You have all the sleep/hibernate settings turned off in windows? You should be able to look through the windows system event logs to see if the OS is the culprit. This was caught me once or twice.
Yup. If it's every 6 hours, it won't be the bios. Check hibernation settings and: powercfg /h off |

Is their any resource that explains the main contributing factors to the difficulty of a given coin? My impression as a newbie to all of this is that it is either solely or mostly driven by the volume of miners pointed at a given coin. For example... price of XMR goes through the roof, everybody and their brother switch their rings to mine XMR in the last 2 days and bam! difficulty rises 20% in that time period. Similar thing when ZEC came out and most people started mining it... both XMR & ETH difficulty bottomed out. Is this the only main driving factor or are their other things to consider?
Well.. That is one factor and the last factor is reward. Every X amount of months / years, the reward halves. As Hotmetal stated, the overall network hashrate is adjusted every period [variable per coin] to ON AVERAGE yield the same amount of coins. If the network hashrate increases by 20% because everyone's brother switches over, you can expect ON AVERAGE that your payout is going to decrease by 20%. Each pool will have a "local" average on top of the network average. I think this (variance from expected payout) is much more pronounced with coins that have a longer block time (a.k.a. bitcoin [10 minutes!]). With coins with a very short block time (a.k.a. ETH [15 seconds!]) the variance is naturally much less. I hope I explained this well enough. Switching programs do have a downside if everyone uses one all edges are lost. and they can cool off a hot coin. I recommend 30 to 60% on a switcher and 70 to 40% on your hope for a hot coin. I also plug zec as the market cap is tiny well under 25 million when I last looked. I could pump the coin and thats saying a lot as I sure as fuck am not spending 100,000k on a pump,but no coin has this tiny market cap except for zec. I've figured out a pretty novel way of doing predictions (without using difficulty or market value) which could prove extremely profitable if you're mining and holding a coin for up 4 weeks (worst case). However there are other things to finish up before diving into that. I've done most of the most profitable auto-switching code server side already .. Now to start working on server API and Linux / Windows side code. |

This causes network difficulty swings to have exaggerated effects on the profitability model.
I'm not sure using network difficulty is a good way to predict things. Need some suggestions. |
|

my thought was: because profitability is modified by price and difficulty, depending on your strategy you may want to mine what is easy to mine to hold as much coin as you can.
Sometimes price goes down, but depending on your own feeling you can expect a better price soon. In that case, it's better to continue mining even if calculator say it's not good because of the actual price.
For example Phil think ZEC will grow, so he can't compare easily profitability for zec through the usual calculators.
Same for me with Eth, I think it will grow again.
I don't know if many people would be interested by such features. For me , the 4-5 main Alts vould be enough. Of course it's not a life or death question.
In the good old bitcoin wisdom calculator you can change all data, including BTC price and it is someimes interesting too for projections.
I think you're maybe trying to solve a problem that doesn't exist. If you "believe" in a certain coin for the future, that is fine and you should stick to it. If you want the same balance of each alt, that too is easily done and you don't need a calculator for that. However .... I'm already giving you the most profitable coin (factoring lots of inputs that all the calculators do not factor in). If you're after a prediction for the future most profitable, that is something I could try to do separately like this:  This causes network difficulty swings to have exaggerated effects on the profitability model. |

Do you guys know a way to put your own coins price in mining calculator (such as coinwarz or whattomine) ?
When you have a "hold" strategy, and expect a coin to rise, mining profitability would be more accurate for you if you can calculate it with the expected price instead the actual one.
But I don't know if this is possible ?
@hotmetal : maybe it's an idea for you ?
https://badmofo.github.io/ethereum-mining-calculator/Hand adjust your hash rate until you have your current balance and then change the pricing. It is something i can code but what would the point be? How granular would you actually want it? Just 1 coin? There's a lot to consider. |

After the ROM mod, trying to attempt any finetuning in AB 4.2 or 4.3 will crash the rig or become unstable.
For 480 case, messing with wattman is no picnic too and I could only get 33% reduction in -mV.
But using the ROM mod as it is, can already achieve 29MHs, low power - just under 1000w for 6xGPUs and considerably less heat.
Without using his low-power rom and using a different one, I have a 6 card rx480 rig doing > 29.1MH/s for each card pulling total 882w at the wall. That is using Windows and the rom and applying -100 mV drop and it's rock solid (also Biostar motherboard). That adds a lot of savings when you have multiple rigs! the current SM Linux @ 6x480 @ 730watts with Heliox rom is running well and integrated with Claymore Ethman monitoring so I am happy with that. I probably consider your approach too (Boysie's rom?) further power savings but my intention is to move away from Windows as much as possible. No plans to dismantle this rig since its already ROIed -- but all future build will default to the 4GPU build. What is SM Linux? Not using Boysie's, using Jukebox's bios. I would *love* to use Linux (it's what i'm most comfortable with) but the power saving from using Windows means at this point I don't have much choice unless I can somehow figure out how to do -100 mV drop for each GPU. |

