I spoke to soon  12 hours in and the blade is half down (-'s and x's) and the S2 is hasing at around 930 GH/s. Still, thanks for all sharing your knowledge/trials with the S2 guys. One blade may be RMA'd. I'm pleased to say that Bitmain got straight back to me when i requested RMA information/advice on steps to take... Investigating further.. I ended up RMA'ing that card they asked my to "press on all the chips", too. The RMA process for me in the US is at least pretty painless. Good luck! |

Yes but upgrade of S2 and new machine are two diff things .. I want buy new machine and not to DIY .. thats why I hope in a brand new S4
I'm not sure they would, in fact, be different. The S2 upgrade cards would likely just be the same card they would ship in the S4. You've already designed a chassis in the S2 that makes upgrading easy, so why redesign that wheel? |

@ BITMAIN
what about S4 ( someting based on S3) ?
Like 4 or 5 THs in box like S2?
The upgrade cards for the S2 are being engineered, and I imagine that will usher in an S4 unit with said cards. With lower power consumption, they should be able to create a more dense product with the same PSU, more or less. That's all conjecture on my part, minus the bit where they stated they are working on S2 upgrade cards, which is in the OP. 1. Will there be upgrade parts for S1 and S2?
Yes, there will be. But we still need to solve some production/testing problem before we finalize the plan and public it. |

i got alot of discarded. is it normal?

Yes, the S2 manages to create a high amount of discarded shares. edit: I could have swore I stumbled across a calculator that included discard calculations, but can't seem to find it just yet... |

Woke up to a dead S2 this morning. Like a previous poster, I have moved it around to different outlets, nothing. I noticed the power bar that it was plugged into was melted slightly melted in the outlet it was plugged into. I did plug it directly into the wall to see if it was the outlet, nothing. How do you know if the PSU is bad or gone? This is not good.
Fixed it. Removed all of the blades and reinserted them. I would still be concerned about the slight melted outlet on your power strip. Make sure you use a heavy gauge power cable out of the back of the PSU to make sure it doesn't overheat, same for the power strip. I'm going to check into that also. They sent a 200V power cord with it. I did use a heavy duty power cord 120v. I'm trying not get a mini data center in my home. I'm looking for another power strip in the meantime. Any recommendations? I've been using an APC branded power strip (not a UPS) on my test bench for extended runs and it never warms up. The one I have is model P7T and has a 14 AWG power cable feeding it. http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=P7TIANAEE, however, so others should feel free to chime in! I am using a 14 AWG. I'll look into this one and see. Let us know what you decide! |

How do the Antminer S3s perform on p2pool?
Batch 1 ships July 10th, I'll slap one up on receipt of goods. |

It's time for you to stop thread jacking! This time it's worth your reputation!! |

How loud is the bank of Deltas?
They sound like a jet getting ready to take off:) They are UHE spec, about 102 CFM at 7500 rpm, 62 dBa I figured they would, but this setup is perfect for the DC environment, either way. I'll hit you up later today when I get a bit more time. |

Nice! The front plate looks pretty thin, will it carry the full weight of a loaded case?
This is a prototype, so the answer is no. It's only 0.794 mm thick. I'd beef it up or use a fixed shelf rails. This is an amazing design, thanks for sharing. How loud is the bank of Deltas? |

Other solution :Remove the bad board Overclock the S2 Run the Overclocked S2 with only 9 boards I will have the same hashing speed as 10 boards  What frequency are you running? I facepalmed myself just now for not thinking of this! option 'freq_value' '0801' #212.5M option 'chip_freq' '212.5' option 'timeout' '40' Cheers for that--I'll give that a go when I get a chance this week. I'll let you know how it turns out. |

@ Bitmain
I'm ready to buy upgrade boards for my S2's
Second that, although they stated earlier (in this thread, IIRC) that they needed additional engineering for that product. It's in the works. |

Just got a paid confirmed on a payment with only two transactions. Looks like they're confirming manually or it's set to a low threshold.
Same here. 'Paid' after three confirmations, maybe two. I am sitting at 2 confirmations and still showing unpaid on the website. This is normal for first day orders with BM, it should clear just fine. Let us know how it turns out! |

i had see someone to tell to put in and put out the sd card
untill the board start again boot
but i do not remebe very well the steps any details
please
After having no setup issues and running great for the last couple of weeks, I woke up this morning to find my batch 1 AntMiner S2 not hashing, fans going full speed, panel dim and the red light solid. Recalling that others here have had the same issue, I went back and skimmed over the previous posts and found that the likely issue was probably a corrupt SD card. That was indeed the case, as I am now back up and running, and I figure the problem started when a brief power outage occurred here this morning. Thought I would briefly summarize what I did to recover, which may be of special interest to those folks using a Mac to write to their SD cards: - ran to the store and bought a 4gb Sandisk microSD card. They didn't have any class 10 cards, only class 4, but it seems to work (ordered a couple class 10s from Amazon for backup). - Downloaded onto my MacBook the latest firmware from the bitmaintech website, as well as the SD card image from https://dl.dropboxusercontent.com/u/16075357/bitmain.img.zip (thanks 1l1l11ll1l) - put the new microSD card in the adapter, shoved it into my MacBook, read through the guide at http://elinux.org/RPi_Easy_SD_Card_Setup, and then ran these commands in Terminal: cd Desktop (my bitmain.img was on the desktop) diskutil list (to find the disk name of SD card, mine was disk2, so replace disk2 below with what yours is) diskutil unmountDisk /dev/disk2 sudo dd bs=1m if=bitmain.img of=/dev/disk2 (this took 30 minutes to complete) - once SD card was ready, I opened up the AntMiner, pulled out the BeagleBone card, swapped SD cards and reassembled - powered up, and it started hashing again. Connected to the miner from the browser, uploaded the latest firmware, changed to point to my pool, and everything was golden. Much thanks to all of previous posters that talked about this issue, as your help got me back up in hours as opposed to days. |

http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011EVGA 1300 for $150 after rebate. Might pickup one for my recently received S2. Is anyone's S2 hashrate stable? Mine is kinda jumping around 900-1000gh. Averages upper 900's. I think it's because of the PSU. One card has a faulty temp sensor and stuck at 127. I think I saw a post about that but can't find it. Is there a solution? Should I try reseating it over and over til it might work? That same blade is one that came up as not working a few times. I might remove that blade anyway to see if it's more stable because of the PSU. Mine is still not stable, no matter what I've tried. It clocks down to the low 900's after a reboot in a 24 hour period, although it stayed at around 980 for about three days once. Compared to the S1, the S2 is a fickle beast. I'm hoping the upgrade cards will bring stability, but you don't know until you know. Let us know how long yours stays stable on that reboot, please sir! |

Stop spam posting your donation address and links to your crappy p2p node.
thanks
Come on, man, it's not completely off-topic, just slightly. Edit: His P2Pool front-end implementation is also the best to date, to be clear. |
