its an End of August sp30 machine not sure if it is still under warranty what is the procedure for replacing it ? Is it via email or via
the website.
thanks

It's looking more certain that what we've been seeing in our DC is a poor reaction of SP30s to temperatures below about 6°C. We haven't seen any issues with SP10s yet at these temperatures.
Some machines work fine at low temperatures. I've seen a few operate just dandy at intake temperatures as low as 2°C. However, others will show problems at intake temperatures as high as 8°C. When a machine has trouble at low temperatures, it's often specific ASICs that show the problem (often #2 and #17). It's not always the ASICs in the front that have issues, though it seems more common to be those. Once an ASIC has trouble at low temperatures, it sometimes has trouble even when warmed up. Sometimes it has to be disabled permanently; other times it can be enabled once the machine is warmer. Indeed, but a hardware to be reliable, must handle 25°C variation without too much trouble.Here at low temperature some ASICs can't start. It will be a good idea to add a 'delay' option for the troublesome ASICs where they are turn off during the cold start and enabled later. Adding an option to change the Fan speed according to the intake temperature, will be a good too idea too. (I suspect this issue to trigger some machines crashes when minergate restart). We're investigating. I see the same issues at higher temps : 24c to 30c , I disabled the troubled asics and still every few hours when I check the machines half the Asics will report failed , sometimes all with the machine not even mining at all. Its a deeper issue with the firmware than just temps I think. Getting really frustrating at this point basically tried everything to keep it stable but nothing seems to work. I have to bounce it every few hours but I don't have time to babysit it I have other stuff to do. |

confused a bit on the stat pages for the sp20 vs sp30 using 2.5.13
Statistics
Name GH/s 5 min GH/s Accepted shares Rejected shares Errors Utility Last Share
sp20 1626.025 1765.03359 1197 0 0 45.78 08:42:25
as you can see the mining rate is stable at 1626 GH whereas the 5min gh/s stays from 1700 to somtmes 1800 GH
same thing on the SP30 the 5 min rate is conistantly higer sometimes I see like 4700 GH vs the actual of 4400.
which number is the real number ?

Version 2.5.12 became the official, 2.5.6 removed and 2.5.13 is the latest experimental.
2.5.12 - different handling of BIST and Murata flow - improves stability.
2.5.13 - sets default (after factory reset) values to 1275/288 in SP3x/SP2x. Redirection bug fixed. Handling of ambient temperatures lower then 0c added.
So which firmware should I install on an Emerson PSU set I currently have 2.5.1 and its still unstable not getting more than 3TH and asics keep failing with that loop error. I rue the day I updated my firmware when I was happily hashing at around 4.5 TH for months. Is there a process to roll back? you can roll back contact Zivi there is a URL where you can download the firmware directly i.e the version you want , in my case I thnk it was too late some of my asics are permenatly damaged I think. Is there any possibility of those with damage hardware to get coupons for discounts on the newley priced sp20s ? I'm down around 250GH of hashing power now |

I got nothing either I paid the full $1200 price for an sp30 (using my $800) coupon from a my sp30 august order that was not up to specs . I would have put together the BTC to buy 2 sp20s at this discount price so sad  |

Still having issues with mine. I'm thing 2.5.7 might have damaged my Asics its super unstable. Right now I have it reset to factory setting at 70% fan. When I try to bump up the fan to my normal
80% the problems get worse : constant cgminer restarts asics going into fault loop. ugh this is not good.

We found out that dropping the SP20 package may cause the boards to shift.
We got complaints from about 2% of non palletes customers. Most of the units can be fixed at home by replacing the boards.
We halt individual package shipments for one week, until we'll solve the issue.
If you got such SP20, contact support@ for miner assembly guide. If the SP20 was actually damaged, we'll RMA.

Hi. I got my miner November 7th. Got it all plugged in and the 2nd board would cause a halt in cgminer. Miner would not hash. Eventually, I disabled all the ASICS on the 2nd board, and the miner would hash with only the first module. Noticed that the boards sat at an angle inside the case, so I opened it up and re-aligned. The boards are not screwed in or secured with anything except some grooves raised up from the enclosure. Pretty cheap design, which is prone to board shifting if handled rough in transit. After re-aligning, I manually enabled and disabled each ASIC on board 2, and figured out that ASIC 4 will not work under any voltage, the other ASICs on the board work fine. Getting 1300 GH/s with 7 ASICS...so not too bad at max 225w per module setting. I'll turn up the juice once all the problems have been worked out, hopefully. Got an e-mail tonight from Barbara saying they will refund 0.12 BTC because the SP20s shipped late. I'm cool with that, so I thanked her and also told her to forward my diagnosis to tech support. Also filed a form for tech support asking for directions as to how to proceed. Requested they send me a replacement board. I'd rather not ship the whole thing back and lose hashing time. I can do major surgery on just about any electronic device without a problem. I have an SP10 Dawson also that has been going without a problem for months now. I can't really say I'm impressed with the SP20, because I'm so far pretty underwhelmed. Firmware is still 2.5.6, not really sure about any other versions. Hopefully they will get all the bugs worked out soon. Yup, I'm facing the exact same issue as you with the warped board. Barbara has also replied to my earlier email which included pictures of the board when I unpacked it saying that they are looking into it. Let's hope they are able to get back with a fix. Cheers We'll ship replacement SP20 after fixing the package issue next week. Guy heh ....get replacement miner ..grab both miners move quick! (kidding just kidding) Jeez you are an idiot |