Explain that it is unrealistic BTC fees, you are charged from each participant in the rules there is no mention about this mess !!!
BTC fees should be paid by the pool like all other pools are doing. Not only is nicehash taking their 3%, but they also pass on the BTC network fee onto you so even less profit! for payouts to miners/sellers are PAID by us (NiceHash). And yes, indeed these are significant amounts of Bitcoins for transaction fees because there is constant blockchain congestion (full Bitcoin blocks) - but once again, all these fees are covered by us and are NOT deducted from payments to you. So these are our extra costs, but we are covering them all. And we are including large transaction fees for YOU to get the Bitcoins as soon as possible - so that sent transactions are confirmed as soon as possible. That is great news.. Why list it there though? That creates some confusion. |

Hope everyone is making money on XMR -- all my 33 rigs are on Dwarfpool XMR.
Yup, XMR all the way. My long term goal is move to all Linux for stability and further power savings (6x480 takes 1000watts on Windows, but only 730watts on Linux)
Please explain how you managed to save power using Linux when you can not do -mV drop. the RX480s were originally mining ETH during ETH hey days All my 65 x RX480s are modded with "29MH480LowEnergyOK.rom" from Heliox/Eliovp Used the same cards on ZEC and XMR, in addition to ETH with no issues and still achieve good wattage. Settings on Linux is at "stock" no settings in simplemining or ethOS. Under windows you can lower power consumption considerably with Trixx or Afterburner. I'm trying to gauge how you come to the conclusion that Linux uses less power than Windows. |

1200 is too small for 6 rx480.
Overclocking or even leaving it standard isn't very efficient (hash per watt). You want to undervolt and underclock and it will be using ~120w per card (including system components). |

SGMiner-GM, AMDGPU-PRO, Sapphire Nitro+ 470 4GB (Hynix), custom memory timings.
You also might want to mention the chance of him achieving those figures himself is close to zero  That's true. then whats the trick behind this lol? to achieve your hashrates. Might be because you are using linux? I told you already - custom memory timings. Not copied. I think it must be 1500 memory strap copied in other higher timings right? is that all the changes you made? No. It's custom! |

AriesIV10 , Please tell me, did you do something with BIOS on your card, or they work in defaul mode?
  I have MSI RX 470 Gaming X GPUs on this RIG. Here are the Stats on each gpu: RIG001 MSI RX 470 gpu01 80.5% Hynix RIG001 MSI RX 470 gpu02 79.8% Hynix RIG001 MSI RX 470 gpu03 73.1% Hynix RIG001 MSI RX 470 gpu04 65.0% Hynix RIG001 MSI RX 470 gpu05 64.9% Hynix RIG001 MSI RX 470 gpu06 73.7% Hynix Here is what I did. 1) Strapped: Took the 1500 and copied to the three settings larger than 1500. Watch this video that shows you how to strap. I did the same method: https://youtu.be/OP_zSP2H6ho This will get you 23.5mhs per gpu 2) On the MSI Afterburner I set the Memory Clock to 2000 and the Core Clock to 1150 and press the check(Apply). This should get you the 28mhs. 3) Now I go to WattTool and look at the numbers for each gpu individually. In this case for gpu "0:Radeon (TM) RX 470 Graphics" look at the mV number in "R7" = 1150mV. I do not want this number less than 1000mV. This is just my preference. Look at the Voltage Offset. Whatever number you put in here it will be multiplied x 6.25 so, 20 x 6.25 = 125. 1150 - 125 = 1025mV(which is above 1000) so this one would be -20 and then click "Set" This gpu should now produce much lower watts. 4) Go to the next gpu and evaluate the number and make the changes in the Voltage Offset based upon the mV number in "R7." Each gpu will be different. Good Luck Let me know if you have more questions. Is there any way to not have to run wattTool every time? I see you can hand adjust the voltage for each phase - is there any way to set that in the rom automatically using some tool? (Polaris Bios Editor won't do it across all phases) |

yes but this rig was first for testing purposes and I left it mining ETH while all my other rigs are on ZEC
You mining and holding or mining and selling? |

What it looks like to me is a couple butthurt devs pissed that claymore getting all the action. When it comes to people and their money well seems nowadays anything goes. What purpose would they have blatantly talking about ripping him off right in his own thread. Has to be to hope claymore gets pissed and stops developing so we have to use their crap software??! That's a new low if you ask me. Instead of taking the time to rip claymore off. Why don't you guys go back to school and learn to code. Then you can come back with better miner and charge a fee  They are pretty good at coding, trust me and their knowledge typically goes a lot deeper than even the more typical coder. I think it wasn't meant to be malicious but was taken / done in bad taste verses sending him a message personally (off-list) to state they think he has a good sense of humor and how they defeated it. |

Thanks, I'll switch to Zcash than
Or you can switch to ETC or EXP. Probably considerably safer to choose ETC as it's value typically mirrors ETH almost minute by minute. |
