always buy 6 gpu at least you can maximimize your density and income with a single rig, running only 4 when you can run 6 is losing potential profit, for the mobo it's better to wait for the new asrock pro btc h110 that cna handle 13 gpu, so you build only one rig and expand for the future
Ok,can't run on windows,it only see's 7 GPUs at most...what OS see's 13 GPUs?? And how much is this wonderboard?? Good question. I believe Linux can handle any number as long as there are enough PCI-E lanes. In the ASRock demo they had a 13 card rig, but only 8 were running on Windows 10. Given the price of they're other mining boards, it should be ~$150. https://www.youtube.com/watch?v=EpksFaxkbPk |

I modded the bios successfully and increased the mining speed to ~14.xxx mh/s with the following settings:
If the speed is at 14 MH / s then what is the power consumption? I'm interested that, because 560 costs half price 570.  Yeah, I want to know too. If it's half of 570's power draw, that will be good. About 40 watts each after undervolt and no 6/8 pin PCI-E power connector required. About 80 MH/s for 6 cards and 550W at the wall. https://www.youtube.com/watch?v=-VuPm8N5T0w^^^^^^^ That's actually for the RX 460's, but the RX 560's should be very similar. |

The number of slots on a motherboard doesn't mean they will all work with GPU's and risers. That;s why it's important to stick with motherboards that are known to support 6+ cards.

After the fallout of the DAO fork, ETC was opposed to the fork, so it continued on the original blockchain. The two chains are independent of each other as of the fork, so ETC will remain unchanged if ETH moves to POS.

The problem with AMD GCN 1 and GCN 2 series cards on Linux is the newest AMDGPU PRO Linux drivers are only compatible with GCN 3 and up series cards. https://wiki.archlinux.org/index.php/Xorg#AMDOn Windows the Catalyst ReLive drivers support all GCN and up cards. The best solution I found to get GCN 1 & 2 cards mining in Linux is using the Catalyst 15.9 or 15.12 drivers, which are the last drivers before they moved to the AMDGPU PRO drivers and they actually work better for the older cards than the current Windows driver does. The other problem is the Catalyst 15.9 or 15.12 drivers don't support Xorg 1.18, so you have to use an older distro. I got it working on Arch Linux using the Catalyst Total package in the AUR after setting the Xorg 1.17 repo in the package manager configuration file as instructed in the Arch Wiki: https://wiki.archlinux.org/index.php/AMD_CatalystFor a dedicated mining rig, you could also use the smOS R series distro, which is based on Linux. https://simplemining.net/ |

Sounds like the driver is crashing. Try backing off the GPU core clock by 10 MHz and the GPU memory by 50 MHz, or you could lower the intensity.

It depends on what plans you have for the rig. If just want to start mining as soon as possible, as mentioned a 650W would be plenty for up to 7 460 cards. Stick with EVGA or Corsair Gold or Platinum rated models. The EVGA 650W P2 is a great choice for under $100: https://www.newegg.com/Product/Product.aspx?Item=N82E16817438055The EVGA 750W P2 or G2 is also a good choice and it comes with twice as many VGA ports. Once you upgrade to better cards you can daisy chain a second PSU and have less out of pocket than a single larger PSU. If you want to wait, RX 570/580 should be more available in a week or two. If you want to use Windows, an OEM license is available on eBay for less than $5. Any cheap 64GB SSD is enough. If you want to use smOS, a flash drive is sufficient. Gotcha....so the OEM license. Is that buying just the license and me already having a install disk. Then during the instal when it ask for the license key I enter that one in? Also can I run 7 cards on the 650w P2 PSU? I probably will only run like 4 or 5 at first but just wondering how many physically I could run, not wattage wise as you said it would run 7 When you buy the OEM license on eBay, the sellers provide a link to download the ISO if you don't have one. You can use that to create a boot flash drive using Rufus. If you plan on using 6+ GPU's, you must install Windows in UEFI mode. Make sure to select GPT disk for UEFI from the Rufus menu when creating the install flash drive or you can select the cd UEFI boot in the motherboard boot menu. The RX 460's without the PCI-E power connectors should use less than 50 watts each as BBT shows in the video. How many cards you can put in a rig is limited by what the motherboard supports. Most motherboards have less than 6 PCI-E slots. The ones that have 6 or more, do not always work with that many cards or are a pain to setup, so it's important to stick tp motherboards that are known to support 6+ cards. You also need to get a power usage meter to check how much power is being used by the rig and make sure it's efficient. https://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU |

So in order for this to work, must I patch the driver BEFORE restarting, immediately AFTER installing the driver? As in if I already have the latest driver installed, I must uninstall and then reinstall WITHOUT restarting to patch the driver?
You should be able to patch the driver anytime after installing. If it doesn't work, try uninstalling the driver in safe mode using DDU first. |

The HD 7XXX series is the cutoff for the current Crimson Relive AMD drivers, so compatibility with modern coins and miners will be very limited. Something like Monero would be about the best option.

I wouldn't rush to buy less efficient GPUs due to the current ether price. You have less room to mine if the price takes a dive.
Yea, but with the entry price of $120 - $140 per card, no 6/8 pin required and 50W per card, a 650W PSU would be plenty for up to 7 cards. The GPU ROI is still only 2 months. You can always upgrade the cards as more options become available, sell the 460's for at least half the original cost and resuse everything else. |

There are scrypt and X11 ASIC miners and they haven't been profitable to GPU mine for years. Even more ASIC's are coming online from the most recent surge in LTC. Neoscrypt coins like FTC are profitable with GPU's, but there are more profitable options to mine, like ZCash and ETH.

None of those except ETH are profitable to mine with GPU's. With the current ETH pricing, it makes sense to mine with older cards, especially if your power is less than 0.20 cents /KWH. Even a RX 460 card rig, which are cheaper and more readily available would be profitable. https://www.youtube.com/watch?v=-VuPm8N5T0w |

Yes. Select the CD UEFI boot from boot menu or create a boot flash drive with Rufus using the ISO. Make sure to select GPT for UEFI bios as the partition type in Rufus.

With all those rigs your going to need to pull out the hot air using a squirrel cage fan so that cooler intake air can replace it. Otherwise your just circulating the hot air in the room. It's also more efficient to pull hot air out than push cool air in.