This is Spondoolies-Tech thread not price comparative thread.
Server grade is server grade! I got 7 s1 in my house and i don't cry!
Go buy more knc, hope you burn all your 6pins conections!!!
The SP3+ units are great so far from my experience the sp20s are underwhelming and I thnink that is what he is talking about. From my tests the issue seems to be somewhat power related. I think the SP20 would have been a better machine with an included PSU that could handle those chips. The sp20 has already fried one of my PSUs ( a 1200Watt corsair) right now I am using and 800Watt and a 1000 watt unit which should be plenty of overhead. Sad thing is these chips are quite powerfull. when I set the voltages to .79 (max) I'm getting 1.78 TH at 1200 watts but its far too unstable. this is my most stable settings 1652.08Ghs at 1190 Watts Temp Front / Back T,B 27 °C / 78,76 °C Fan Speed90 Start Voltage 0.78 / 0.75 / 0.77 / 0.75 Max Voltage0.79 Max Watts288 / 288 / 288 / 288

Does anyone else see problem with 2.5.7?
I had one unit that had the same problem as jtoomim, but restart got the chip back up. I am downgrading to 2.5.6 right now. I rolled back to 2.5.6 with Ziv's help yesterday but I am still getting that error : 17: disabled (bist cant start, stuck X) hope my Asics did not get damaged or something Maybe the code needs to be tweaked to restart those stuck asics or something after a while since it seems if I restart minergate or cgminer the dead asic comes back for a while. What worries me most though its the same Asic that fails all the time , sometimes 13 will fail as well. |

cant see any of the pics except for the top two but yup that's the same issue I had |
|

Anybody with a SP31 found a 'sweet spot', can't get more than 4.7THs out of mine.
Anyone with SP31 getting more than 4.7Th/s? are you on 240 V ? what are your temps like. Even the SP30 looses close to 200TH it seems per 10deg temp rise |

I had the same problem with one of mine as well and after disassembly, I found a chunk had been taken out of one of the VRMs. I'll post pic's as well. ouch ! I was a bit luckier , no actual damage to the boards despite the cracked corner. The SP20 is a cute and sexy little machine but it definitly not worth $1300 (with shipping) Best hash rate I think at 110V (assuming you have great cooling) Looks like maybe 1.8 TH max at close to 300 watts per power slot. right now at 24c front and 79c and 80c back it hashes around 1650 TH max while pulling over 1200 watts (it actually spiked at one point and blew out my power meeter and maybe one of my PSU's , good thing i have spares) maybe it does a bit more at 240V i have some ic14 to ic13 cables comming early next week and ill try them on a dedicated PDU and see what happens |

Good Job stan!!
Marv you probly should contact zvi via skype - everything i said came from he and hes got most of not all the answers.
Best Of luck bud & at least its doing something - better than DOA is a small bonus.
Ok looks like I got the issue figured :" The SP20 does not like that Ad2p adapter to combine two PSU's it seems. I ran both PSU's (1000w and 800W) separately and I am getting close to the advertised 1.68 T or so what I am finding is these rockerbox chips can run at up to 1020HZ vs the cap on the sp30 chips of around 850hz Im using an add2psu with 2 cougar 700s. getting 1.55 , but havent tried increasing Hz I can also verify rats have gnawed through ether cables, telephone/net cables, window frames and mosquito netting - i had never experienced rats before living in asia - theyre fucked! as are the weird feral cats!! Hmm do you have any pics of your ADD2psu setup ? not sure why mine is not working. You did have the short the pins on one of the PSU's right ? regarding the HZ , what i meant Is I raised the voltages to around .73-75 for the two top cores (since they seem to run cooler) |

Well doh
my SP30 got upgraded to 2.5.7 which seems incompatible with the orginal sp30 units
seems to have bricked the unit it will not connect to any pools. I tried rolling back the firmware buy using the dropdown to do the manual seclection
but nothing shows in the dropdown.
what next ?
You can tell your support is too good when people assume they will get it by asking rhetorical questions in public forums. I was actually asking for help from other members not from support that's always my last resourt |

@edgar did that they wont use over 200w it seems so im capped at around 1380 TH @ 800 or so total watts
even upped voltages and stuff to max but no dice I can't get any where near the advertised 1.5TH
temps are fine around 55c

Well looks like I have a unite with broken Asics guess I should have took cash compensation. What is the RMA process anyways NM color me a technican I somehow got it working gona seal this back up and see how it hashes. ** I played around in the asic setting area on the admin page btw : disabled all then enabled again , don't know if that did it tho *** Uptime:73 | FPGA ver:100
