This has nothing to do with mining altcoins and you worry too much.

The last Nitro+ RX 580 8GB. I bought from Newegg was last month at $279, which is about what they had been going for from online retailers. I bought several others over the last 6 months from Newegg and others. The highest price I paid was $289. The current price is almost double what I last paid.

It's not that calculator are wrong. Profit calculators are just showing profitability based on what you would receive if you cashed out the coins you mined at that moment. They can't predict what the profitablity will be the next day, the next hour or at the time you sell your coins. If BTC goes to $25K in 3 months or the coin you mine appreciated substantially before you sell, your ROI time frame for the coins you mine today will be much lower than what the calculator shows you, which is based on current profitability. Obviously if BTC or the coin you mine crashes, then the opposite is also true. You also have to account for the mining difficulty increasing over time cutting in to the amount of coins you can mine, but that is usually much more predictable than what the price will be in the future.

Actually as usual with all of your glib statements, they are factually incrorrect and outlandish. The Etherum difficulty increase since the beginning of the year is closer to 20% and still is a long way from the peak of difficulty reached during the ice age when ETH was sub $300 for most of that period. https://etherscan.io/chart/difficultyIf you want to hear what someone with more experiece and preparation thinks about the outlook for GPU mining in 2018, including Etherum mining, BBT had an excelent dissertation this evening. Very informative and highly worth watching. https://www.youtube.com/watch?v=Y53rpCyeeRc&feature=youtu.be&t=1330 |

That is a SHA256 coin the same algorithm as BTC, which means it's ASIC only. Trying to mine with a CPU/GPU would be an waste of time and unprofitable. A CPU has 1/1000000 the hashing power of a SHA256 ASIC miner. https://bitcointalk.org/index.php?topic=331394.0 |

Looking at the sticker on the back MIGHT provide a clue  |

Damn, that's one more thing to test!
So...flash all your cards with the aggressive timings (from 1500 MHz) and identify the ones that aren't stale, then reflash those with a more conservative BIOS?
In my experience with RX 480/580 and 570's, cards with Hynix and Micron memory are stable with the 1500 MHz straps. With Samsung cards you need to use the 1750 MHz. |

I'm seeing Vega and the nvida branded cards all have blower style fans now
Should we be looking for blower fan gpus vs the 2 and 3 fan gpu,?
well basically custom heat sink are better so 2 and 3 fan gpu cards can be way cooler and last longer specially for mining in the long term i have few turbo 1 fan 1070 and 1080s they reach 74 or even 80 easily because they only have one fan. So why are all the official video card makers AMD and Nvidia making blower styles now for their flagship models? If 2 or 3 fans are better then 1 in cooling why have AMD and Nvidia crippled their flagship line up? I sit here with cash in hand trying to figure it out. I have an msi areo 1070 that's a blower style. The only thing I think it does is keep everything cool. I hear the 2 and 3 fans the heat stays around the case and makes all the components really hot.. the whole card gets hot where my gpu is not hot to the touch So now if after market 3 fan gpus are better then Nvidia which has been the best permorminl Because the goal of a reference design is to demonstrate the capabilities of the new architecture. Blower style coolers work across a variety of configurations, where open fan designs might not. Developing optimal coolers also takes away from their R&D capital without changing the underlying architecture, which is why it's more of an aftermarket thing left for partners to develop. |

Other than what's been mentioned and in this video, you can try another pool. I think the fixed share difficulty that Ethermine uses is too low for the 15 second block times since the Byzantium fork, which causes too many stale shares. I switched to Nanopool that uses a higher share difficulty and my estimated hashrate on Nanopool is much closer to my reported hash rate. https://www.youtube.com/watch?v=MpzE1k73JY4 |

To overclock using Claymore, use the latest Adrenaline drivers and put the parameters in the config file or command line. Also set the GPU's to compute mode in AMD settings and reboot. You can adjust the core/memory clocks/voltage, power limit and temp/fan speeds using Claymore. Verify the settings using HwInfo.

If you want to use the compute drivers, Afterburner will not work with AMD Crimson 17.11.xx or 17.12.xx drivers and multiple cards. Either use the Claymore config file to apply the overclock and undervolt settings at runtime, or use OverdriveNtool to create overclocking profiles for your cards as explained on www.mining.help. If you want to use Afterburner with multiple cards you need to use the AMD blockchain drivers and you are limited to 8 AMD cards. |

ethOS includes atiflash in their distro, so I imagine it is terminal based. Never tried using it though.

No problems for me with the new Bios v1.20. It's been running great more than a day.  |
