Sure is strange how that helps but it does. My controller that I thought was bad I got it to boot eventually using an sd card. Then I let it mine for 2 weeks and the controller seems to be good again. Sometimes it glitches and I do an SD Boot or recovery and it is then good again. If I could just get the loop 3 to come up again I'd be a happy camper but I cant. So for now my sp20 mines at 1-1.1TH and is pulling about 670 watts. I used the command vi /etc/mg_max_asic_temp and entered 7 to set the max temp to 120c instead of 125c and I am getting much better/stable results.
Using Putty/SSH I log into my miner and enter
vi /etc/mg_custom_mode.
I then hit the insert button which allows me to edit the configuration. Right below is what I am using for my settings:
FAN:05 VS0:700 VS1:700 VS2:700 VS3:700 VMAX:710 AC0:288 AC1:288 AC2:288 AC3:288 DC_AMP:170
I then hit the esc button. Then I enter :wq and hit enter to save the config. Then I hit restart minergate on the web gui to have the changes to take effect. Below is a screenshot of the results when looking at the ASIC Stats on the miners web gui. I chose the fan to be at speed of 05 because if I have it any higher it starts a fight with me and my wife.

looks cool do you think it will help my miner are you in the uk?
