I'm in the US, where would be the best place to buy an S7 with a credit card?

Amazon.


In other news, got my batch 9 S7s in today. Three of them have issues with board 2. Sometimes it shows up, sometimes it doesn't. Sigh.

Anyways, I was playing with one of them and installed some of these fans http://amzn.to/1OTMULB and surprisingly it stays around 60 degrees. This is a pretty substantial noise difference. I guess you could just change the stock fan setting to 30-50% and make it quieter. But honestly Noctua makes a damn good fan.

I wanted to keep this S7 at my house instead of the data center. I have it outside in a small shed with an ambient temp of around 70 degrees. I'm impressed. I did under clock to 675 just to give me some buffer. The hottest it got today was 63, and has since dropped back into the 50s now that it is 5pm.

On Amazon you can find them but they're still cheaper to get through Bitmain directly. Update on my whole issue with UPS... Finally got a call and I'll be able to pick up my S7 tomorrow afternoon. To anyone that has a B8/B9 already what settings would you recommend for downclocking the miner?

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.

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.

So of course the driver arrived and required me to pay in order to leave the package.  So now I have to see if I can get a refund.  I guess it's fedex from now on.

EDIT: Also my batch 9 IO board only has connectors for the 3 blades.
UPS, DHL and FedEx all have the right to charge customs brokerage fees and processing fees while importing items, while the miner may be duty/tax free they are still permitted to charge these fees as services rendered. They usually don't charge these for smaller orders, and sometimes it's just a wrong HTS code.

Hopefully you got the name on who you talked to.  When possible try to get name and extension.   Did you have the info of person you talked to show driver?  Or did driver not care and said to fight it later?


I got a whole list of names and numbers now.  The last I heard was from brokerage accounting and they said that yes the fee was zeroed but the person didn't do the followup they were supposed to do in order for the delivery center to get that information which is the only place that matters for the driver.  If the delivery center (which is local) says get the money then he has to.  But the brokerage accounting person said that an invoice will be generated and it will show $0 and they will use my check to pay it which will create an overage which will result in an automatic refund.  So I said great, at what point do I call someone when I don't receive a check and who do I call?  So I have a number for that eventuality.

I am curious to see what latest B9's will be if they are close to Feb 5th or if sooner.   Guess we won't know for a bit.

My first B9 order have been shipped 20th. Arrived today 25th after 3 business days. DHL Is really fast. I had to pay 246$CAD for one S7. Not bad for a Canadian shipment. I'm waiting my 2nd order, with UPS this time. I'll see if the customs are cheaper. UPS cost more than DHL on the Bitmain website for Canada shipments.

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!

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

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:


Ahhh! Need to check that out, thanks for the info!

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.

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?!

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?
