Soo... this strange thing happened. In the midst of a block I get this:
20108 2013-09-19 13:33:14 2:12:55 128756841 3964 0.00000022 258846 26.12812726 24 confirmations left
Then the 6 blocks after I get none. All the while, my cockroaches are silently churning hashes. I restarted the nest and things appear to be working okay now.
Any ideas what would cause that?
you probably went on backup pool at the end of the block, and since slush is using score system the last shares of the block has more value than thge prev. for example if you are hashing 2 hours but missed the last 12minutes from that block - this would happen  How on earth would that happen? For all intents and purposes I missed out on 7 full blocks while I was away. No power outage. No ISP interuptions. It gave me not.  |

I've noticed that my home rig running six USB miners (roughly 2Ghash/s) and CGMiner will show a diff setting of 3 when I restart it after a crash. It will drop back down to diff 1 after a while.
My other rig pushing 25 USB miners is set for diff 4 (recommended setting via the drop-down setting on my worker setting page for 8 Ghash/s) and if I restart it then CGMiner shows the diff set at 8 initially. Again, it drops back down to diff 4 after awhile.
This is just what I've observed recently, I'm not complaining in any way.
As you may have seen by my previous post, I only have 7 running. The diff floats between 1 and 3. Typically it runs at 2 though. Things have been running smoothly for several days now and I'm not seeing any issues thus far. I have seen my HW error frequency change based on where I point my fan though. It's been fun learning how to get this all tuned up. I may invest in some more hardware once Capitol Hill gets a more intelligble stance on digital coinage outlined. Until then, it's very amusing to have a hobby that tries to pay for itself. |

USB miners always work at Diff 1, so I don't know why you're trying to change them...
I beg to differ there sir. While they start out at 1, mine auto adjust to 2. --------------------------------------------------------------------------------

So what you're saying then is that the 1/1 shares have value at the cost of devaluation of the higher rated shares?
I am not quite sure i get what you are saying, but probably: yes. If you submit 1-shares, you will submit more shares to the server, but they will give you less score. If you set the diff higher, you will submit less shares, but they will score higher. That way, your average score will always be the same. Higher diff means more variance but less network load. Okay, that is helpful to know. I'm still wrapping my head around all of this so I appreciate the responses. |

a Diff 65750061/1 share will find a block Pools distribute Diff1 shares historically to give miners something easier to work on and to count so miners can be paid - now that pools distribute variable difficulty shares (higher for faster miners) they usually convert back to diff1 for counting shares and paying miners https://en.bitcoin.it/wiki/DifficultyPools do not distribute shares. You find shares and send them to the pool. Difficulty does not effect how long it takes to calculate the hash, you dont get "something easier to work on", you just dont have to calculate that many hashes before one fits given diff. Your miners calculate hundreds of thousands of hashes per second. Those match a certain difficulty (and all lower ones). You choose a diff and send all hashes matching at least that diff as shares to the server. You tell the server which number is yours, and based on that the server can calculate your hashing power. If you set a higher diff in the pool config, your miners will do exactly what they did before, they will not calculate more or less or easier tasks or anything. Your mining client will just send less of your hashes to the pool, and they will be rated higher. The pool suggests a difficulty of 64 for ASICS running 60 - 120 GH/s. I would think that the difficulty could be set much higher than 64. Maybe the purpose is to submit many shares to smooth out the variance? I am not sure how this number is chosen. I noticed on one pool I set it very low by mistake and I hardly had any earnings. So what you're saying then is that the 1/1 shares have value at the cost of devaluation of the higher rated shares? |

Not a bad run so far...
Yeah! I want to go on record and blame this good luck on the DIFF. so keep that in mind when we have bad luck it cant be the diff. *apology* I am new to this whole thing and even though I've been trying to read as much as I can the last few weeks, it's a lot to absorb. Please forgive this possibly stupid question.*/apology* What is DIFF? It refers to difficulty, it an automatic thing which makes mining bitcoin more difficult the faster they are found, basically its to keep the bitcoin law true "coins can only be found once every 10 minutes (on average)". That the jist of it, I am also a newb so might have forgotten something :-) Thank you. How does it relate to the Diff 1/1 output? |

... to set up seperate workers for each device or to pool them together? Yes I am new to this. I apparently don't know the terms well enough to formulate this question into a search that yields results on these forums. Thanks! |

Once again, many thanks!! Still some fine tuning to do but it's working.

Thanks for the feedback! I have swapped out the USB hub and can already see a huge difference after only 5 minutes. Time will tell if this hub does the job.

Hi.  I've spent tens of hours pouring over forums, reading through hardware and software writeups and technical information. I can assure you that I have no illusions of getting rich from mining. I am more wanting to dabble. Learn how how the whole process works so that I can teach my children. I work in IT, having had some history as a field tech and desk side support before moving into Unix administration. So none of this is alien to me yet, it seems that getting to clear, unencumbered information about the finer points is the bigger challenge than mining coins. What I currently have in hand - - A desire to learn how to do this.
- an RPi: to which I have loaded Raspian and updated
- a powered USB hub
- some ASIC USB block eruptors: I think that the correct designation is Sapphire? I am finding that info on exactly what these are and who actually makes them seems rather vague. If you can help me clear that up I'd be thankful.
- cgminer
I have the system up and running sort of... here's my impediment and where I really could use some help/direction. Can I get some help translating this into layman readable form? I ran a single block erupter last night and after a few hours had the following... (5s):249.1M (avg):399.4Mh/s | A:1 R:0 HW:968 WU:3.5/m
