First, solo mining and pool concepts are incompatible.
Second, the number of shares you are looking at pool or miner? On the pool every hour there will be a different value even using one miner. And the average error is also not worth forgetting.
Appreciate the second look. By solo mining, I mean not dual mining. NOT mining on my own full node. The number of shares accepted is from the pool, averaging over at least 48 hours and also looking at 95% (remove top 2.5% and bottom 2.5% of values and calculate average) |

 SoloOnly mining ETH on nanopool Systems specs: Win 10 x64 64 GB ECC RAM Vega 64 + GTX 1080 Ti Each software was run on the same machine, using the same drivers for a few days. The overclocks on the cards were the same. I'm getting ~82 Mh/s and a healthy shares/hr is >70% of Mh/s which is 57.4 shares/hr. software all values 95% ethminer-0.12 56.16326531 56.0212766 claymore-10.4 55.64383562 55.64383562 claymore-10.5 56.41509434 56.41509434 claymore-10.3-nofee 59.62406015 59.62406015 phoenix-2.9e 55.67346939 55.5959596 The difference in shares/hour between claymore-10.3-nofee and claymore-10.5 is slightly over 5% This is not rigorously scientific but hopefully a helpful first attempt at discovering the most effective and efficient mining software and supporting developers properly. |

Appears they are not selling to well.
Were initially limit 1, now its limit 5.
Bitmain model is:
1) develop ASIC,
2) mine until hitting profit target
3) sell old miners to public
Repeat.
As one of the few ASIC mfgs still around it seems to be quite a successful model. They also made more rev/profit than NVIDIA this year and are buying up capacity from TSMC for manufacturing. As a company they are hitting all the right notes.
As for us miners, we basically get scraps after they've eaten the main course.
With the crypto craze seemingly over, all the casual day traders are leaving and the institutional investors are starting to enter. Volatility is decreasing and once we hit the bottom should be a gradual build up.

Here's a way better option IMO - buy one of these (Amazon Prime): http://[Suspicious link removed]/2EwdI7K buy a short C13 to C14 cable like this: http://[Suspicious link removed]/2BLaM4d Cut it in half, and wire it into the POW (super simple, I can take some pictures if people have any issues) - connect it to your WiFi, and voila! You not only have a more accurate sensor than the kill-a-watt, greater load (16a instead of 13a), you can calibrate it to a known load, and it has live JSON output so you could log it if you are so inclined. It's also tolerant from 90v to 250v, so you can run it on your normal household loads when you want, as well as the 240v ones. I use these things all over the place, I think they're the best bang for the buck you can spend - plus it's a relay, so you can remotely reboot them. Personally I reflash them with this firmware: https://github.com/arendst/Sonoff-TasmotaWhich makes them even better - although I've modified mine to be more miner-friendly. These look awesome! How do you wire this for 240V? The wiring diagram for the Sonoff shows L-N-G:  Household 240V has 2 lines on different phases and ground. $17 on amazon, $10 on their official site. Hilarious.
official site ships from China so 2+ weeks shipping time vs 1-2 days with prime $10.50 now + shipping SF E-Parcel $3.28 Registered Air Mail $4.52 DHL Express $18.98 |

thanks claymore! shows 44 Mh/s on Vega64 and 37 Mh/s on 1080 Ti, hopefully number of submitted shares shows a similar increase ethminer seems to run a bit faster on the 1080 Ti, any chance you could integrate those improvements? might be from cuda-9 code. Reported: | miner | vega 64 | 1080 ti | combined | | ethminer | 42 | 38 | 80 | | claymore | 44 | 37 | 81 |
Will report back on accepted share rate after 24 hours. ethminer gives me ~ 56.16 shares per hour claymore gives me ~ 55.64 shares per hour claymore reports a higher hash rate but im seeing less shares per hour, even with the 1% dev fee, theres something off. for now im switching back to ethminer. lol Set -dcri to 5 , 10 or 15 max even when solo mining  I'll give it a try if I get a chance.. using my own customized version of ethminer I'm at 83 Mh/s and ~ 59.2 shares per hour |

Thanks! Interesting AMD doesn't mention this on their own page. Sent a comment, hopefully it gets updated. |

I'm using AMD drivers Adrenalin Edition 17.12.2 (12/19/2017) and Vega 64 on Win 10 64-bit. I don't see a compute option as mentioned in the first post and here: http://support.amd.com/en-us/kb-articles/Pages/DH-024.aspxIs there something I need to do to enable this option or is it better to switch to the blockchain drivers? |

on some better news... here my first attempt on getting the Vega64 to work and get pass 2000h/s per GPU. Using the 1100HBM registry power table hack. Using the latest AMD Blockchain driver Around 270watts - Colorful B250 riserless 8 slots, M2-128GB, 8GB DDR4 RAM, Celeron G3930 LGA1151 CPU, WIN10 and 40GB virtual memory. Still need to get those watts lower - will need to finetune. "Geek Mark" was able to get his 6 x Vega64s at 1050watts Guide
RX Vega 64 (or flashed 56) Registry Editor, Power Play Table and Devcon Tutorial! https://www.youtube.com/watch?v=GlLxggLTFYE Awesome! following this as well. mind sharing where you got the Colorful B250 board from? |

I had the cut out the ends of the pci-e x 8 slots so the the pci-e x 16 cards could fit in the pci-e x 8 slots .. it works though!! damn thats a brilliant quick fix. how did you cut them and was it clean? |

I'll just leave this here:  |

Figured this out thanks to a few posts around the web and here.. 1. Clean install ubuntu-16.04.3-server 2. Install cuda-9 using these instructions: https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&target_distro=Ubuntu&target_version=1604&target_type=deblocal 3. Run sudo nvidia-xconfig -a --allow-empty-initial-configuration --cool-bits=28 --use-display-device="DFP-0" --connected-monitor="DFP-0" 4. Reboot 5. Commands for overclocking over SSH: sudo nvidia-smi -pm 1 # persistence mode sudo nvidia-smi -pl 150 # power limit Turn off LEDs sudo DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [gpu:0]/GPULogoBrightness=0 Core clock and memory transfer speed (mem clock?) sudo DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [gpu:0]/GPUGraphicsClockOffset[3]=-100 sudo DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [gpu:0]/GPUMemoryTransferRateOffset[3]=1900 Fans sudo DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [gpu:0]/GPUFanControlState=1 sudo DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [fan:0]/GPUTargetFanSpeed=45 |

Also, you should make a notice (red, bold letters) about the difference in the OC values between linux and windows, that's where things go wrong for the new miners, they see posted values for linux and apply them in afterburner on windows... core clock is same, memory is double on linux, eg. +1700 on linux equals +850 in afterburner on windows. Also, power limit in linux is in watts, in afterburner is percentage.
Woo thanks for this! eVGA 1080 Ti SC2 Win Core -100 Mem +950 PL 65% ethminer ~38 Mh/s ubuntu Core -100 Mem +1900 PL 150w ethminer ~38 Mh/s (ubuntu uses same settings, slightly less power for same hashrate!) |

Does anyone have instructions on how to do this over SSH?
