Title: Antminee S3+ Asic Status X Problem Post by: caffeine93 on January 24, 2016, 04:23:02 PM A friend of mine has a problem with his Antminer S3+, apparently, one of his fans died. After a few weeks, he noticed some "X" on ASIC Status of his first board, then the next day all of his first board was full of "X" followed by the second board getting all "X". Now, I'm not sure exactly is there any overheating protection in the device or how it works.
So, do you think the board actually got completely fried and dead, or it is that the "overheating protection" jumps in and turns off the chips because the device can't be cooled properly with only one fan? Would be very thankful for any info :D Title: Re: Antminee S3+ Asic Status X Problem Post by: VirosaGITS on January 24, 2016, 04:24:46 PM A friend of mine has a problem with his Antminer S3+, apparently, one of his fans died.

Would be very thankful for any info :D The overheat protection, if its on the S3, would stop the hashboard from running, not kill the chips. And "cooled properly" what temps are the S3 at? I'm pretty sure the single fan should be able to keep it cool enough, although it would spin very fast/loud. Did he power cycle his S3? Thats usually the first thing you do at any first sign of trouble.

If temperature is shown right in gui, protection works. One miner showed 0 degrees and fans didn't spin at all. It overheated so much that cables were about to melt. After cooling down I tried it and hash-boards still worked ok.

Thats usually the first thing you do at any first sign of trouble. I would first try to powering the entire machine off then on via PSU. Not through GUI but the PSU power switch. That should do it on most, some S3's require a little bit of watching others are much better. What PSU are you using? Plugged into 2 or 4 PCIe slots?

He said that he has never overclocked the device and that it was running fine for a while, then after losing one fan, a few weeks later, the X's started appearing and after 3 days, both boards have all X's ever since ???
I typically deal with electronics so he asked me if I know what could have caused it. Now, I don't have one myself, so I don't know how often do these things die all of sudden? Are these ASIC chips very sensitive to voltage changes or anything :-[ Title: Re: Antminee S3+ Asic Status X Problem Post by: VirosaGITS on January 24, 2016, 10:18:16 PM Well, I'm not sure really how he got it all connected.

Are these ASIC chips very sensitive to voltage changes or anything :-[ I think your friend has waited a long time, letting it run when it had a problem, before requesting help. But if you can give us 0 information about what he did, is doing and did not do, we cannot give you any information to help either. 101 Troubleshooting is to power cycle it fully, see if it change anything. Then underclock it, then try a different PSU. Depending on what happen, we can possibly get an idea of what is going on with the Unit. Title: Re: Antminee S3+ Asic Status X Problem Post by: pinhead666 on January 24, 2016, 10:48:36 PM Makes me wonder if the fan is really dead or is there a problem with psu/hashboard? Swap fans or power not working fan direct to test it.
