You can confirm this by noting the 15C default temperature reading.
If you paste your kernel log here, it will help us to narrow down your issue. Title: Re: hashrate one hashboard is 800 g/h and temp is 15 Post by: BitMaxz on October 03, 2018, 10:42:08 PM Did you try to replace the hashboard cable or swap the cable to other hashboard? Do this first then make sure the socket is clean before you place the cable. Another possible cause is PSU, it might give low power to one of your hashboard, if you have a multitester you can check the PSU if the given power is 12v, then it's fine if not then your PSU is your problem.
Anyway, you can follow this troubleshooting guide from here Possible problems and solutions for S7, S9 (fixed frequency) & L3+ (https://support.bitmain.com/hc/en-us/articles/220872007-Possible-problems-for-Antminer-Troubleshooting-for-S7-S9-L3-) Title: Re: hashrate one hashboard is 800 g/h and temp is 15 Post by: big.miner on October 04, 2018, 01:52:50 PM Did you try to replace the hashboard cable or swap the cable to other hashboard?
