Kind reminder: When mining with S7, be sure that you've connected the internet properly and the internet is working well, otherwise, the boards may get burnt easily
I would not take this seriously. This message is not from Bitmain.
They would have used proper channels, and not post a poorly written post on a forum, with an unknown username, lol!
It is a Bitmain account, Janet's successor as she is off doing other things. I've asked them to add it to the BITMAIN signature.
how can we make sure that "internet is working well"?
"oh, no, your miner boards got burned....you did not make sure that internet worked well".
I understand that he means well, but this is just impractical, seriously.
Yea that is a bit unnerving considering no ISP is 100% guaranteed and even my home router needs to be bounced once in a blue moon.
people are being
surprisingly nonchalant about it.
...I woke up at 3am this morning and at first could not figure out why.
then i heard a tiny noise coming from s7 (much less than s5)
;run to it, Internet is down ("internet not working well" situation)
miner is still doing something and fans are on very low, and air is coming out quite hot.
Thankfully, I had a Vornado fan blowing into intake for such situations and to help with cooling, so no critical overheat occurred.
Internet came back within 2-3 min and it was back to hashing.
all i am saying: beware and try to adapt. i can practically guarantee that it WILL happen in large hosting because usually service guarantees just 98% uptime.
If service loses internet, but power is on....
see my old posts in this thread. I wrote here about it but nobody wants to hear me. Photos of burnt S5 are in the thread of the picture your mining... only one time fall me internet connection..
I am skeptical about s7 if bitmain no fix this dangerous FAIL. One mistake and you lose 2000usd(miner+psu+tax). If you put them in the data center, you are waiting for nearly a year return on investment.
I understand him doing this if he already has these on hand and wants to have minimal up front costs. If he plans on adding more rigs in the future, it's best to safely gain access to 240 Volts and purchase "used" server grade PSU's with breakout boards. It's cheaper and able to power more rigs. Yes, gaining access to 240V dedicated circuits may cost a bit in the beginning. Especially, if an electrician is paid instead of doing it yourself. It turns out being cheaper afterwards as more "used" server grade PSU's and PDU's are used to power hardware. Also able to power twice as much hardware than one could with 120 Volts.
