Yes, laptop repair is equally difficult as video-card repair and equally easy to RMA. ASUS X550 NL wih Nvidia 840M is in a 400$ price range with 2 years warranty. Why should I avoid mining with it, if I get fan replacement when it fails? Distribution of mining on more small miners is much better for cryptocurrencies and here existing GPUs, desktops, laptops are taking place.

What is the fee for DRK on multipool.us? Question was raised in another thread https://bitcointalk.org/index.php?topic=688510.0 about 20% masternode fee and multipool was not on list of "20% free" pools. 20% plus on DRK makes no point using X11 multipool. EDIT: Inserted link to mentioned thread |

The reason would be wear/tear. 24/7 laptop mining is not good on it no matter how you justify it.
And hat doe not bring in cooling/electricity vs amount earned.
You could say the very same for ANY KIND OF MINING HARDWARE. Should we all stop mining? Or one could spend 10$ per month on electricity collecting Curecoins, help finding cancer cure and in 5 years be surprised with CUR price.  |

Are you sure You want to solo mine BTC?  AFAIK that pool rewards You only if You find block. Why do You need such a "pool"?  |

What specs your laptop has? Especially what graphics card? I found that new laptops are very power efficient, quiet and therefore better for mining than desktops. My laptop with AMD 8850 hardly reaches 61-62 degrees mining and one with Nvidia 840M does not pass 64. Both can mine close to 1Mh/s with X11 algo. Yes, I agree that there is no point buying laptop for mining and expecting ROI, but when one already has it, why not mining with? Look around and read about mining software capable of mining X11, X15 or cryptonight coins, who knows, maybe You will mine thousands of coins that will jump in value thousands times over next couple of years.

I'm liking these little things but I keep getting problems with it. I start it up and it runs fine for a few minutes at almost 70k, then after a mere five to ten minutes I get this:
DM0: Comms error
Failed to open dualminer pn //./com158
DM0: comms error
DM 0 failure, disabling!
Thread 0 being disabled
I isolated one out of my five dualminers that was real troublemaker  . It was capable of messing all other (different) usb miners at the same PC under WIN showing usb and comm errors . Now, it is on his island (directly connected to the USB port of one server PC mining ok by himself  ) and the rest of dualminers are happy mining at 875 frequency together with Gridseeds ... |

Does anyone know what this error means/what causes it/whether to worry/and how to fix it?
Thanks.
CGWatcher should be able help You babysitting them. It's possible setting it in a way of restarting miner if sick/dead device occurs. |

First the payout are only based on daily shares so the averages out in 10 days are even more strange, there should not be ANY variations in these type of calculations. For fun I did a 12day calculation and it was still -12% off from what it should be. -12% for my are almost 3 GPU's not working and that are a lot of waste for noting.
I think that daily variations are maybe because of different time zones / times taken into account between pool and certified WUs. I didn't have enough information from data sources to make 11 days calculation, I could do only for 10. I believe Your math is shifted for one day, therefore difference arose. Also, during this 10 days, time for payment was shifted for 17 hours. That point could be also source for some difference. Anyhow, there is no 40-50% difference for sure. My opinion is that pool should have historical data and calculations for folders, so there will not be doubts about it. Like it is now, there is possibility for confusion and miscalculations. Edit: Edited percentages. |

My payout have been about -40% off and that is not a calculations error.
//Aboy68
I did calculations, and looks like there is difference on daily basis, but total is very close to what it should be. So please do total calculation of at least 10 days. |

Seems to be that I just received correction of wrong/smaller payment happened on 9-th of June. Keep up the good work... EDIT: My mistake, incom was from Minep.it, so no correction of low payment from 9-th of June... |

Any idea of estimated profit from the gpu folding. I don't mind helping but I need to at least break even.

1 7950 = 110k PPD = 3.67 Curecoins a day = $1.84/day = don't know what GPUs or profitability you have so I can't give you better numbers. This is ridicoulus. What am I doing wrong then? I am averaging 8 coins per day with 5 x R9 270, or this makes 1.6 coin per card!! I need more info than this - what numbers are you getting in PPD for each of those 270s. Between 50k and 60k. Rather 60k. 7950 > R9 270 I'm getting 88000 PPD for 2 x 7790 with 14.6 drivers. Don't think that You're off track. Thank you. 7950 makes 650 khs while r9 270 makes 475. This is a rough 50% difference so if you make 88K PPD this is OK. However, I am still thinking that both of us might off track, because someone else with 7950 stated he was making 110K PPD. That was probably me - my 7950 runs stably between 100k PPD and 120k PPD. It was at 130k PPD earlier but too many failed work units. However, keep in mind that the difference for scrypt mining won't be the same for folding because their are additional factors. If I could afford it I would get my hands on a 270 to do more testing but as of now 60 each is decent. Especially with 5 I would guess their are some heating issues that lead to some downclocking versus my 1 card. You could try going to the official folding forums to see if they have any advice. Well, it is still strange then as the other guy with 7950 is getting only 80K. Are you using an Intel CPU? Mine is AMD. I did not mention my 7950 but two 7790. Indeed my 7950 is stable at 91-96K PPD with 14.4 drivers and no overclock. Actually it is also rock stable at core on 975 MHz so I can't explain why I'm on factory 925. Maybe because of too many people asking what to do when stucked on 99,99%? |

Thx for the update, from the update logs I can see more changes made for dualminers and less for 5-chip gridseeds. I red all readme-files and tried --help with various parameters, but couldn't find syntaxes for parameters/commands specific for mentioned miners. Thank You in advance if such explanation/readme exists and can be pointed out or linked.

