Topic: Antminer S7 turned off automatically (Read 3277 times)
I would say fans at 30%-35% is manageable for your ears. make sure the temps dont go too high, 60-65 should be okay. That way you dont have to suicide yourself
suddenly i noticed that my hashrate droped from 4.3 to 3.9 and i took a look to the s7 and saw the LED is off on one of the hashboards but after 40s it became on again and my hashrate increased to 4.3
what caused that ?
what caused that ?
yeah it drops connections some times.
are you still mining on the site with 250 + ping times
long ping times can cause a drop out of 1 or more boards.
did you try a different pool to see if you can get ping times under 150?
Probably a good idea to load up a computer, go to the command line and start to ping all of the main pools. This will make it easier for you to find the onces with a fasterping speed (geographic location is not usually a factor as different cabelling is used!)
Antpool and Slush's pool are quite fast (these are the ones that I have tested through normal command line pinging though it depends on where you are and your internet provider and speed).

If I have this correctly, computer power cords expect to get 17-26V of power from AC (at te wall) and would also expect to only have 70-100W going through them.
Meaning:
The antminer S7 is 1200/100=12x the currente expected through the computer PSU.
You may have to go to the website of the company the PSU was bought from (not Bitmain) and purchase the correct extension.
As for your computer, the first time you plugged it in, it may ave been connected wrnge but the fact that it overheated means that tthere was too high a curent going through it.

he got a good power cord with proper gauge his miner now works

why is my hash rate is so unstable
freq is 650 and fan speed is 3,720
is it because of my latency? (I'm suffering from unstable latency)
here is my ping chart

set your miners freq lower if you are freq 700 set freq to 500 and set fan speed to 30
check your temps with freq 500 and fan speed at 30
if they are 60c-65c you are okay.
this will reduce your power use and reduce your hashing speed
you show freq 700 >>>>>>>>>>>>>> drop to 500
the fans are at 4000rpm = loud >>>>>>>> drop to 30% = 2800 rpm not bad
temps are 50c really good >>>>>>>> tell us what this goes to after 1 hour
if freq 500 and fan 30% is under 60c after 1 hour
try freq 512 and fan 30%
if freq 500 and fan 30% is 65c or higher
go to freq 500 and fan 35% ======
I set the freq to 650 and set fans to 70
Boards became cooler but the fans speed is still the same
yeah there is a trick to the fan speeds.
65% is full speed.
try 50% you should drop rpm to 3300 let me know if temps are at 60 and fans at 3300rpm
i think that 3300 rpm will keep you cool at freq 700
i am making a guess to correct fan speed but i should be close

I don't wanna reduce hashing speed
Frequency is on 700 now and boards temp are about

Now i tested the 1.5mm and it is working perfectly but the fans noise are driving me crazy
It's like Lavendre Town Syndrome i may commit a suicude

can i reduce the speed ?? its very bad

as I said earlier, the bitmain PSU doesn't use a C19 cable, but a standard C13.
The power cable is fine, you do not need a C19 adapter.

by let's be realistic, we all know who use poor quality materials, I bought a couple of times by the Chinese, and I am talking about small equipment, houses for hardisk with power, even power cables for psu,
result?:
the houses for hardisk and burst, even burning the hard disk,
the power cord had become glowing, and very warm.
and I guarantee you I'm not the only one.
It is not a question of racism, but make a comparison with other products in the world,
type america, Italy, Germany, France, etc ....
almost everything is produced in China because it costs very little work, that's why they're cheap, but they use bad material I guarantee 100%
my post is deleted now that I know, but the truth must be told.
I'll take an example
in china producing the tomato cherry, which is unique in the world is produced only here in Sicily.
Imagine this product as they do in China?
let's stop by

do not buy Chinese equipment, which fall due
Think about this comment for a few seconds and I think the humor will come to you. Chinese equipment..... that is where most miners are made
.So the gear your powering in almost all case is Chinese made on miners.

