Few days ago 15 pics of S7 B8 Arrived, and all of them at least one browny connector, some had 2 and more..
I pretty concerned about it Sad

I'm assuming that Bitmain uses their own 1600w PSU. I wonder if those are the ones that are making the PCIe connectors brown. Makes you wonder about the quality of their PSUs. I've never used them and I've never really heard about any of them failing but maybe I just missed those posts.

Just got a brand new S7 arrived from Bitmain bought by a hosting customer. Just out of the box and I see one of the power jacks on the middle board already has a bit of heat browning to it. Not terribly impressed by that.

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?

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.

This days the routers give DHCP from .100 range, so maybe that conflicts in your situation. I advice you to change all the ip adresess in 10 range. Example 192.268.1.10 .11 .12 and so on. Hope this helps. If you know how to enter your router go and see what is the DHCP range. Avoid to put that adresses

Thanks for the suggestion. I just checked my router and the range there from 192.168.1.1 to 192.168.1.254
It could help though to give it a shot just in case.

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

Sorry, do you mean the problem from Bitmain PSUs the I have, or the electricity company in my area?

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

All of my miner have static IP

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.

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.

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.

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.

Dear customer ,We'll have 15 days off due to the Spring Festival from 29 Jan to 13 Feb.please do not ship defective parts back during this period.
if your miner have any issues ,please contact us asap ,we'll provide some trouble shooting steps to see whether you can fixed it yourself.
if you have confirmed the defective parts ,please refer to website：
https://www.bitmaintech.com/workOrderGuide.htm and send me email with the RMA info first , be sure to provide me the update info about the tracking number after you ship them back after 13 Feb.
Much appreciate for your cooperation .

So yea... 15 days of sitting on defective parts. What a great company lol. This will definitely be my last order from Bitmain, would rather fork over more for an Avalon tbh.

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.

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.

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

Thinking of using this

http://www.amazon.com/Arctic-Silver-Alumina-Adhesive-AATA-5G/dp/B0087X725S/ref=sr_1_1?s=pc&ie=UTF8&qid=1454048850&sr=1-1&keywords=thermal+adhesive

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
