ANTMINER S5: 1155GH(+OverClock Potential), In Stock $0.319/GH & 0.51W/GH

[VirosaGITS]

It was easier to just move a good working beagle-bone to another miner. Booted right up and started hashing good, so this does confirm a bad hashing board.

Never wanted to risk popping out the BBB, thanks for telling me its doable if you have a spare. If its any consolation, the dead PCB is sellable for parts. If you can't fix it, you can sell it easily on the forum.

I would not be surprised if you received PM's about it soon, if you have not already.

I asked my Dad to take apart his bad rig and put it back together. Sometimes just doing that has helped me in the past. The daughter card has 4 connectors on it, so I would imagine it can run 4 hashing boards. I have tested those connectors a year ago with just connecting on the same miner and worked as normal but since they have been running so good I don't touch them. I'm just trying to eliminate everything. There's also a 4-5 pin cable going from the daughter board to the hashing board. Not sure what that is yet.

Yes it can run 4 boards at the same time. But according to Bitmain, thats the way to go (turning the board over). Maybe each side are run through different electronics, so if it dies both board sockets on one side could die.

But since we already know its the board that has a problem. You could try to reflow resoldering. And the 4 pin from one of the board to the controller is there to power the controller.

Heylo folks,

 Looking for a little help. I didn't notice when, but sometime within the past month or so, one of my S5's stopped hashing or would produce minimal hashrate. Today I reset it back to the factory default and it won't hash w/ the default config. On the Status dashboard, it shows 30 asics on one board/chain and 26 asics on the other.

 There's nothing visually wrong with it, to my eyes. Can you provide me with some guidance?

Swap PSUs, cables, and/or controllers with other miners, try to isolate the issue. It would be unlikely for both hashboards to go bad although not impossible. Take the plastic guards off and look closely for any physical damage/burns. That's roughly where my knowledge ends , maybe others can help more.

One of the weirdest issues. If one hashing board dies out, you'd figure at least the other one will work. All configurations were tried. Different controller, cables, PSU. Ok, so concluded that one hashing board died. Fine. Thought could get the other "good" board hashing, but that won't even hash. Restored image from SD card. Tried different firmwares. The webGUI pages come right up fine but hashing speed just indicates 0. The other "good" board doesn't want to hash either, but indicates all zeroes. The controller was put on another rig and hashed fine. The only thing I could possibly think is this rig got ZAPPED electrically somehow.

This is the log, hard to dicypher if you aren't a programmer.

What happens if you just disconnect the bad board?

[Tupsu]

I've fixed this before, but forgot what I've done. Can't remember at all. All dashes on the first row, and then sometimes a few X's on the second row. Sometimes starts hashing around 300-400G, but never above. Tried another PSU. This is my fathers rig, so I haven't asked him to try another controller. I'm guessing controller, hash board, or possibly a cable, but I doubt it is a cable. Any guesses? I just have remote access to it right now, but can ask my Dad to try a few things.

First thing i would do is turn the controller 180 degree and effectively swap the blade. If its now the bottom blade (on the webgui) thats dead, then you know its not the controller.

Assuming he tried a power cycle already.

You have only 26 chip on this board.

Nothing else I could do for that rig. Just died. Oh well.

Nothing happens. Trying to get the good half hashing but won't. I do think it got zapped.

Any idea how to solve this?


All ASICs seem to be ok, but the miner does not start hashing. I read about reflashing firmware. Where can I find a tutorial to check this?

Use your own Antpool username and not Bitmain default username.

Very strange. My Dad has an S5 with a bad hashing board and the other one won't hash just like your issue. I did submit a ticket to Bitmain, but I doubt they will send a response back. Once these guys get busy with shipping they tend not to add more help. Remember Janet, Yoshi? I've communicated with them privately back when I was getting my S5's, but haven't seen them on any threads.
Reflashing is easy. Just download their latest firmware from their support website then go to the UPGRADE page and select that file. There is also a re-program, which re-writes the NAND/non-volatile memory from a micro-flash card. You use a utility like Win32diskmanager and write the restore file to the flash card, insert it into the slot on the beaglebone board and boot the miner. Should re-program the miner, will have to configure your settings. Can then re-move the flash card.

BTW, if anyone has any S5 hashing boards that DO work please PM me. Trying to help my Dad get his S5 running again. I'll give Colorado a call, but I don't think they sell anything, just support.

Thanks.
I'll forward the info/price to my Dad and see if he is interested. What version is on the boards themselves?

Sorry, I just noticed the BTC. I rushed viewing the post. I'm basing my value in USD, so that comes to over $180. Do you mean one (1) hashing board or two (2)? I only paid little over $300 for each S5 when they were selling months ago. In you do indeed mean $180 for (1) one hashing board that's way to much. I have a feeling you are including a very expensive shipping method out of the US, right?

Now I'm thinking of maybe selling off my S5's if I can get prices like that.

Shipping with air mail, 7-9 working days.

This is OK , if it is too expensive for you. I've been selling for the same price S5 blades  to Canada and to the US  even in this month.
It's not my fault that BTC's price rises, and now consider all buyers the price of spare parts with USD. She still mine BTC,  and I can sell the whole miner for 1-1.2 BTC I do not have to sell it in  parts.

My only reason for selling is that I do not have more power
and  Bitmain already sent me 2 xS7 from Batch6 and 2 x S7  from patch 7. I did not expect them so early.

what firmware version you use for it?
i already detached 2 broken bitmain chipset, but in the webgui still show 30 chips
