SD Boot fixed it for me.
As i understand the SD card must remain inside the rig forever..?
For now. Remo will contact you with experimental SD recovery to try to fix the emmc |

On the top cover of the SP20, or at least the one's I have seen, there is a set of carefully placed and threaded holes drilled. They don't just look like a fabrication "mistake". Does anyone know what those are for?
To secure SP10 type PSU |

another power cut - another non-responsive SP30
5 x SD recovery attempts
5 x 'xmas' alternating leds
0 x recovered
kinda sick of babysitting this thing - the SP20/SP20E didnt miss a beat, so wtf is wrong with the SP30.....again?!
It seems like a problem with the management board, maybe the emmc. If you're ok replacing it by your own, contact support@ |

SP20 bulk setup mini-HOWTOWhile setting up my SP20 mini-farm, I tried to figure a process to speed up the config steps usually required to perform over the Web-UI. The following might be useful for you if you need to configure a batch of SP20 devices with the same configuration. Please ignore if this has been posted already. Step 1: FW upgradeIf your units are freshly delivered, upgrade all to latest (mine was 2.6.1) Step 2: configure your reference unita) If you need non-standard cgminer configuration (e.g. API access from your monitoring server), ssh into unit and modify /etc/cgminer.conf.template to your needs. b) configure the reference unit; this scheme covers: root password, UI password, pool settings, HW settings c) start cgminer and ensure the unit is mining according to the desired configuration Step 3: grab reference config filesa) on your (Linux) PC, create a fresh directory and cd into it b) scp from your reference unit the following files - /etc/cgminer.conf
- /etc/cgminer.conf.template
- /etc/mg_custom_mode_sp20
- /etc/shadow
- /etc/ui.pwd
Step 4: bulk clone configsa) scp all files to your remaining units (root/root) Step 5: start the farma) open each unit in Web-UI (use the UI password set in step 2) b) start cgminer The process improvement is marginal for up to 5 units, but worth if you deal with 10+. It is also less error-prone and can serve as template for automated processing. Happy mining! Good and useful HOWTO |

Can't wait my 20s are scheduled to arrive today
how long did it take then? We're shipping within 24 hours of receiving payment. It usually takes 2-4 days. |

I think there's a range of Rockerbox ASIC quality (like GPUs) and the final efficiency also depends on which kind of chips went into that particular SP20.
Correct ( http://en.wikipedia.org/wiki/Process_corners) In addition, we skewed later batches to faster corners. Recent SP20s will be (usually) a bit more efficient. |

Did any try extreme undercloking.
If I am correct can get 0.5W/G in SP20 with 600W for a total 1.2 TH
Did any tested lower? Results?
Thanks in advance

Welcome to our thread Juan. Latest report I got from a customer (privately, by email): ..."The SP20 were slightly more time consuming  - anyway I ordered them only because I had some 1200W PSUs left which I didn't want to let unused. I figured that it should be possible to underclock the SP20 so that one 1200W PSU can feed two of them - which is what I got finally. Two SP20 connected to a 1.2kW gold PSU pull 1.07kW at the wall and generate ~2.15TH. Even better than 0.5J/GH at wall - very efficient and in every discipline superior to the only competitor S5."... The customer has experience with mining gears from all the vendors. He is mining since 2011. Guy |

Stange. Sometime, I don't understand the mods. |

Can anyone summarize what actually happened with Spondoolies' new chips and miners? I heard there may have been some problems recently?
Should be under mining speculation. Anyway, my reply is - patient my friend. Guy |

