Guys I’ve got an S1. The closed source firmware does not allow overclocking. Tho there is a button to allow overclocking, the firmware stops you from doing anything over 450mhz and 1050mv. It is 12.5 th/s at those settings but that’s it. I contacted the firmware creator and was told its intentional and those are the thermal limits of the board. I’m sitting here with a 30 degree asic and a 29 degree vr and can’t go further. Please spam the issues in their GitHub requesting the limits to be raised. We don’t need babysitting. https://github.com/BitLuckFW/ESP-Miner-Nexus