Before powering it up again it was very emphasized on antminer s7 to give a shake to it and check if any of tge heat sniks have become losse or fallen
I gave a shake to it and I felt a little that there is something in device which makes sound. Do you think I should open fans and take a closer look at hashboards ??

Yes but get a strong flashlight do both fans and look all the way through the miner

I don't see why the 1,5mm2 would only be rated 10A.
Yes, that's strange

After 4 hour of looking in stores to find a 1.5mm^2 cable

I have a couple of spare power cables with 1mm2 internal wires that I can try to send you from France if you want.
I'm using 18AWG (0.824mm2) for my S3 power suppply (850W)
and as they have a EU plug, you won't need the travel adapter

that cable for your power cord is totally and completely not acceptable.
1.4mm is good .75mm is a fucking joke.
FIRE FIRE FIRE!!!! can I make it any clearer then that?
tell me your country and I will search a proper power cord for you. As dying for mining coins is not acceptable.
DO NOT PLUG IT IN WAIT FOR A NEW CORD!!!!!!!!
I'm in Iran 1.4mm is good .75mm is a fucking joke.

just fucking cheap chinese cables are availibale here
I told the sellers houndred of time that i'm gonna use a 16A device which is going to be 24/7 on, and they all gave me this fucking cable
i just tried to test the PSU
unpluged all PCI's then pluged it to power but the fan didn't run
is iit ok ? or the fan should start ?

I would first try eliminating things. Can you try without adapter?
See if it powers up without it go to the IP and access it and see what miner say's. If it works without adapter then look at cable next and see if it get's hot. If so stop using it if truly hot to touch and get a better cable.

If the power cord got very hot, then that means it's either faulty or too small or gauge to handle to power being pulled through it. You need to get a new, bigger gauge cable to start. Then you can determine if there was damage to the miner or psu (probably not). The miner likely shut down due to lack of power due to the crappy cable.
If the power cable got hot where it plugs into your adapter, then it could also be caused by the adapter.

That is the problem it could be either of these. The adapter just does not appear to be something I would send 1300 or more watts through.
The cable I think is to small of gauge most likely. Getting hot is a pretty good indicator of this. The best of "local markets" might not be good enough I order a decent PSU cable from amazon when I'm getting one for a server PSU like the bitmain one. I have a feeling most local markets unless you have a good computer store is not good enough.

The other thing is it sounds like your using your power cable from a PC for the bitmain server PSU? I personally use a nicer heavier gauge cable for my bitmain PSU's that goes into a PDU.
If your using a cheap power cable i could see that as a reason for it to heat up possibly. Don't know enough to say since don't know what your using. There are different AWG cables. Some are much nicer then others.

that is what i'm using 220V & 10-16A & 3*0.75mm^2 it was very hard to find a cable which support 16A and the yes it was very cheap but the was the most expensive in those cheap cable
and it is impossible for me to buy a PDU
do you think the antminer has been damaged ?
Where do you get stats for the surge protector/adapter. Just looking at that thing it looks pretty cheap. Is it truly rated for this kinda power?
And I could be off base and it is perfect. Just have not seen anyone post before that I know of using a 8 dollar dollar adapter for so many watts.
it was the only adapter availibale in local markets . the questions is do you think thats the problem ??

Yesterday I recived my antminer S7 so when I had connected PCI pins i connected the PSU's power cord with that laptop power adapter i said.
Then the antminer powered up with variable fan speed. Then i connected the network cable then when i was going to sit in front of my pc to config the antminer it just powered off and i didn't understand which one powered off first PSU or Antminer but they both had turned off.
i ran and unplug the Power Cord (It was very hat) so that i thought that the pwoer cord may has burned so to test that i connected that to my compuetr psu and my computer didn't powered up so then i knew it that it was burned but 30min after my father test that again and this time my computer powered up .
what is the problem ?? Pleas help
What made Antminer to turn off automatically ??
Have i done anything wrong ?
Someone told me i should have used a 3*1.5mm^2 Power Cord is that the answer ?
