There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

These are my BIOS settings, maybe give those a try: http://imgur.com/a/0zVqwNote: Make sure you enable onboard LAN, I disable mine on accident but forgot to take updated photos. Side Note: There shouldn't be a problem. I was able to replicate this on 3 more rigs full of 7 GPU each all same parts. They are all using Windows 7 x64 Ultimate Edition. |

I will give it a try later this week, have time finally to play around with it. I'll post updates on my findings to see if 8th GPU can mine without any special bios modding. |

So what is the total cost of this project?
I forgot, everything was bought brand new right when the RX480 debut, so on the top of my head, each reference rx480 8gb costed about $230 (including tax), multiply by 7 GPU = $1610 just for the GPU's alone. The rest of the parts you can already know their prices since they are common parts used for mining rigs. |

Crypto currency enthusiast and miner since 2015. Mined approx 200 ETH during 2016 and 2017 and sold it at approximately $US40 each. Then I watched it reach $1000+ each. If anyone bothers to read this stuff pay attention to this: HODL HODL HODL HODL HODL HODL
I started mining with 1 AMD 7950 and 1 R9-280X. Then I gradually built my AMD operation into 12 R9-290s. Awesome ETH hash but ridiculous power consumption and heat. Over the last year I defected to the Nvidia team. I now use GTX 1070s. They were expensive to buy (probably a bargain now) but awesome hash rate vs. power consumption. blah blah blah blah

Hi all
Because there is real problem on the market with mobos. H81, tb85, tb250 and other cheap mobos for mining always out of stock i was wandering maybe there is some chance to buy some normal mobo for around 50-60$ that has 2 or 3 pcie slot and use 3in1 pci hub for run 6 or 7 gpus on this mobos. Is it possible? And if yes someone can advice some cheap motherboard dor this job?

Love your setup!
It looks like it's safe to power a 6+2 pin PCIE off the CPU2 connector on the PSU?
I just built a 7 GPU frankenrig but the standard PCIE cables from the EVGA 1300W don't fit in the CPU2 slot. They have a notched end on one of the 12v connectors the prevent you from plugging into the CPU2. Thankfully one of my GPU's is a 470 so I'm just using the a 6 pin PCIE branch to power it.
Building a second 7 GPU rig now and I really like your setup.
Where can I buy a PCIE cable that will fit in the CPU2 slot? Assuming the CPU2 slot can be used to power a 6+2 PCIE.

I custom-made that cable for him, so PM if you want info.
It's a good thing keying keeps you from plugging a standard GPU 8-pin into the CPU jack. You can't really tell with EVGA's monochrome cables but the pinouts are also very different. The GPU connector has 5 grounds (mostly on the clip side) and 3 hots, while CPU has four hots (all on the clip side) and four grounds. To make one fit in the other would probably result in disaster.

Yes, my cards are the reference models so the rom is from that thread. That is very cool ,7 GPU working on one computer.

As mention in the original post, frame came from spotwood. You can see a link to his website from the original post. |

I don't have any experience with Nvidia's. For AMD, I needed to run the 6x mod for my windows 7 to see 6+ GPU's, not sure if there are any restrictions for Nvidia or not. I was planning to try 7 1080's onto the same rig and post updates, but waiting to see what Vega is all about first. |

Has anyone tried using a pci-e hub in slot 2 (x16) and using 8 GPU? All I've seen on this thread is pci-e hub on slot 6 (x1). I don't think it would matter because they're all connected on x1 lane, but who knows?? I want to run 8 not 7 but need some ppl out there to make sure
also, which mobo do you all have:
h81 pro btc +, or
h81 pro btc + r2.0
