setup, or go for a PSU that gives you more connectors, most 1000W+ give you 8 PCIe connectors. I never use EVGA for the lack of connectors. |

A motherboard that has been designed for mining specifically will be by and large the most hassle free and the easiest to setup for mining with 6 or more GPUs with the least troubleshooting, hair pulling, and downtime. We came to the decision that at this point we won't use anything other then dedicated mining boards. Down time is lost money, let alone the aggravation of dealing with it and losing that time to do other things that need to be done.... they just aren't worth it for us at least.
In my year and a half of experience, Mining specific motherboards have given me WAAAY more trouble than regular or gaming motherboards. I prefer the latter because of the ease of setup ( for a total newbie it may be more complicated to setup a non mining board, but once you know your way around a few bioses, its fairly straightforward ) and stability, because their availability is much better and because prices are much more reasonable. Sure in the long run maybe the mining board has better components that would last longer, but I doubt it seeing the cheap ass thin pcb's and lack of features on both Asrock or Biostar (I own 20+ of each btw so I speak from experience). Suffice to say is, if one of the reputed motherboard manufacturer make any mining boards, I will buy them without skipping a heartbeat. I await the Asus mining boards for now. |

Claymore v10.0 + AMD 23rd Aug Blockchain Drivers = Stable.
MSI AB beta settings keep getting reset, other watttool like utilities also suffer the same fate.
Uninstalling/Removing all tools and using Claymores built in ccore cvddc etc settings, and setting hash target is working fine for me for now.
I read claymore mention its a problem with the AMD ADL and it (may) be fixed if there ever is another blockchain driver update, or if this "fix" finds its way into mainstream drivers.
In the meantime, does anyone have a better solution to getting under-volts stable on Windows? The whole reason I was on windows all this while was the low low power consumption a simple tool like watttool could enable, now I might as well switch to smOS or something.

Hi,
What to mine if RX 480 and 580 are unavailable ?
I am interested in etheruem but as i see the post 4GB card going to useless after some time and 8GB cards are very expensive
Now what should late comer mines ?
Also suggest low cost cards , In my local shop i can only find nvidia 1060 6GB card and nvidia 730 4gb , what to mine with this ?
Thanks
GTX 1060 6Gb are good cards to mine Ethereum, Zcash or Monero, any crypto currency. The Nvidia 730 is shit though, please avoid it. but with 1060 i can only recover cost in 10 months and also very power hungry Thanks Power Hungry??? Its the most power efficient mining card on the market. As for ROI, what did you expect? 2 month ROI? Why would the manufacture sell any cards then, why not keep them and mine themselves? |

A friend of mine asked me if can advise him on motherboard choice, that will work with 6+ cards, i am not familiar with majority of boards and cant advise him on this, perhaps someone from this forum can... here is the list:
GIGABYTE GA-Z170X-UD3
ASUS Z170 PRO GAMING
ASUS TUF Z270 MARK 2
MSI Z170A GAMING M7
MSI Z87 POWER MAX
It will be nvidia miner with 6 cards at least.
thanks
Tell him to get almost any z270 board that has 6 physical slots on it, and it will work. |

Holy Moly ... this really is getting absurd. Even without the "Risers" that motherboard has 22 PCIe slots. How are you going to connect 19, or 22 or 104 GPU's to one motherboard? How will you design a lattice around the motherboard and the PSU's that are almost equidistant, since longer USB cables cause issues. This is beyond practicality now. |

Shoutout to creepas, I saw this at his page http://blog.invictusmining.com/  The biggest Pro that I see is : 3 x PSU Headers on the board mean you do not need to externally link the PSU's, you can directly connect them to the motherboard and they will all be started together by the motherboard. That, and the reduced hardware costs and cheaper OS/monitoring service - only one copy of ethOS, SmOS MinerstatsOS needed so the fee is one third. Ofcource I personally haven't even crossed 8 GPU per board for fear of stability, and to avoid multiple PSU's and the complexity they bring. But this makes me want to get one just to experiment with it  Once again, would request our asian friends to keep their eyes peeled, and let us know when these show up in retail. |

Maybe because they dont exist? This some guy posting links spamming all threads, he may have blocked these domains and have plans to launch the websites, noone knows |

So you are an expert in mining and bios modding but are completely new to Bitcoins so hence your "Newbie" account?
Shhh ... just send them your monies and hope they shoo away the DAG slowdown  |

Hi My rx470 4gb that 28.3 to 25.6 mh My rig that 162 mh to 157 mh Why?  ?? Since you appear to have been living under a rock for the last month or so, I suggest you catch up on research now. Never too late. Google it. |

Update 7/28/2017 All GTX 1060 Gaming (Micron Mem) Current Settings/Clocks + Hashrate:
Core Voltage = *
Power Limit = 50
Temp Limit = 75c
Core Clock = -100
Memory Clock = +500
Fan Speed = %75
1GPU Dual Mining stats 90/10:
ETC: 22.5 MH/s, PASC: 75.125 MH/s
8GPU Dual Mining Combined stats 90/10:
ETC: 180 MH/s, PASC: 601 MH/s
Wattage at the wall:

Dont dual mine with Nvidia. You lose more profit from the reduced ETH hash than the secondary coin will get you. |

BACK Y'all........................ been so busy with so many things in life. Have lots of exciting things to share..................just need time to gather the stuff, upload,etc. I wish Bitcointalk have a newer interface to allow easier uploading without needing to transfer to imgur first, etc.
Cant wait ... |

She wanted people to know - otherwise, I never name my sources. You don't do that (usually) or they stop doing you favors 'she wanted people to know' ....  right, now I believe you When Wolf0 AND Claymore tell you something, you believe it son. |

hey guys..
I have no idea what to do in that OS, so please help me to configure that
I already configured the ETH address and pools ..
1.How to change the mining rig name
2.How to overclock my GTX 1060 cards
3.How to install team-viewer or something to connect remotely ( not putty )
4.Ill have 10 GTX's and 2 AMD's in that rig, is there any config that i need to do to start all GPUS ?
Thanks
ethOS has extensive guides on their website, and a solid support chat/channel. Use it. |

I talked to 2 fan sellers, they both said that there was no different between 70% and 100%. If this is true, I would like set the GPU fan speed to 100% to make GPU cooler, what do you think about it?
Yes, fans could die in only 3 years instead of the usual 5. The real question is, does it matter? |

The DAG epoch issue: it seems AMD fixed it for Vega in drivers and now they are working on Polaris. New drivers will be available soon, may be in two weeks or so.
I highly doubt this - not that Vega doesn't have the issue (I would hazard a guess the massively different memory controller fixed it without them needing to try), but them fixing it for Polaris - ESPECIALLY in that time frame, doesn't sound right to me. I'm not going to call it, because my sources haven't gotten back to me on this, but I don't think so. I admit it - my gut was wrong. My owner has confirmed - issue is due to large page sizes, and since AMD now knows what the issue is, a fix is probably in the pipeline after all. Interesting how you worded it ...  |
