searched but found nothing about underclocking the sp30. there was only a conversation about underclocking for running it on 110V circuits.
so anybody have any information about underclocking and extending the sp30 lifetime in light of the giant difficulty increases?
Very easy.
Set max-voltage to 0.675 in settings tab for top and bottom.
UPD:
If you want even lower, ssh to station, and edit /etc/mg_custom_mode to something like:
FAN:60 VST:630 VSB:630 VMAX:640 AC_TOP:1300 AC_BOT:1300 DC_AMP:150
Enjoy.