I think I will give SP a try. I been using bitmain as they have done me no wrong personally. But SP also appears to produce solid hardware. Not a fan of how involved they get in sponsoring surveys that favor them. But If the SP20e performs as I have been reading, then its worth at least a trial run in my environment (most of my monitoring is custom). The numbers don't lie when it comes to performance.
Let us put that survey / poll in perspective given what passes as fanboi promotion time and time again in these forums. We can give Spondoolies a thumbs up or thumbs down nothing more or less. In the 100s of user posts not one person has remained negative towards buying a Spondoolies product. I can't find one person that has had an issue with Spondoolies that hasn't been happy or at least satisfied with the resolution of the issue. For the most part the units are some of the best being offered. They ship on time and often to spec and if off spec refunds / reimbursements have been offered. I think the poll is a good gauge of CONSUMER feeling but you can read through all the threads, like I usually do, to find out why Spondoolies is the most trust fabricator currently. You don't need a poll to prove it. The forum has ample evidence to support that results of that poll. Unfortunately some people want to make more of stink about say Asicminer or Bitmain given their issues but to be honest those companies also try and do their best to rectify the mountain of problems they have. That is not the case of say Bitmine, Black Arrow, Minersource, Avalon, Technobit, BFL, KNC, HashFast, Cointerra and others. But if you read my guide you will see that. There is no real need to buy equipment for home mining or small mining operations you are fighting a losing cause. But if you are still painfully ignorant of the mining world or mine for fun or whatever reason besides a return on your investment then it is either Spondoolies or Bitmaintech right now. Edge goes to Spondoolies based on customers service and superior build quality. I don't need a multiple column framework using a ten point sliding scale to know that. Anyone in direct competition with Spondoolies also knows this and are scared. However Spondoolies can turn on a dime and pump out a million miners in a month can they? No they can't and that is where they are scared of their competition. We're not scared of the competition. You should be scared of competitors that can easily out produce you. Use whatever term you like. Cognizant, aware, respectful... I prefer the term scared. Puts the right point on it. Aware and respectful it is. Won't knock you guys, sure competitors could outproduce but often at the cost of quality, but they (SP) do have a solid engineering background and are making very solidly made hardware. I stayed away before because of price and other considerations that did not meet my immediate short term concerns. But SP is a solid player. They are now competing better in a way one should consider doing business with them. That does not mean Bitmain is bad. They are still IMO a great company, but it seems some people are having issues with them. That could be due to a number of things. Personally I am not having issues. But that is speaking for me alone. I have not had an experience with SP yet as far as hardware, so I am ready to take the plunge. SP can compete in other ways. The sheer quality of hardware alone is a selling point. If they build solid hardware and are diehard about any warranties they state, that already sets them apart. Customer service goes a long way too. If those areas are the ones they excel in, then there is indeed nothing to be concerned about. I mean really KnC? If that is one of their competitors then yea they got nothing to be scared about. Bitmain is about the only real competition IMO. Bitmain, BitFury, KNC, 21e6, AM and Sfards In that order. I can't go into details. Maybe I misplaced Sfards. Most probably there are additional unknown players. Most probably in China. Time will tell. Guy |

Yes, I asked Philip to run the poll. Yes, I asked the initial 5 questions. Additional 3 question were added by the community. This and donating 2 BTC to Wikimedia was my only involvement. Oh, and there was the untimely death of the first poll due to technicality error. Guy Having a marketing background prior to my IT background, I am of the opinion (which is just that) that it can be poor form. That said, you did donate to a cause of philip's choosing instead of paying him directly as he declined it. You are making an honest effort to work with the community and communicate with them. So kudos there. Your track record speaks for itself. I am not a particular fanboy of any product, I just prefer what works best and meets my needs best. Your hardware clearly demonstrates the chops for that. So again kudos. Overall I do think there needs to be more meaningful vendor related discussion, but the issue/concern is the vendors tainting results as has happened in the past. They can jump in and certainly defend themselves, but the OP needs to pose the questions/surveys on their own. Otherwise it just comes off as biased. While Dogie provides some excellent information, his vendor affiliation certainly can create a situation that shows bias. Well can't fault bick here he CLEARLY states this is biased and opinionated lol. My issue with poll results is...how do we know it was not gamed? Do we know who voted? We have no meaningful information as sock puppets are a common thing on these forums. It is easy to game the results. Lots of unanswered questions that can put this in a negative light unless its done in a way that shows it was done transparently. Thank you for your feedback. Guy |

