fan1 at 4,440 and fan2 at 4,080

i have gotten word from bitmain a few times now and they are having me send back 3 boards out of 6.

they said it's a problem with the temperateu detector on the hash boards.

now i appreciate their follow-up and the fact that they seem to be able to fix this for me.

But in the meantime, i have to cover shipping, plus i have 2 miners down to hashing.  At the very least they should cover shipping, as i'm already losing money as it is.

Not cool

running at 100%

That's not good news!

Exactly what mine was doing, aside from the being on a different board.  I had board 1 with temp and none of the others.

Is your machine also blinking and beeping at you?... I see it's not hashing like mine.

I sent them an email, and after realizing i'm only getting 1 reply back a day, i entered a ticket also on their "support center", it has gone unanswered so far.

In the meantime, my other miner is also showing up all 0s for the temp reading, so i'm no messing with it yet, until i get more feedback from the one that's currently shut down.  In order to prevent any further damage, but i'm wondering if i need to send both back at this point.

Please let me know if you hear anything and i'll do the same

So i'm having the same exact problems.  I've opened a ticket and still waiting, as they only reply once a day, it's like watching snails crawl.

have either of you heard back from bitmain on what's happening here?

I'm getting a reading of 0, and now it has resulted in one board beeping and stoped hashing altogether, it only resumes once i disconnect that board.  But i'm afraid others will follow.

I've updated the firmware, and tried any sort of reboot i can think of.

i have also increased the fan speed to 100%  and nothing works

thanks for the feedback so far.

i did buy from bitmain, and i have already began the ticket process.  i have replied to everything they asked but getting a reply back has been slow.  I only noticed the s5+ board on my S7 after the last set of replies i made, so i was curious to see what other people on here with s7s had.  If everyone is getting the same board, then it seems they just reused it for everyone on the new models.

i have basically tried everything i could on my end updating firmware to shutting the machine down over a long period of time and rebooting afterwards.  No matter what i do, when i boot back up i get beeping out of the 3rd board and it always displays 127temp.  machine only runs if i unplug that board.  When it's up all the chips show up Ok, no Xs.

But when plugged back in, it just stays red, beeps and won't hash

Hi Everyone,

So i've been having problems with a new Antminer S7, it's not reporting board temp and then shutting down even thought i'm not getting over 38-42 temp.  Sometimes it reports, other times it just shows 0.  and now i'm 100% shut down and it continues to beep.

While doing as much research and looking around as i can, i came across this small discrepancy.  The control board shows S5+ V1.6  despite this being an S7 (see photo below)

What does everyone make of this? Mistake from Bitmain? are all your S7s using the same S5+ Control board and what i'm experiencing is unrelated?

In the meantime, for info on what i've setup so far is:
I have updated to the latest firmware from oct. 23rd.
I'm running at the default 600 frequency from S7 Batch5
and fans were running at 100%
and it's PSU is the EVGA supernova 1600w G2

I got about 3 days work out of this before i started getting these shutdowns (started mining on saturday).  The rig is setup in a well ventilated warehouse space, so plenty of fresh cool air.



Thank you in advance...

I'm having the same shutdown problem, and after seeing this post i checked, and i'm have the same thing.  Both my S7s come with a board that says S5+ control board Version 1.6

you are not alone in this.  i'm searching everywhere for an answer to the same problem.

Both my S7s i purchased on batch 5 are doing the same thing.  I have them running with 100% fan speed, and there is no way they are overheating as the whole area is very well ventilated (warehouse space).  I'm running the miners on the EVGA supernova 1600 G2.  And i'm not getting a temp reading on any of the 3 boards.  Then the miner drops off, keeps beeping and the red light's on.  WHen i check the miner status, i now get a temp reading of 127.  I don't know if the heatsinks are falling off of not, everything looks in perfect condition inside.  At this point now, i'm not capable of turning one of the miners back on unless i unplug the 3rd board.  Then i get about 3TH out of it instead of 4.8.

I don't know what to make of it, customer service is slow on email, but i'm waiting to hear back from them after submitting as many screenshots as i could of the miner status.

PMed you

Thanks Finksy