One question for anyone running Gridseed 300/350 units: I have 7 total but can never get the whole 7 online together. Always 3 or 5 or 4 or something always different, never all seven. Have checked units all are working individually. What is recommended conf file entry to see and load all seven GSD's?
Sounds like a hub/power issue? +1 (almost 100%) |

Does anybody have an example Conf for BFGminer to run in CGwatcher that shows how to setup for multiple Gridseeds using the ID of the gridseed and the frequency for it?
Thanks!
Unfortunatelly, CGWatcher doesn't validate bfgminer.conf with lists for gridseed's frequencies (even if You uncheck conf files validation), so the only way to define them is in "Mining profile"/"Miner Arguments" field. Actually You are copy/pasting Your command line there. Everything else in bfgminer.conf file is accepted (pools etc...). |

I also noticed that no lights came on on this device at any time, not when I plugged it into the computer, nor when I was attempting to mine with it... I know with Block Erupters, the green light lights up when you plug it into the computer so that you can see that it is working and that it is ready to start mining... What about DualMiner? If this device was working properly, should a light have come on when I plugged it into the computer? Or does the light on the DualMiner turn on only when it is mining and finds a share?
Is there any other software designed to work with this device that I can try mining with?
Is there any easy way I can figure out if this miner is working or not? If the miner was DOA, do I have any protection under Ebay policies?
Thanks!
You're on the right track with bfgminer. It should have permanent green led that darkens from time to time for a short moment during hashing. Sometimes it needs physical USB port unplug/plug to become live. What is Your line for starting bfgminer? Do You have it connected on powered USB-hub? If Yes try lowering working speed with --set dualminer:clock=800 or even lower (750) and see how it behaves. Units with Gridseed chips are worst quality hardware till now. 2 out of my 5 dualminers are behaving fuzzy. No wonder if You got bad miner. If You can't mine with it, try sending it back and requesting refund. EDIT: Small switch on dualminer is on L, not on B (or D), right? |

I don't understand. You have some devices listed as COM ports and on others you use serial numbers. Do you need to use both? or just one or the other? Also, how do get this to work with CGWatcher? It couldn't find my ASICs.
where can I find BFGminer PR3?
Yes, for dualminers (small 1-chip usb) You have no choice - You have to use path (COM port). For Gridseeds You can use path OR serial numbers. I prefere serial numbers for them. You can find download link on this page: https://bitcointalk.org/index.php?topic=248173.2560 |

This line should work: dualminer:all --scrypt --set-device gridseed:clock=850 --set-device dualminer:clock=850 --set-device gridseed@\\.\COM35:clock=1125 --set-device gridseed@\\.\COM36:clock=1125 Beware that mixing frequencies makes bfgminer not so reliable. |

I am just about at my wits end with these stupid gridseeds.
Nothing I do works properly. I am just about to throw these in the trash and try to find peace in my life.
The only software that seems to work for me is bfgminer.
I have tried cpuminer (works I think, but who knows)
cgminer with zadig drivers (can't even find the devices)
The raspberry pi that came with them (wouldn't even boot with the provided SD card, had to load a copy of scripta)
The pi will boot, but goes down after about 10 minutes.
So I am basically back to BFGminer. It's the only one I can get to work, if I modify the bat file that was included with my info.
So, here I am, back to bfgminer, I have modded 2 of 10 gridseeds, but I can't figure out how to run 8 of them at thr stock 850 and increase the clock of the 2 modded units.
When I add "--set-device gridseed@XX72117B5XXX:clock=950" nothing works at all, the command window opens then closes right away.
Yeah, Gridseed and Dualminers are PITA... You should put Your serial numbers instead. BFGminer versions are still experimental, BTW pr3 is more stable for me than clean-version. I'm using CGwatcher for running BFGminer because of crashing and unsuccessfull starts You are experiencing too. Here is my command line with my serial numbers and my serial ports, so You can't just copy/paste the line: bfgminer -S noauto -S dualminer:all -S gridseed:all --set-device dualminer@\\.\COM25:clock=800 --set-device dualminer@\\.\COM27:clock=850 --set-device dualminer@\\.\COM23:clock=850 --set-device gridseed@XXX2117B5355:clock=875 --set-device gridseed@XXXX4F8D5148:clock=900 --set-device gridseed@XXXX336B5148:clock=850 --set-device gridseed@XXXX5F7E5148:clock=925 I'm using also standard bfgminer.conf with pools definitions. |

|

Also, how do you get the serial number for each one?
Run first: to get serial numbers and paths of connected miners. |
