Yes I am overvolting. The original resistor (05c value ~ 11k) was about .84 volt. I soldered 12.7 k (measured 12.4k), which is about .90 to .92 Volt. I have not measured the power consumption yet. Yes it allows me to set the chip to a higher frequency. Board 1 is hashing stable at a frequency of 1320 MHz, and after 10.5 hours shows only 10 HW errors. Board 0, which is at 1300 MHz shows 284 HW errors. I will try higher settings later  And when I measured power consumption I'll post the reading. |

 Board 0, is the original one, with HW error % of: (40*100)/(369+40)=9.78% Board 1, is the tweaked one, with HW error % of: (1*100)/(408+1)=0.24% Update: It is now 1.5 hours later and board 1 still has only 1 HW error, board 0 now has 75. Update 2: 8 hours later, board 1: 6 HW errors, board 0: 208 HW errors Pretty good difference   Temperature difference is significant though. |

 A2 board after I took the heat sink off. You can see the four voltage regulator circuits (two in the middle of the board on the sides, and two almost on the top of the board)  Dahmn those SMD risistors are small  I could not find SMD resistors of the right size or quantity below 100, so I took some high precision 'normal' ones of 12.7k (measured all around 12.36k) and soldered four on one of my two boards. Will post screen-shot to show improvement in hardware errors. Seems like there is a lot of improvement |

Looks like trouble with two of your blades.
Try hashing when disconnecting the four blades UA1 to UA4

The miner accepts the lower clock values, but somehow whatever options I add I end up with half mining speed on the pool.  Anyone any idea? [2015-01-20 21:49:02] Started cgminer 3.9.0

Hi emdje, is possible to run 2 session of cgminer in two detached console one for blade using the ssh connection?
Thanks in advance W_M
No it is not, the pi is connected to the control board which in turn is connected to the blades. As far as I know you can only control the control board. |

Emdje, any chance of an underclockers version?
I've undervolted my A2 and a few blades are already at 1000MHz but elec costs are now approaching revenue. I need lower frequency to get the voltage lower to extend its life a bit more. If you could add 50MHz or even 100MHz steps down to 700 or 800, that would be awesome
Mind sharing how you were able to lower voltage on the blades? Lowering the frequency does nothing to the voltage (does lower the strain on the chips, thus lowering the current), so I assume he soldered some resistors with lower values next to the voltage regulators. But to answer the first question. I will look at adding some more option on the lower end in the coming days. Will test it out and when it works I'll put it up. |

Valid points are being made here. Something indeed must be done about the stagnation in respects to mining. As said, a side chain is created to test out potential algorithms for a better difficulty adjustment. However, a blatant reduction of difficulty without adjustment of block reward would result in a to high coin production. This would result in a stable supply regardless of demand (the thought is that when demand goes down, mining goes down), which in turn would diminish the coins value. In order to control for demand in some way this test chain is set up and people are testing various things out. The basic idea is to stabilise the block time, whilst adjusting the block reward to control for demand. I don't know the details and technicalities but I do know they are working on it. First results are in, and what they tested now adjusted fine to the upwards side, but very slowly downwards, tweaking is on the way.
Hopefully I have not shared anything that is not true, but this is how I came to understand what is going on.

Ok - so what is recommended for my A2 Terminator 88Mh/s units?
I currently have the "InnoSilicon webGUI" software installed on them - which runs well and allows me to over clock to 1280 (or at least that is as far as I've gone) -- although I typically just keep them at 1200mhz.
Is there an image I can just copy onto the the builtin controller (I guess it is a Raspberry Pi) and it boots up with the new software / interface? Something that doesn't really need any special configuration.
I'd rather stay away from too many command lines -- as I don't want to make a typo and then they are unbootable.
Thanks for any direction on this -- or if it is even worth it?
Appreciate it!
If you want more overclock options (like values between 1200 and 1280, and above 1280) then you should go for version 3.0. This has extranonce support as well, providing more stable hashing at for example nicehash. You don't need to use command line stuff, just the webinterface will do. |

Apparently minereu has firmware that works with it: The MinerEU firmware has been updated and is also reporting how many cores and temperature of the cores now. please update
new miners will still have 6 module but each pcb panel will have 12 chips instead of 8 chips. which offer a total hash rate of 120M
Maybe you can send a pm to them. I search for a link to firmware for the 110MH terminator but could not find it. Thank you but my miners are 5 blades not 6 so I don't think they are the same. The one I have are LTC LIMITED--T SERIES. I don't know that version, and I unfortunately have no suggestions on which version you could use. You could try the one for the NEW Mini terminator, but it is not stable (but coded for more chips per board). If that does not work you can try the newest version 3.0. But no guarantees it will work (it will NOT damage the miners though). |

