@chup : vega min fan speed is 2900 and with ambient 23 C Vega doesnt go above 63 C. I'm planning on water cooling it soon
@Geraldo : thanks! forgot i can hotlink now
Re: Power
Old:
110 V -> DPS-1200 -> Power GPUs and 12v EPS
-> 620W Bronze ATX --> 24 pin ATX + SATA
New:
110 V -> DPS-1200 -> Power GPUs and 12v EPS
|---> Pico PSU ---> 24 pin ATX + SATA
I will also sanity test :
110 V -> 620 W Bronze ATX --> GPUs + EPS + 24 pin ATX + SATA

I expected around 130 W CPU/system + 160 W Vega 64 + 140 W 1080 Ti ~ 430 W.
HWiNFO64 shows :
~ 25 W CPU
~ 178 W for Vega
~ 161 W 1080 ti
= ~364 W + motherboard + ram
so I'm running 100 W hot.
I'll run some sanity checks with the old power supply.

I feel like this is too much. I'm at 105W idle (Xeon + 64 GB ECC RAM, using this for other things when not mining). I recently upgraded drivers and swapped the power supply. Was at 480W before. NVIDIA 398.11 AMD Driver 18.5.2 Claymore 11.6 + ETHenlargement ~ 100 Mh/s OC Programs: MSI Afterburner 4.5.0 OverdriveNTool 0.2.6 OC Settings https://imgur.com/a/S4kxczSAny ideas on what I'm missing? One boot it showed 430W but then crashed after 15 min when I tried to login remotely. |

Awesome, thank you! Solves the problem I was having with OC settings reverting after a few hours.
Your OC settings are not supposed to be reverting after a few hours, no matter what software you use to apply them. The most likely reason this happens that I can think of is that your OC is not stable, the driver crashes and the clocks/voltages get reset to stock. Upgrading to the latest version of Afterburner ver 4.5.0 seems to have resolved the issue. |

Hello. As you know, MSI Afterburner allows us to save up to 5 presets. Last 2 days I was seraching how to swith presets automaticaly, because it is not convenient to me to set unsyncronised presets with undervolting curves on all rigs one by one for eath card.
Here is a way to activate one of your presets automaticaly, for example, before miner launch in batch file:
"<Full system path to Afterburner.exe>" -Profile<Profile number 1-5>
My example for the standard AB installation path:
"C:\Program Files (x86)\MSI Afterburner\MSIAfterburner.exe" -Profile1
MSI Afterburner has to be started at the execution time (as for me it starts at the system start), otherwise cmd window will not go batch next commands and you will have to change the command above launch with start cmd.exe /C
With this approach you can set an AB preset for ZEC when you launch ZEC bat file to start mining, a preset for ETH when you launch ETH mining etc.
One more benefit of usage such command line, that all unsyncronised presets with specified number activates in one time, unlike manual setting in UI.
You can thank me if you want:

Have a good day!
Damn this is even better since I don't have to switch to nvidia-inspector! Awesome, thank you! |

Use nvidia inspector, best way to do OC on windows and nvidia GPU's. example for a 6 gpu rig nvidiaInspector.exe -setBaseClockOffset:0,0,135 -setMemoryClockOffset:0,0,550 -setPowerTarget:0,60 -setTempTarget:0,0,85
nvidiaInspector.exe -setBaseClockOffset:1,0,135 -setMemoryClockOffset:1,0,550 -setPowerTarget:1,60 -setTempTarget:1,0,85
nvidiaInspector.exe -setBaseClockOffset:2,0,135 -setMemoryClockOffset:2,0,550 -setPowerTarget:2,60 -setTempTarget:2,0,85
nvidiaInspector.exe -setBaseClockOffset:3,0,135 -setMemoryClockOffset:3,0,550 -setPowerTarget:3,60 -setTempTarget:3,0,85
nvidiaInspector.exe -setBaseClockOffset:4,0,135 -setMemoryClockOffset:4,0,550 -setPowerTarget:4,60 -setTempTarget:4,0,85
nvidiaInspector.exe -setBaseClockOffset:5,0,135 -setMemoryClockOffset:5,0,550 -setPowerTarget:5,60 -setTempTarget:5,0,85 you can find it hereAwesome, thank you! Solves the problem I was having with OC settings reverting after a few hours. |

Kept the ETHlargement app running but the boost stops after a few hours - only way to fix it is to manually re-apply Afterburner OC - is there a way to keep the OC stable?
|

Was pretty skeptical but my 1080 Ti hit 56 Mh/s .. will continue to check if this translates to more shares/hr.
Thank you!

Not sure if folks have seen this: "DeepMind AI Reduces Google Data Centre Cooling Bill by 40% " https://deepmind.com/blog/deepmind-ai-reduces-google-data-centre-cooling-bill-40/They use machine learning over complex workloads however, I've seen miners do it with a basic three tier system: peak, off-peak, night-time. then its a matter of adjusting (preferably automatically) your overclock / voltage adjustment to your tier to maximize power efficiency based on power rates. |

Are most algos for nonce + hash generation formally proven to be completely random?
Is there a more effective method to generate nonce's rather than random brute force search?
Has anyone done any research on nonce / hash patterns?
Statistically speaking, there are fewer higher difficulty solutions so the probability of randomly 'landing' on one is low but if there's a way to guarantee any part of the hash, then it would drastically improve hashrate.
|

I don't see where the idea comes from that increased mining hashrate increases a coins' price.
A higher gold price causes increased interest in gold mining, not vice versa.
I believe the thinking is: faster hash rate = more coins = more profitability -> drives more miners -> more interest => more speculation on the coin There are some iffy transistions but that seems to be the 'pump dump' / penny-crypto way |

Interested as well. Have you visited the factory and see the production lines? Tested any samples?

Exactly how i check my power usage? is there a tool for that? because i don't have a adapter that displays the power usage.
it cost less than $10 from china. high quality, by pass the american middlemen. Can you share a link or model # or pics? There are quite a few but I'm concerned about electrical safety.. |

Yes, you are right in this statement, but I do not want to write a long story. It seems that Ethash is only algorithm that is not suitable for FPGA.
Not so fast, there is a guy who claimed he can do Ethash at 421.41 MH (FPGA Nallatech 385A). I am still waiting for proof, so it may be possible. Or I may be waiting for a very long time. https://github.com/Maetti79/OpenCL_FPGAhttps://github.com/Maetti79/ethminerThanks for the links. According to his latest results, the FPGA takes ETH hash from MEGA to GIGA. |

Awesome setup! Really cool to have the ability to drill down to see individual panel power generation and power usage of components.
How efficient are the panels?
Anything you'd change if you had to do it all over again but with the knowledge from this project?

Any of those 1080s the 11GB 1080 Ti's?
No sir Ah too bad. Thats a nice setup. Best of luck with the selling  |

ASIC <--> FPGA <--> General Purpose CPU / GPU
Trade off performance vs flexibility and development cost, unit cost and time to market.
Nice to see more public discussion about FPGAs, it is the next step in crypto/tech.
