Im having issues with a pair of SP10 units that im trying to undervolt for efficiency and slow fans.

at 15% fans, 600mv start, 620mv max, and 750W max, i see initial hashrates arounf 900GH/600W but it quickly has 5-10 chip errors per machine ('xxxxxxxxxxxx' all over the place in the stats tab) and drops to around 750GH/500W

am i tuning something wrong? temps seem fine with the slow fans, and the intake/exhaust is about 20/60

edit: seems that a starting voltage of 610mv eliminates the majority of 'dead' chips.

is scheduling available or planned for implementation in the SP10?

No, but it cab done from cron using ssh.
I hope someone from community can prepare a guide that I will publish.

i tried a cronjob with cat /etc/mg_custom_mode_day > /etc/mg_custom_mode && /usr/bin/local/spond-manager restart
and while it changed the mg_custom_mode file, it failed to correctly restart the minergate. any attempts to restart minergate via the ui, ssh, or reboot seemed to not work. same with factory reset (keeping cgminer.conf). a recovery with uSD worked though.

I havent tinkered with an SP10 in some time, so am not sure if what worked fine on the SP3x is a bit different here. not sure if the problems i encountered with minergate failing  to restart are due to a difference in the way the files work. perhaps the next-best solution is either:
cp -rf /etc/mg_custom_mode_day /etc/mg_custom_mode && /usr/bin/local/spond-manager restart
or
cat /etc/mg_custom_mode_day > /etc/mg_custom_mode && reboot
