Hi, i have a problem with a miner: it only shows the temp of two boards, the central one is NOT showed. What can i do to fix this??
Thanks!!
If it's mining fine, do nothing. You have a bad a temp sensor I guess. I wouldn't be too worried since you have two good sensors ... the unit will detect if it is overheating or not. EDIT: missing words ...

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

I have asked before with bitmain and as long as you have a good sensor they say you should be good. This goes all the way back to S3 day's they were happy if just one was working, so in your case with 2 you should be fine as even if another failed still have one. You only really need one for it to shutdown if it get's to hot. But I know the feeling getting a new one and seeing one dead my first time I got that I thought was something to worry and it's not. Your MUCH better off running it then going weeks possibly without a hashing board for a temp sensor (and I don't think they would take a RMA for just temp sensor anyways).

I own 11 pcs of S7 discount coupons.I want to donate them to someone who needs.To help as many as possible I will donate 1 coupon per account.
I could use one of these if you are still offering. Cheers.

i'm using an evga 1300w ps, maybe the new one fan units require all 3 power plugs to be populated? tried all three in one board to no avail
definitely try to get more power for that unit, you may not have enough stable power to allow the boards to hash. use the 1300watt for 2 boards, and then another power supply to power 1 board and the module.

You only really need one for it to shutdown if it get's to hot. But I know the feeling getting a new one and seeing one dead my first time I got that I thought was something to worry and it's not. Your MUCH better off running it then going weeks possibly without a hashing board for a temp sensor (and I don't think they would take a RMA for just temp sensor anyways). I have a machine that has a board that often reports a zero temp but occasionally it reports some random temp, I have seen numbers from the 30's to 140's. What sucks is that the miner will not mine if the temp is reported above 90. If you turn off the checkmark to stop mining above 80 it will indeed mine with a temp between 80 and 90 but there does not appear to be any way to make it mine with a temp reported above 90. I have poked around in the file system and can't find anything to disable that. So when it reports a temp above 90 all I can do is power cycle it over and over again until it reports a temp below that. It usually runs for days without that erroneous temp changing (whatever it is) but every so often it just changes, and if it randomly changes to something above 90 it stops mining. I don't have a way to remotely power cycle it either so sometimes I have to get in the car and drive down to the miner's location and power cycle it over and over to get it back up and working. I am thoroughly unimpressed with the S7's both in terms of the price (including the drastic price drops) and the quality. These look likely to be the first miners I have bought since Butterfly fucking labs that will not even break even.

my 3 b1 S7 miners goes to silence yesterday, they can reachable but dont hashing, cgminer cant start hashing. i tried nearly everything 1 solution is flash new firmware and go. but i am using 6hashboards latest version is not handle 6 hashboards. I suspect for date settings with ntpd . like a timebomb. change date settings to 2015 not works. any ideas ? i am not linux guy i cant figured out.

Are you saying you had 3 miners all stop working at the same time? If so that doesn't sound like a problem with the miners, it sounds like a network problem. Do you have backup pools configured? Do the pools show alive or dead?

I suspect for date settings with ntpd . like a timebomb. change date settings to 2015 not works. any ideas ? i am not linux guy i cant figured out. I had the same problem today and some days in the past also. When you start or restart cgminer the cgminer.sh script (/etc/init.d/cgminer.sh) checks that the connectivity to 114.114.114.114 is up. I guess it is a one of bitmain ip. Today this IP ( 114.114.114.114) is down, so all of Bitmain gear (S3, S4, S5, and S7) will refuse to restart cgminer if you restart the miner or change your configuration. If 114.114.114.114 is not up, the cgminer.sh script exits and does not start cgminer. To fix the problem there are 3 possibilities: 1) Wait for 114.114.114.114 to get back up => Seems unacceptable to me. 2) Upgrade the firmware to a newer version 3) Fix the script and restart cgminer.sh To do that : 3.1)Connect to your miner by ssh Replace 192.168.0.170 with the IP of your miner 3.2)Edit /etc/init.d/cgminer.sh and comment out 3 lines from line 35 to 37: vi /etc/init.d/cgminer.sh #if [ $network_ok -eq 0 ];then # return #fi If you don't know how to use vi : http://www.tutorialspoint.com/unix/unix-vi-editor.htm3.3) Then restart cgminer with : /etc/init.d/cgminer.sh restart Warning :You will have to redo the same modification if you reboot ! To avoid that, do after fixing cgminer.sh: cp /etc/init.d/cgminer.sh /config/cgminer_fix.sh And then if you reboot you only need to do : cp /config/cgminer_fix.sh /etc/init.d/cgminer.sh /etc/init.d/cgminer.sh restart

I restarted both of my S5's a couple of hours ago without issue. 114.114.114.114 is apparently a DNS server in china. It may indeed be down since it is not responding to DNS queries from me but I am on the outside of the great firewall so maybe that is normal? I have all of my miners set with static IP's and 8.8.8.8 for DNS.

I have all of my miners set with static IP's and 8.8.8.8 for DNS.
The exact original code in cgminer.sh is network_ok=`ping -c 1 114.114.114.114 | grep " 0% packet loss" | wc -l` if [ $network_ok -eq 0 ];then return fi
So without a doubt, if the miner can't ping it, it won't start cgminer, it does not depend on which DNS you use. Maybe the S5 doesn't use the same IP, but I thought it would. (I have had the problem with S5 in the past but I don't have S5 to check anymore)

This is what I see in my S5. do_start() { # gpio1_16 = 48 = net check LED if [ ! -e /sys/class/gpio/gpio48 ]; then echo 48 > /sys/class/gpio/export fi echo low > /sys/class/gpio/gpio48/direction
gateway=$(route -n | grep 'UG[ \t]' | awk '{print $2}') if [ x"" == x"$gateway" ]; then gateway="192.168.1.1" fi if [ "`ping -w 1 -c 1 $gateway | grep "100%" >/dev/null`" ]; then prs=1 echo "$gateway is Not reachable" else prs=0 echo "$gateway is reachable" fi #ping $gateway -W1 -c1 & > /dev/null #prs=$? if [ $prs = "0" ]; then echo heartbeat > /sys/class/leds/beaglebone:green:usr3/trigger echo 1 > /sys/class/gpio/gpio48/value else echo none > /sys/class/leds/beaglebone:green:usr3/trigger return fi sleep 5s
..and so on... Looks like it only checks for the gateway. I'll check out an S7 in a second.
