Researching multi-psu use I came across this post which specifies the best PSU's are DUAL CONVERSION PSUs that convert the entire energy into a 12V single rail. The cheaper PSU type use the 5V line to regulate the voltage, instead of the 12V line like the dual conversion models. That causes voltage instability from not loading 5V line. The EVGA G2 and P2 650W and up are dual conversion models. https://bitcointalk.org/index.php?topic=1761303.msg17827649#msg17827649 |

I just 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 for about $50 in parts at Lowes. 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. You could also use 1/16" angled aluminum pieces if you want to save money. |

Make sure the 8-pin CPU connector is plugged in to the motherboard from the PSU.

I have the same RX 480 cards running in Windows 10 and the 17.5.2 drivers. All you should need to do after modding the BIOS is run the pixel patcher to bypass the signature check. https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-PatcherI would uninstall the drivers in safe mode using DDU, install the drivers and run the pixel patcher before you reboot. |

The potential hashrate of your card is mostly dependant on the POW algorithm used. Some mining algorithms like skein or SHA3-Keccak scale better for GPU mining than others like neoscrypt or yescrypt. That's why you get different hashrates for different POW algorithms. Mining coins that use the same POW algorithm should give the same hashrate.

The MSI 970 GAMING only has 4 PCI-E slots.

So I just started mining Zcash again and Zecsuprnova is not updating the rewards.  0.0099 is the value I had when I stopped mining zcash months ago. Its been 2 hours and its not updating. The hashrate is correct though, and updates every few seconds. The Dashboard can be slow to update. Look at the transactions page under the My Account tab for the most recent transactions posted. |

I want to order 6x Sapphire AMD RX480 Nitro+ the ASRock Fatal1ty Z87 Killer will be rnough for it ?? and what Supply for it 1000W will be good ?
Depending on if you are dual mining or not a 1000 W platinum rated PSU is sufficient for up to 7 RX 4XX/5XX cards per rig with bios mod and will save you money in the long run over a gold. |

Actually, if you run the AMDGPU-PRO drivers, you CAN mix them in a rig. The Fiji card may perform slightly worse than with fglrx, but it works.
Since AMDGPU Pro drivers only support GCN3 or newer cards, I couldn't get it to work with my Pitcarin and RX 480 rig on Arch Linux. I had to switch to Windows 7 to be able to use all my cards  https://wiki.archlinux.org/index.php/Xorg#AMDThe support is labeled "experimental" but it IS there. The "experimental" support for GCN1 and 2 cards is for the open-source AMDGPU driver, which doesn't support AMD APP-SDK OpenCL for mining. The proprietary Catalyst drivers on Linux don't support the Polaris cards and the proprietary AMDGPU PRO drivers only support GCN3 and up cards. The Catalyst ReLive drivers on Windows do support GCN1 and up cards. Uh, don't feed me that bullshit and tell me it's candy - you don't need the APP SDK, only the open AMDGPU driver and SOME libs from AMDGPU-PRO. I know because I've run my 290X side-by-side with my 480s/580s. I tried to get it to work using the Catalyst drivers and open source AMDGPU driver on Arch Linux and wasn't able to get the Pitcarin GCN1 and RX 480 cards working together on the same rig. Besides the driver not suppoting both cards, It's also the Catalyst Pitcarin driver requires Xorg <1.18 while the AMDGPU Pro drivers requires Xorg >1.18 and downgrading the kernel. https://wiki.archlinux.org/index.php/AMD_Catalyst#Xorg_repositoriesIf you have a way to get it to work I would appreciate it. |

