Well hell.  My batch 8 has developed a problem.  It started beeping and I happened to be nearby so I checked out the GUI and the hashrate was slowly dropping to zero.  I noticed that one hashboard said the temp was 96 and two of them said temp 0.  So I rebooted through the GUI, it came up and started mining but the temps all say 0 now.  I did a power cycle and same thing, all zeros.  At least it is hashing though so that's good.  It didn't overheat, it is sitting next to a couple other S7's and the temp where they are didn't get up past room temperature and the other machines are fine.  When I powercycled it I did gently move it around to check for a loose heatsink but there wasn't anything detectable, plus I think those were mostly in earlier batches.  But now all zeros on the temps.  Lame.

i`ve add the same issus happens to me on a S4 and a S5, reflashing the machine ( even if it;s the same revision ) cured my problems both times, actually the s5 i had to flash 3 times. let it sit for a day than came back to life the next flashing. try it out.

I ended up having to do this.  After working fine for a couple days with all zeros for the temps the sensors did wig out and one reported 96 and another reported 32 so it stopped hashing again.  The weird thing is, after reflashing it, only those two boards are reporting a temp (a normal one now) but the third board is still showing zero.  Something tells me a reset to default would cure this but I'll wait until the machine gives me no other option.

Bitmain QA, or the lack thereof, strikes again!

I'm gonna go out on my limb and say outloud many many S7's will come to a sad ending soon. What did you expect from a cheaply constructed Chinese junk machines?

Long long ago I was told to reflash when I had a S3 miner with one temp not working... did not fix my problem then.   But some have had luck with it all the way to day's of S3 and temp sensors.  Just be careful as flashing can be bad if something goes wrong.

As long as one has accurate temp you should be fine (not so much if one is to high).  But if you have one working right.... it should be ok.

my batch 2 is still running  this runs at freq 512.5

as is my batch 1  but it never would do freq 600 .   I have run it at freq 525 since October of 2015

Im not a happy customer at all.

We sent 2x S7 hashing boards for warranty replacement well over 6 weeks ago at out own cost.

They agreed to replace both but it took them 4 weeks to admit they had received them.

The 2 replacements boards were sent a week ago and have arrived but they have sent incorrect parts 

They have sent 2x S5 hashing boards instead of the S7 boards expected, im really pissed off now im fed up of being polite with Bitmain as they have been pissing me about for well over 4 weeks now.

How the hell do I get this resolved, not only have they sent me 2x S5 boards they are in terrible condition, very messy with burn marks on them 

I have put pictures below of what's arrived.

Most mainstream consumer goods are manufactured cheaply in China. I don't see your point?

Dear philipma1957,


I am a new miner and Electricity in my country cost for 1 miner is USD 8/month/miner.

I ordered my second miner on 23 Feb.

Shipped on 25 Feb.

And it is in the customs and will be delivered Tomorrow XD.

I paid by bank transfer.

In retrospec, i didnt have any issues with Antminers so far, but considering how such of a pain they are to deal with. I dont think i'll be buying anything brand new from them until they fix customer service and probably base it somewhere not in China.

You do realize that the new S7s are going for 1.67BTC right? No one is going to pay >2BTC for used equipment.

To be honest I have not had an issue in the past, I have been buying antminers and spondoolies tech machines since the S1, bitmains support has normally been ok and I have spoke with Sherry and she always seems prompt and polite, but they seem to unnecessarily drag things on and now they have sent me the incorrect boards which means I assume another wait for them to send the correct ones.

Its just unfortunate that I feel as a paying customer I should expect a slightly better service and hope they can resolve this quickly.

I also admit bitmain zendesk support has been really efficient and helpful in the past, its just when dealing with this issue it has really got me angry.

Thank you,

  and mine are yet to ship.  I guess my mentioning they owe 150 usd  me from batch 1 caused the delay.

here are my batch 11 payments.

sad they were a very good company at one time. They actually tried to build good gear and do decent customer service.

