When can a member have the full privilege to post the picture in the thread?  Senior level?  It's a pain to use Imgur and have to request others to quote for the picture to show.  Here are a few of my batch 9 S7.  I under clock 1 of the box to 675M just to see how much less Hash Rate I would get.   I do have 1 x S7 that is reporting .3% error rate that is not shown here but even so, it's hash rate is up to par.  I still have many more boxes to configure and power is not fully ready yet.  Notice all of the FAN speed is all over the map in RPM?  There is no consistency even though all of them are set to 60% manual speed.  The only time I would expect for this to happen is a person swap to different FAN type but these are all brand new OEMs.   I noticed some of the S7 even with the same settings can run 5-7C hotter or cooler than the others.  The ones that runs hotter are generally 5% faster then the ones that runs too cool.

Thanks OregonMines!!!  Finally!  Happy Days....

I see that Bitmain has added to it's S7 spares with the IO Board for $17. Unfortunately they have gone with the version that only has 2 fan connectors & 3 hash Connectors. Have they made a range of spares available in the shop for previous Miners, or is this a first?

I think it's the first IO board for them to do this with.   They have been adding replacement parts here lately which I really do like.   They have always been more through email which has to be a pain for them.  So I think it's a better system overall.

They seem fair on price compared to what they could charge.  So I'm thinking positive overall.

The reason for the delay in customs clearance International of your neck is described below. Where possible, FedEx provides tips for troubleshooting


1. The importer must provide the number of tariffs. Will the exporter.

for me are idiots, those bitmain
Now my shipment is stuck in customs

I had no problems in customs, when I made the customs declaration myself in Finnish Customs' internet service.
I provided them info with appropriate TARIC-code (8471.49.0090), paid VAT 24% and that's it. Took less than 10min.

Before buying another miner, go learn some english!

Italian customs may suck too, not just bitmain!

you've tried to learn Italian?

My B9 S7 will be here today so now both of my S3+'s may be moved to mining solo as lottery machines. I'll post status of the miner when I get it running.

[hawkfish007]

B9 has been shipped and picked up by UPS for delivery on Jan 27, order date Jan 16.

[djroadking]

UPS driver came by and wasn't able to find my S7... He told me that he may have to come by later. UPS gave me a scare a few years ago when they lost a guitar I build for a friend... I'll update as this goes along. If it was dropped off at a UPS store I guess they'd call or something?

After setting up proper monitoring (screw you, Minera!) we found out our HW error rates are way low, in the order of 0.0018%. So thrilled seeing such low numbers.

As for the temps, our cooling setup isn't entirely completed yet. What is the temps you usually "accept" your blades to run at? I was seeing 63c on some miners, is that within reasonnable range? It's safe up to what temps?

Thanks for the help!

Hi all

I have a issue with one of my Antminer S7's

I ordered two at the same time and they have been working perfectly for about a week until in the middle of the night one of them just started beeping,
It stopped hashing and wont respond when I try and log into the web interface
Obviously I have tested its ethernet cable, turned it off and on again and even attempted a hard reset via the recessed button on the side.

Once its completed its "reset" it just continues to beep with a solid red light?

Any advice on who I can contact in Bitmain regarding this unit as its effectively dead?!

Opinions vary on this.  But it has been observed with previous models: S5, S3, etc.. that lowering temperatures after a point also lowers the hashrate.  So getting the absolute lowest temperature you can on those miners is not the way to optimize hashrate.  I believe it is probably true of the S7 as well although I haven't run one in conditions where the temps get into the 40's as reported by the GUI.  I am running mine in an environment where they are in the 60's most of the time.  They do occasionally get as high as the low 70's (73 being the highest I have seen) on one or two boards for a few hours during certain times of the day depending on the outside temps.  If they spent more time in the 70's I would probably make changes to bring down the temps.  Previous generation miners were pretty much designed to run without AC but with some mechanism in place to get rid of the hot air.  So in other words you could run them with room temp air going in without an issue.

Makes sense. I had set my alarm tresholds on our Nagios at 60 celcius, I will have the alarms go up to 67 for warning, 70 for critical.

The room runs at 25c intake temps, 35c exhaust temps. Monitored through RoomAlert 32w and their sensors. It's been "hotter" the last few days outside peaking at -3 celcius, at -20 celcius we intake 12-16celcius air inside and they tend to run at 40-45 degrees when that is the case.

Thanks for the input.

louiseth1, what are you using now to monitor your miners?
You are using Nagios only to check temperature, right?
Thanks.

UPS wants to charge me a fee for import duties.  This may well be the last miner I buy from bitmain since they obviously can't get their shit together with the paperwork.

Was it over $2500 total purchase or below.  Fedex seems like the bether route.

Just one miner.  It must have been around $1130ish at time of purchase.  So looks like the duty comes out to around 3.15%.  I have never had to pay a duty on miners before.  I saw that conversation about HST codes but I had already made the order by the time people were talking about it in the thread and I was unable to go back and change anything to add it to my order.

Call the number on the invoice and tell them what it is, UPS will refund, at least they refunded mine.

Well after calling UPS many times, waiting for a call back and not getting it, then calling again, then calling different departments, I was told the charge was being removed.  The miner hasn't arrived yet, supposed to arrive today so we'll see if the driver gets the info that there isn't supposed to be a charge.  The lady I talked to asked me what a bitcoin miner is and then she put me on hold and when she came back she said she "added an entry in the system for bitcoin miner that has no duty fees".  Now I don't know if that is specific to my delivery or if that means a UPS-wide thing so that this doesn't happen with packages labelled "bitcoin miner".  It sure seems like when you call them, you get told entirely different things depending on who you talk to.

I should also apologize to bitmain for my original post too.  This does not appear to be their problem after all, it's a UPS problem so apologies to bitmain on that count.

No, I am using Nagios with a set of custom plugins I have made pulling the cgminer-api of the S7's. I also graph all of that in PNP4nagios, graphs which then get included in our in-house "farm management" system.

See an example below:

Most likely was specific to your delivery.  I doubt they did a blanket rule for everyone.   If you are in US and get a decent sized charge call the carrier, as you really should not have that much extra cost over shipping if any.

It is normally a mixup and can be fixed by calling when it does happen.   Some other countries are stuck with vat/import taxes so this calling will not work for everyone.
