@ 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. |

I have not seen anyone that has gotten a gpu to work via an M. 2 to PCI-e adapter. The one I got from ebay did not and I was refunded. Not even if the system has only one gpu installed. So except for people that has modified custom MB I don't know of anyone who is has gotten more than 7 rx cards working.
They work. https://www.nicehash.com/?p=news&id=155Of course you enter the problem with power supplies at a high enough rating, in which case it's usually easier to build two rigs with more affordable components etc. A 9 card RX 4XX/5XX rig uses a lot less power than the old R9/280X 6 card rigs from a few years ago. A server PSU or dual PSU setup is also an option. |

Not all motherboards or chipsets support 5+ cards on risers, even if they have the slots for the cards. I believe most of the B250's only support 4 or 5 cards. That's why it's important to do your research and only use motherboards verified to support the number of cards you plan to use. https://bitcointalk.org/index.php?topic=1953113 |

The ASUS Z270 PRIME A / AR is verified to do 9 cards, 264 MH/s per rig if you add M.2 to PCI-E expansion adapters. https://www.youtube.com/watch?v=pQ-EAunoAqY |

OK great - yes, all of the motherboards I have been considering support 6 or more AMD cards, so that's good news. It's hard to find a lot of info about NVIDIA mining as there's so much focus on the much cheaper AMD cards.
Looks like I might actually settle on the Asus Z270-P motherboard.
I would go with the Asus Z270-A / AR motherboard. That's the board BBT used in his 1060 video and he' built a nine card RX 580 rig with two diffrent brands of cards on that board using M.2 to PCI-E expansion cards. https://www.youtube.com/watch?v=pQ-EAunoAqY |

Thanks - I am seeing this as a possible issue now, as it might be tough to get such a variety of cards working.
I will likely move the Fury to my main desktop and build an NVIDIA-only rig, starting with 4x GTX 1070s and 1x GTX 970.
Do I need to find specific motherboards for 6x NVIDIA cards, or is it a safe assumption that motherboards which support 6x AMD GPUs will likely support 6x NVIDIA GPUs as well?
Eventually this will most likely be 6x NVIDIA GTX 1070s, so I'd like to start buying parts for a rig with this in mind.
How many cards the motherboard suppports is limited by the number of PCI-E slots and how the motherboard allows the slots to be configured. I don't have a six card Nvidia rig but AFAIK, no particular motherboard is required for Nvidia cards vs AMD. Just make sure the motherboard is known to support the number of cards you want to use. In fact it's easier to get multiple Nvida cards mining on the same rig than it is for AMD cards. No Bios mods, driver patches or hard crashes. Just install the latest Nvidia driver and it should work. |

Any GTX 10 model would work fine. The $190 PNY GeForce GTX 1060 3GB Graphics Cards 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=7295Hard to beat if you can get it for less than $200. The only disadvantage is with 3GB VRAM, you're not going to be able to dual mine effectivly. The do make a 6GB model. Otherwise the GTX 1070 is the sweet spot in terms of perfomance and price for Nvidia, IMO. |

As long as the motherboard supports the number of cards you're trying to use and the drivers also support the cards, it should work without a problem. I currently have a rig with three diffrent types of AMD GPU's, RX 580/480, HD 7850 and a Nvidia GTX 1080. You also need to figure out which GPU index when configuring the settings for each card in the miner. Having the cards all the same is simpler.

How are people able to get more electricity than what the state allows? I am in Florida and was informed I can only get 200 Amp to the house .
Residential areas often have different rates and service than commercial tiers. |

Latest version is v9.5:
-tt set target GPU temperature. For example, "-tt 80" means 80C temperature. You can also specify values for every card, for example "-tt 70,80,75".
You can also set static fan speed if you specify negative values, for example "-tt -50" sets 50% fan speed. Specify zero to disable control and hide GPU statistics.
"-tt 1" (default) does not manage fans but shows GPU temperature and fan status every 30 seconds. Specify values 2..5 if it is too often.
Note: for NVIDIA cards only temperature monitoring is supported, temperature management is not supported.
Note: for Linux gpu-pro drivers, miner must have root access to manage fans, otherwise only monitoring will be available.
@Claymore: are temps and fan speed available for RX 5xx with latest driver in Windows 10? They display for NVIDIA cards but not for the 5xx series. /c You need a monitor or a dummy plug in the card plugged in the primary PCI-E x16 slot for the AMD drivers to be able to read and set the fan and temperature settings. You also need to change the primary video to the PCI-E slot and not the on board video in the motherboard Bios. |

Profitability calculators only give you estimates based on the most current data. The longer out the timeframe, the less accurate it will be. You can put anything you want for the difficulty and recalculate for various estimates, but nobody knows for sure what it will next week or next month.