With a 100% ROI of 2-3 months on average, ATM GPU mining is a no lose proposition as long as you don't mind dealing with the noise and heat. Trading is a good option for those with limited funds or space to setup a mining operation. The risk of trading/holding is large price fluctuations and the coins you buy could go down and you may be stuck holding the bag. With mining you always have the hardware that can be resold.
Bad exchanges are also a risk, but it can be minimized by sticking with reputable exhanges that have been around a while and only keeping what you can afford to lose in your account at one time. Overall I have made more profit by trading and holding than mining by far. The hard part is knowing what to buy.
What exchanges do you recommend? These are the top top 5 (in no particular order) that I came up with...Since I'm in the U.S., prefer U.S. based exchanges. Poloniex kraken bitfinex GDAX Bittrex Any of those would be a good choice. There is aslo Cryptopia that is good for new coins and it's been around a while. https://www.cryptopia.co.nzThere have been many exchanges that have come and gone since I began in Crypto in 2014. The few I lost coins on were from not paying attention to the warning signs that were there. https://bravenewcoin.com/news/36-bitcoin-exchanges-that-are-no-longer-with-us/ |

ETH is going Proof of Stake at some point, *probably* this year sometime - at which point there are over 29 THOUSAND TERRAHASH (this amounts to about 1 MILLION GPUs) worth of GPUs plus whatever gets added between now and then that are going to be looking for new homes, which is going to HAMMER profitability on every other coin that CAN be mined by GPUs (mostly the higher-profit by AMD mineable ones, as most ETH is probably being mined by AMD cards) - at which profitability for GPU mining is probably going to drop back down to the ballpark it was in 2 months ago even if the current coin PRICING stays high.
So if this is the case, what would you recommend as far as ASIC vs. GPU vs. buy/hold vs. trading? ASICs - special purpose so old equipment can't be re-purposed - almost no resale value. GPU - cards and MB can be resold without taking too much of a hit. buy/hold - simple, but one is hoping the currency goes up. trading - 90% of traders lose money. Exchanges have a history of being hacked. With a 100% ROI of 2-3 months on average, ATM GPU mining is a no lose proposition as long as you don't mind dealing with the noise and heat.

Intel Celeron G3260 is a good CPU option for a LGA 1150 board: https://www.amazon.com/gp/product/B00VDWJZAUA 64GB SSD is plenty for Windows or Linux. If you want to run smOS, you could get away with using a flash drive. |

HI i am very new to mining I would like to mine dgb but am having major problems with setting up cg miner sgminer pretty much every miner I've tried has had some issue . I have an ad radon rx 480 8gb does anyone know a user friendly miner and pool any help would be appreciated thanks .
Digibyte is a multi-algo coin. If you are solo mining, you have to set the mining algorithm to use in the wallet digibyte.conf file to one of the options. Like explained here: https://bitcointalk.org/index.php?topic=408268.msg10194594#msg10194594algo=scrypt
algo=sha256d
algo=groestl
algo=qubit
algo=skein You then can start the miner with the algorithm you chose and point it to the machine running your wallet RPC server. CGminer is a scrypt and SHA256d miner only. With SGminer you can mine any of the Digibyte algorithms. If you are mining at a pool, you need to use a pool that is mining the same algorithm as the miner algorithm you choose. |

If you are looking to build a 6+ GPU rig, the best cost per hash and power consumption is with the 4GB RX 470 / RX 570. ~900W at the wall for a 7 card RX 570 rig is possible with bios mods. The VGA memory brand only affects how easily the card overclocks. Most prefer cards with Samsung or Hynix memory which uses high quality chips that overclock well. With the lower priced 4GB RX 470/570 you have a better chance of getting a GPU with a lower tier brand memory, but it really isn't much of a factor.
Thanks for this, it's really what I wanted to know! What about the differences between 470/480? If the difference in price is minimum, what is the best choice, and why? I still see some 470 at the same price as the 480s and I really don't know why! Thanks! The difference between the RX 470/480 is the memory clock speed and typically better cooling on the RX 480/580. The RX 470 has around memory clock speed of around 7000 MHz or less and the RX 480 uses a 8000 Mhz memory clock. As I said earlier the cheaper RX 470 will have a better chance of using a lower tier memory brand. After bios mods, the difference in hash rates is around 5% - 10% between the two. If you can get the RX 480/580 for around the same price, go with that. |
