Ok now i'm sure it has something to do with the SD card or the IO-board. I started the damn thing and after a few seconds i pushed the sd card in the socket. And boom it booted  So i had to power it off and put the lid on it and now i'm back from where i started  |

Hello fellow miners, I have a semi dead S2, i think it's the SD card. First I removed the date from the filename to get "initramfs.bin.SD" than I tried to write the firmware from Bitmaintech on it with Win32 disk imager. It writes for a few seconds but after that the S2 still does nothing with the card. I even tried the image from |1|1|? but still nothing. After writing i can't open the sd in windows, not with the original or the other from that |1|1| guy. Before i could just read it and see the files on it??? Help?  |

I tried the image from 1l1l11ll1l but for my it did not work.
win32discimager writes for a few seconds but after that i can't read the sd card.
There was also a other image ( updated? ) and that one worked.
It took a few minutes to write that one.
I have just send a email to bitmaintech to ask about this booting problem.
When i have found the problem i will post it in here.
You will probably need to format the SD card properly before writing the image or it might not work (it's partitioned). Download a SDFormatter to format the card and make sure you see the full memory available before writing the image with win32diskimager. Sounds like you got it working though... if you did, you should make an img of the working card and write it to a spare or at least to disk, to make any future resetting go quicker. Yes i can see the files on the SD card, both on the card i made with the diskimager and on the original one. btw, the sd card i used came formatted, i will try SDFormatter tonight to be sure. Thank's for the advice. |

I have a Antminer S2 from the second batch, it was all fine for a few day's after putting the blades back like most of you  Until today, i restarted the damn thing and now there is nothing but blue on the screen. The original sd card seems to be fine, new msd card with a new image does not help. I even tried with all the blades out, only one and half of them, still nothing Do you guy's know what could be wrong? When I've had this problem, it's been the SD card, try re-imaging it with the image from 1l1l11ll1l. If you need to power your machine down, first eject the card (no need to completely remove it), then power off, then push it back in and power on again. I've had no more problems since following this routine. I tried the image from 1l1l11ll1l but for my it did not work. win32discimager writes for a few seconds but after that i can't read the sd card. There was also a other image ( updated? ) and that one worked. It took a few minutes to write that one. I have just send a email to bitmaintech to ask about this booting problem.

Yes i know, i mined the coins with S1's to buy the S2 on 16-03 for the second batch. The S1's where great but this I hope it's something i can solder back, that won't be any problem for me. Even if it's a bga or something like that. On the controller board are 5 led's, only one of them is green. it's the led with R41D5 marking next to it. Any thoughts? |

Yeah i was waiting for a reply on my post about the PS3 PSU so i was quick.
I understand that it's not good to use all the power because that will stress the PSU.
3 antminer's should be fine, maybe the fourth will be a bit much for that expensive PSU.

Hello, I have a few PS3 PSU's to use for mining if it works. I found pin 1 and 5 must be shorted to start this model: APS-227 +12V DC output @32A makes 384W right? Connected the + and gnd to the first blade with thick wire. Second blade makes contact with the first by using a PCI splitter cable. What do you guys think about this?