[nhando]

They go by orders of payments.  All my orders usually ship based on order of payments based on history.  My order which was paid and acknowledged on the 23rd haven't ship yet either, so that means they probably have a small back logs.  It's the weekend and I don't think they will resume shipment until Monday.  They do have until March 1-5th to ship the boxes, so the fact that they are shipping earlier may be due to lighter than normal sales volume.  Now that BTC is up nicely, who knows, maybe they want to mine with our boxes for another few extra days.  =)

Well hell.  My batch 8 has developed a problem.  It started beeping and I happened to be nearby so I checked out the GUI and the hashrate was slowly dropping to zero.  I noticed that one hashboard said the temp was 96 and two of them said temp 0.  So I rebooted through the GUI, it came up and started mining but the temps all say 0 now.  I did a power cycle and same thing, all zeros.  At least it is hashing though so that's good.  It didn't overheat, it is sitting next to a couple other S7's and the temp where they are didn't get up past room temperature and the other machines are fine.  When I powercycled it I did gently move it around to check for a loose heatsink but there wasn't anything detectable, plus I think those were mostly in earlier batches.  But now all zeros on the temps.  Lame.

i`ve add the same issus happens to me on a S4 and a S5, reflashing the machine ( even if it;s the same revision ) cured my problems both times, actually the s5 i had to flash 3 times. let it sit for a day than came back to life the next flashing. try it out.

I ended up having to do this.  After working fine for a couple days with all zeros for the temps the sensors did wig out and one reported 96 and another reported 32 so it stopped hashing again.  The weird thing is, after reflashing it, only those two boards are reporting a temp (a normal one now) but the third board is still showing zero.  Something tells me a reset to default would cure this but I'll wait until the machine gives me no other option.

Now the last board that was stuck at zero is reporting an erroneous temp of 127 and miner won't hash.  I tried multiple reflashings, a couple of resets to default.  No love.  POS.  It mines if I disconnect that board but 2/3 hashrate is never going to get near ROI on this thing.  I tried swapping the control cables and the problem goes with the hashboard.  I have a hard time believing it is a hashboard problem though because all 3 hashboards have done this at some point.  It's just that two of them stopped doing it when I reflashed the first time.

EDIT: Well holy crap a bit of luck!  After running it for 20 minutes or so with just two boards (the bad board was disconnected from the controller board and the PSU), I figured what the heck I'll connect it all back up and give it another shot.  All boards working and reporting correct temps.  Looks like the hashboard needed to be left off and unpowered for a period of time.

EDIT2: Spoke too soon.  No sooner did I have that board working then the other two started reporting weird temps.  After letting the whole thing sit I am back where I started with the original board reporting zero and the other two reporting normally.

[philipma1957]

Maybe you have a bad cable?

[not.you]

I tried swapping the entire cable at one point too.  The problem definitely went with the hashboard at that point.  I got tired of messing with it for today.

The setting in the GUI to stop mining if it goes above 80 degrees is always on, unchecking the box in the GUI does not seem to turn that off.  I am going to see if I can find it in the filesystem and disable it.  The boards hash fine, the only issue is the temp reporting is unreliable and erroneous and when it pops up with a temp above 80 the whole thing stops hashing.  I can live with bad temp reporting if it still hashes.

EDIT:Something really curious about this machine's behavior, the original issue where the temps all went to zero started when Kano's pool had a brief downtime and the miner failed over.  The issue today where the zero temp blade went to 127 coincided with Kano's pool finding a block.  Immediately after the 79% diff block is when this miner stopped hashing.  It's almost like what cgminer is doing on the box is affecting how that temp reporting is working somehow.

EDIT2:I SSH'd into the machine and I see that unchecking the 80 degree box in the GUI makes a corresponding change to the cgminer.conf file so right now I have my doubts that I can figure out why that isn't working and change it.

[JaredKaragen]

anyone else notice that when you have two different pool URL's, the "bestshare" value never shows?  I think after it has mined from both pools at some point.  It will show bestshare for the only connected pool until then (weather it be the primary or failover that's the only one that has connected)

This has been an odd bug i've noticed for a while now.