The ASUS Z270 PRIME A / AR is verified to do 9 cards, 264 MH/s per rig if you add M.2 to PCI-E expansion adapters. https://www.youtube.com/watch?v=pQ-EAunoAqYThat would lower your costs to 3 sets of motherboards, CPU's, RAM and SSD's. I recently did a build of the BBT mining case below out of two 8ft pieces of 1/8" x 3/4" angled aluminum, one 8ft 1" x 2" piece of pine and #8 1/2" self-tapping screws. The case will fit up to 7 RX 4XX/5XX if you put them about 1 inch apart. For 9 GPU's I would increase the length of the longest frame section by 7 inches from 19.2 to 26 inches and I would also increase the frame height by 2 inches from 9.25 to 11.25 inches, which means you will need to use three 8ft pieces of 1/8" x 3/4" angled aluminum instead of two. https://www.youtube.com/watch?v=D5xNrlxsCVsBBT on YouTube said he will have a mining rig case build video next week with updates from his original video. |

Have you installed the drivers and does the card show up in Device Manager?

I would get a corded drill. You should be able to get one for around the same price. It doesn't have any batteries to charge and will have more power than a cordless one. Here in the US we have Harbor Fright Tools, that sells cheap Chinese tools. You can get an electric drill for $20 or less when on sale and a hacksaw with mitre box combo for less than $10. Gpu's and power supplies can be heavy. If you go with angled aluminum, get at least 2mm thick or 3mm preferably. The 1mm or 1/16" pieces are too thin and the case won't be very sturdy. You should be able to get aluminum angles at a home improvement or hardware store. |

Sweet! Just ordered 7 of those  + 3 off ebay for spares  Build one Nvidia rig and one AMD rig, less problems and easier to handle, i have this way, no compatibility issues what so ever, like others said, gpu config is pain in the a.. if you have mixed them. I have 1080TI running like a charm, i personally would buy only 1080ti-s, easier to sell gamers later: http://mylifegadgets.com/GTX1080TI one makes like 11-14$ per day and 300-400$ per month using only 185W power yeah, but it's double the price of an rx 470 and 50% more than a gtx 1070 ---------------------- How many GPUs would fit in here? http://www.ebay.com/itm/152561445042?_trksid=p2060353.m2749.l2649&var=451960305634&ssPageName=STRK%3AMEBIDX%3AITAlso got this for improvisation purposes of creating a case - 100PCS Self Adhesive Rubber Feet Clear Semicircle Bumpers - 2PCS Grid Divider Tray Egg Crate Aquarium Fish Tank Filter Bottom Isolate Black White (putting in on top of the crate and GPUs on top if it) - 100pcs Black White Network Nylon Plastic Cable Wire Zip Tie Cord Strap ( to secure stuff) It doesn't give the dimensions of the crate. But a RX 470/480 can be up to 30+ cm by ~5 cm thick with the risers. I Don't know if that would be deep enough. I recently did a build of the BBT mining case below out of two 8ft pieces of 1/8" x 3/4" angled aluminum, one 8 ft 1" x 2" piece of pine and #8 1/2" self-tapping screws. The case will fit up to 7 RX 4XX/5XX if you put them about 1 inch apart. The cost of the aluminum angles and screws was ~$35. If you build it out of all wood, the cost would be less than $10. That's a much better design that allows more airflow than using a crate. https://www.youtube.com/watch?v=D5xNrlxsCVsThe only tools needed were a drill with a 3/32" hex titanium drill bit to drill pilot holes and a #2 phillips screwdriver bit. A hacksaw with a 32 tooth blade and a plastic miter box to cut the aluminum and wood. It took about 4-5 hours since it was my first time building one. The case is very sturdy and can support up to 7 GPU's.  |