So I'm alittle embarrassed to say this -- but what does "Extranonce support" give you?
I have some A2 Terminators 88Mh/s. Does this new image provide more efficient hashing with any pool? Or just certain pools that support this feature?
What are the benefits? Is this something that would work with my miners?
If there is an easy to read thread about this then feel free to point me in that direction.
Thanks!
It makes for example the change between jobs on Nice/Westhash go a lot faster, without the reconnects. I don't know the deep technicalities. emdje
in your opinion is simple to reconfigure your image to use the web interface to comand gridseed blades?
if i use your image and change the cgminer with a cgminer for gridseed its work?
i know you develop for innosilicon but i have 2 gridseed blades and web interface of a2 is the best to use.
Gridseed is very different from A2, for example the setting of the clock frequency will not be the same. If you want to try, you would need to adapt the index.php as well (the webinterface), because the command that is send to cgminer is send from there, and that command must obviously be different than that from the A2. And there is another copy of cg miner in /usr/local/bin Might be better to use Minera for your purpose: http://getminera.com/ |

hy emdje i'm using your "Overclock version 2.0 by Emdje" to mine on 24 different pools at the same time with load-balance activated and work well.
do you know how to activate the extranonce?
i use --load-balance, is there a command like --extranonce or similar working?
thanks for all
i have an a2 mini 8chips 2 blades.
is the 3.0 ok if i use it?
Glad to hear it works well. The version with extranonce subscription is version 3.0. I implemented this code: https://bitcointalk.org/index.php?topic=850620.0 You enable the subscribe extranonce function by adding #xnsub to pool url's tail. In the case of nicehash this is: stratum+tcp://stratum.nicehash.com:3333#xnsub |

GUYS - is this tweaked version compatable with the newest 110mhash A2 Terminator? The earlier versions were not...
Sadly it is not. |

emdje, try run it with nohup
I did, still the same. |

Bensam123, in the Crypto world you have to be a skeptic or you will lose all your money. I am perfectly fine with you losing all your money, but you are currently being a "disinfo agent". I believe you lack critical thinking skills. You assume MRR is accurate. It is not. MRR is acting as a trusted third party to deliver you information regarding hashrate. In reality, they only know about hashrate as much as the user pool knows about it. If the pool is fake, the hashrate is fake. That is all. You assume that x11 hashrate (all x11 coins added together) is big enough to support 170 extra gigahashes. It isn't. Total network hashrate of every single x11 coin is ~= 100gh. Please see this evidence and draw your own conclusion: [12:46] Heliox: Wolf`, that bensam guy is so convinced that it's real, show him the mrr page again,
it's rented right now, from the moment that one rig got rented, the hashrate dropped to 0 :)
[12:47] Heliox: https://www.miningrigrentals.com/rigs/13743/
[12:47] Heliox: :)
[12:59] kotarius: djm34 has the best theor
[1:00] kotarius: fake hash rate simulated by his a pool he created
[1:00] kotarius: i mean of course...
[1:00] kotarius: thats the only explanation
[1:01] kotarius: because he is demonstrating 170gh, market hashrate didnt change.
it should have gone from 100gh -> 270gh, but it didnt
[1:01] kotarius: and all x11 shitcoins would have died immediately hashrate drop to 0 can be seen here: https://www.miningrigrentals.com/rigs/13743/ |

I am trying to find what it is that effects this half hashrate problem. Version 4.7.0 has the same problem, and I have not been able to find the problem there (starting with nohup did not help btw) I honestly have no idea how long that will take. Also, I have a lot of things to do this week and only limited time to spend on this. I did manage to crank the SPI speed from 4MHz to 8 MHz, that might improve hashrate stability.
For now I think you are best of in flashing the most recent version with extranonce support.
I think the new cgminer does not start upon boot because it anticipates an internet connection. It is important to try to start it after network interfaces have started. Put this line: post-up /etc/network/if-up.d/start_sgminer.sh as last line of file /etc/network/interfaces Then: echo "#!/bin/sh" > /etc/network/if-up.d/start_sgminer.sh chmod 777 /etc/network/if-up.d/start_sgminer.sh and put all start usual start scripts under #!/bin/sh in /etc/network/if-up.d/start_sgminer.sh IMPORTANT: USE FULL PATH TO SCRIPTS AND FILES EVERYWHERE IN STARTUP SCRIPT Thnx for helping. But the problem is that it does not start trought the webinterface when it is booted up as well. And then the network interfaces have started allready. It only works when started throught the terminal, and than it only reports half hashrate  Somehow the terminal executes a little different than the scrypt. |

Hashrate of cpu is slow, so shares are not submitted in a constant rate. Sometimes you find a share short after one and other, so hashrate is 'high', sometimes it takes a little longer to find a share with a low hashrate, resulting in a lower number.
