ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH

Be sure to check the firmware version on your B9 units when you receive them. Mine actually is using a firmware from December 3rd 2015. The newest firmware is from December 11 2015. Not sure if they added anything or not but I'm updating mine right now.

Have my S7 running Due to the amount of noise it makes I underclocked it's frequency to 400. Getting 3TH at that rate. Whenever I find a better place to keep it running I'll up the frequency a bit. There's no way that I'll be sleeping with it in my room.

Why not run it in the garage at full blast and get free heat while you're at it?  You're losing money at 3TH.  If you're living in a cold weather area, lower the fan to 30% and see if the temp is within ok range.  IT would be more livable.  You can also buy custom 3D printed DUCT where you duct the Intake to take in cold intake air from outside and push out the hot air to the outside as well.  If you do that, you can lower your fan speed which is the only thing that is making those noise.

I would be careful with that seller on ebay, has only sold one item ever. Only has sold one item in last 12 months and it was stated in feedback that communication was good but shipping was slow after payment.

I used this: http://www.amazon.com/gp/product/B000SL22FW?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
And built my own enclosure for the miner out of cardboard.  Works well enough.

That's very creative.   100 extra points for being resourceful and creativity.

I agree it is a intersting way to get the exhust out.  Are you able to take picture of where they all go to?

I'm curious as far a what you did with other end of duct.

There is a drop ceiling so they just vent above that to the attic.  The building is probably 8 or 10 thousand square feet total so the attic is rather large.

Guys, I need your help, I have a problem with my Antminer S7

I have a group of Antminers S7 in a remote area. and I check on them every day with TeamViewer. The problem is, some miners just turn off by themselves. and I cannot connect with them at all. I cannot connect using their ip on the web or using the cryptoGlance app. Here is a pic of problem with 102 miner:


The temp seems fine. I'm not sure what is their problem. It is frustrating, The only thing that fix them is to go this remote room and reboot them manually. but they sometimes turn off after couple hours, sometimes they don't. The problem is not related to one miner in particular, I mean sometimes 101 turns off, I reboot it manually, then 102 turns off then 104 then, and so on.

I'm using the bitmain power supply APW3-12-1600-B2. The electricity here is 3-phase 230-380v. and of course I'm using 230v for my miners.

I'm dealing with this issue on a daily basis nowadays. Any idea? Has anyone had this issue here?

It happens whenever there is an Internet or power outage even for a few seconds, most of my S7s come back online except for a random one or two. Red light blinks and miner become inaccessible. Only way to revive it is by reboot.

Any recommend what Thermal Glue paste for the S7 Heat sink should they fall out after warranty period and we need to fix it?

repeated many times, ain't broken don't fix it

B8 was 3rd but upgrade to 11th dec fw, no difference imo.

my "B9" comes with 3rd dec fw too & 1 of it has some brownish marks on the female pcie on 2 of the blades heh. very little dust on it. looks new to most but with careful inspection seems like it's B8.

well at least it works well before & prolly lesser chance of RMA. i'm ok with it as long as it's acceptable.

Make sure your units are all on latest Firmware - seems to be less of an issue coming up out of internet failure.

Also you can invest in networked PDU.  Then you can powercycle remotely.

Are they DHCP or static?  You can have accessibility issues like that if you have IP address conflicts.

i just used gorilla glue gel superglue and it works very well.. just remove the old hardened adhesive from the heatsink, and dab a small dot on the center of the chip and make sure you press down firmly

Set the frequency at B9's default of 700 and I'm getting 4.8TH on my S7. Will be watching temps though.

This would also suggest that if your miner didn't ship today, it will be at least 2 weeks until it does? One more difficulty increase for sure it would seem to me. I wonder if this another of those Chinese holidays where a huge portion of the population travels back home from wherever they work.

ahhhhh-shooot!  I have 2 miners in maintenance mode right now with no response to the email I sent 2 days ago.  Dang, 2 weeks!

More like two more weeks of them mining with everyone's miner. We already know they use the miners before they sell, not a bad scheme to get two more weeks out of all the miners that have been sold since there are no refunds anyways. Shady AF.

Thank you for the info. very helpful. Yeah, the internet in my area is not the best. I guess, It could possibly cause this issue. I'm suspecting the PSUs though to be the issue. I remember one of the miners having this issue consistently. It turns off by itself after ten to twenty minutes of tuning the miner on. when I changed the power supply, the miner worked fine without any issues. It was weird. but I'm not sure if that's applicable to the rest of the PSUs. They seem fine I guess.

I didn't update any miners, I will do that. Thanks for the tip. I didn't know that networked PDU exists. They will make my job a lot easier! They seem expensive though.

Do all the effected miners have the same hostname?  If they do; make each one unique.

Yes, all of my miners have the same default hostname.



I'll make each one unique. Thanks!! Hopefully this will help sort out the issue.

I'd say power supply/power quality from source issue.
