I say, indicate more than one pool, then it will beep only if internet connection is down.

The Checked box for my S3 works. All 4 of my S3 did not beep, only the S7 as I can't make that change.
December 25, 2015, 12:02:45 PM
All - Where did they put the Beeping = False / True for the S7 configuration. For the S3 it was conveniently in the Miner Configuration tab but for the S7 it's no longer there. Failover or Balance is also not an available option on the configuration tab as well on my Batch 8 S7. Kanos Pool was down this morning and that woke up the entire family with the beepings. Wife freaked out thinking we have a fire and now she hates this Heater she calls it. Hahaha
the check box on the s3 and s5 never worked... it still beeped if the pool went down.
putting a piece of duct tape over the speaker works tho..

I buy ALL my stuff from Yoshi in Bitmain Denver.
NEVER have a problem with customs. He imports, you get your miner shipped from Denver. For about 1 1/2 years now. Excellent customer service.
Does he charge standard list price for the miners, or sell at a slight premium? NEVER have a problem with customs. He imports, you get your miner shipped from Denver. For about 1 1/2 years now. Excellent customer service.
You pay premium if you want USA warranty and/or pay with PAYAL USD. I use AMEX through PAYPAL usually.
$100 per miner with USA warranty. Worth every penny.
Just sidestepping the customs headaches is a blessing.
Just had a batch one replaced, only down 6 days, one or two days was me trying to fix.
Where could I contact him?. To buy a miner.
If you are able to order from there please let us know. I know Wolfen has said he get's from there. I could have missed it but I sure have not seen a big jump of people saying they are able to order direct from US.
For the rest it's been website or possibly email if really big sale. But I can't imagine if you buy a few US doing the selling but I could be wrong.
I tried to order from Bitmain Denver on several occasions with no luck. Not sure if it was Yoshi that I was dealing with but it was the same guy that answered the phone everytime; typically they never answer the phone or return calls if you leave a message. I had 2 open tickets, sent all my information so that I could buy using Paypal but he kept telling me that it would be a few more days for some reason. Batch after Batch was selling out in the meantime, I got tired of being strung along so I drove an hour and half from the small town I live in to the nearest city with a bitcoin atm, purchased btc, and then ordered directly from Bitmain China with ZERO issues. I have done that 3 times now. Btw, if anyone can suggest an easier way buy btc please pm me.

They finaly relleased them 
. I sent them the documents from my s4, and there is clearly stated that they are computers. They were not purchased from Bitmain directly. Thanks guys

Just give them the link to official S7 page.it explains everything there ...it s a mining machine
If possible power up and show them the screen of the BITMAIN IP address...
if all fails.... show them the power supply.... and the network cable...

BITMAIN co-funder gave an interesting speech about the bitcoin space in china. Here's a link if you're interested:

Yoshi has offered some direct USA sales. I have exchanged emails with him and he would allow me to go via USA if I want to do so.
I am not exactly a power power but I do buy a lot from China. Yoshi and DzCoop (Matt ) did a warranty for me. One timeI had an S-1 arrive with broken parts.

What is the normal process for Custom / Tax for these Antminer from BitMain to the US? I'm seeing no standard methodology for Custom tax / duties, etc. I paid $0 other than $10 to cover the receiving end for Bitmain when I went with the lower cost shipping with FEDEX. My brother in law paid Extra to use UPS to avoid any delays with custom per Bitmain's warning on their site, but he got hit with $16 Custom charge per S7. I thought US, we don't have to pay the custom fees per what others reported on other threads? I'm getting ready to buy another few B9 and want to know the best way to avoid surprise charges (ie Buy via wire vs BTC, use FEDEX, don't use UPS), etc. What's everyone's experience and what Delivery company did you use?

How low can they be clocked from the firmware ?
Id like to know what the S7s consumption at the wall at its lowest setting.
Id like to know what the S7s consumption at the wall at its lowest setting.
100M is available hahaha
maybe u can try & tell us the results ?
power consuption is mostly linear if the chip voltage is unchanged. even at 100M you might be 0.25-0.27w/GH still (I personally know as low as 350M works on the dropdown list, no consumption numbers though)
looking at the numbers provided above, seems like at low frequencies its closer to 0.36w/GH @100Mhz (240w/670GH). server supplies likely have a 5-10% lower efficiency at <20% load, so a better psu (such as a 650W gold-ATX) might only draw 220W under the same conditions.
Consider that fans are ~5W+5W, and the controller board likely draws 5-10W extra, and the hashboard-level draw is closer to 200W, or 0.30W/GH

Just to add in, this is on a S7 B8 on a stock DPS2000BB PSU 
thx for the results. is it possible for you to up the volt on the dps to +12.5V & some data logging ?
@E do u have 162 chip to test ? & some results please if you have.

Unfortunately this B8 is the only S7 I have around. Just haven't been swayed by their pricing but the B8 finally dropped to where curiosity got the better of me.
I definitely will measure at 12.5V and I'd love to get data logging setup -- just need to put hands on a gpib-usb. I've observed a few funny lower current transients with lower hashrate but no ASICs x'd out and I'd like to capture that happening in a log.
The xitron box will even transfer i.e. voltage/current waveforms sampled at 18bits/500kHz, with fsample derived from any fundamental present (allows use of rectangular windows during DSP yada yada...); just waiting for DC shunt now to be able to do direct PSU / miner system efficiency measurement (simultaneous, synchronized, high-frequency capture of V and I on AC line and on 12V line). I've had this box around for a while but I'm glad I finally got it calibrated and setup!
