I already solved my problem. one of my hashboard temp. goes upto 85 c . then after cleaning my hashboard i changed my over temp. hashboard in to the middle position. Now my maximum temp. comes upto 80-81 c. and miner working good from last 3-4 days.
That is what I told him if he can able to reduce or cool down the temp a bit the miner can mine at high-performance mode.
That's the only reason why it automatically drops in hashrate is due to overheating one easy solution is to clean all dust from hashboard and both fans or improve the fan speed.
If you don't know how to improve or increase the fan speed you can manually send this command below with the FMS app under diagnose.
[{"command":"ascset","parameter":"0,fan-spd,100"}]
The 100 from that command is the speed of 100% you can change it to lower than that if you want a bit slower.
I'm sorry I haven't replied for a long time. But my son was born and there was no time.
The problem still continues.
Why don't I think it's the temperature?
My friend also has 2x avalon 1246 85T.Bought at the same time from the same dealer and has always behaved the same as my avalon.
His avalon works at high performance mode at hash board temperatures above 85 C.It worked the same for me.
I am attaching the last log. Temperatures are low.But THs is still 72.6.
I noticed that when the normal mod is on, the temperatures are lower. When I switch to high performance, the temperatures rise a bit. (as in the log) This is normal. Higher performance means higher temperature. But the power is still 72.6 THs.I think that the asic works at high performance, but I don't know why it gives less THs.
If the power was reduced, the temperature would also be reduced. Am I understanding this correctly?
I can also insert a screen from the asic website. Where are the temperatures:
27°C(T)
75°C(H0)
75°C(H1)
76°C(H2)