^I think you are making a trivial issue into a major product fault that it isnt.
The Sp20 is already leading-edge for efficiency, and while theres a little space to improve efficiency with a little bit finer tuning processes, it might only be by 0.02-0.04w/GH
I think that you are wrong. I'm following this thread from the beginning and observed a very rapid release cycle with multiple regressions which is indicative of the developers thrashing around without understanding what is going on with the product in the field. I also noticed multiple user complaints about things like "entire ASIC loops disabled by BIST". I believe zvisha has already discovered a while back that GO/NO GO BIST that he had inherited from the Spondoolies' hardware designer is counterproductive and overly cautious. The use of BIST (in the field) should be completely abandoned now, it could be still valuable in the factory or in the pre-final-assembly stages. I don't know what is the internal personal dynamics of Spondoolies as a corporation. Does zvisha have enough inside clout to say NO! to some rather trivial support requests via Skype/ssh/Teamviewer? Can he influence the hardware designer to give him more information from the chip that just a single go/no-go bit and a temperature? What is required now is not more of "finer tuning". There's a need to step back and do some real research and appraisal of the entire field and how it is changing to more and more unattended operation. The cute "Thank you for the personal attention!" notices from the customers may be pleasant now, but they are actually indicative of the production problems in the factory. Thank you for your detailed feedback. I'll be happy to provide the internal documentation (Sitara - FPGA interface and ASIC interface) to anyone interested in trying to squeeze more out of RockerBox based products. The only conditions is signing mutual NDA. We won't be able to support such an effort, as our team is overstretched as it is. Guy |

I have found and examined the "SP20 Jackson Quick Start Guide". At the tail end of that 9 page document there is a reference to "SP20 Jackson User Guide" for further details. I have been unable to find the "SP20 User Guide" anywhere. Does this document exist, and if so where? Is the "SP3x User Guide" useful at all for the SP20? Sorry if this is an silly question, but I couldn't find anything relevant here.
We'll release the SP20 User Guide soon, Barbara is still working on it. We're very small team. |

Edit: What they said ^ I think the above was just Spondoolies-Tech's slightly unsubtly way of saying: Hey, our software is open source. Here's our git repository. Feel free to fork it, make changes - such as the suggested Nelder–Mead approach for N-dimensional optimization, and submit pull requests, and we'd be happy to review the changes and possible integrate them into our baseline - or you can provide your own custom builds for users who would be interested in it. Code repositories are generally not intended for end-users  I wish this was true. You can fork it and use it as you code the changes, but Zvi has limited time to review any pulls. I can still see that the UI on the latest SP 20 still have some errors which I tried to rectify since I got my SP30 .. forked the stuff, did the changes, which were never implemented by SP-T due to the lack of time .. The pull request is still there .. but I stopped asking, eventually in the end, the units are hashing .. Nevertheless, code repositories are good, and I'm an end-user. Probably the exception which confirms the rule. Correct.
 Checking. Please email Zvisha as well about it. Thanks |

in my opinion if you limit both max power (too low) AND max voltage, then the machine cannot optimize chip voltage properly and is run (at least sometime) sub-optimally.
You guys should pressure Zvisha and Spondoolies to implement a proper gradient-free multi-dimensional optimization method in their software: http://en.wikipedia.org/wiki/Nelder–Mead_method Do not reinvent the wheel! Is there anything more descriptive than a Git repository URL? When you go there, you are confronted with 8 "things" that I assume are kinda like directories. When you dive into them, there are bits of code and stuff. Wouldn't it make more sense to give folks guidance on how to achieve the desired goal using settings in the GUI? Am I just being too dense on this? The git URL was posted to allow 2112 to improve our firmware per her/his suggestion. |

Also, the SP20s initially had a problem with boards coming loose during shipping because they wasn't secured properly.

Correct. We refunded for the delay and RMA defective SP20. |
