I have 4 x S3 antminers . I had the 10/24 firmware on them seems like MY GHS was dropping from 450 to 340+ but never going back up to 450 or even close any ideas. When I reboot the GHS jumps back up for about 10-12HRs then back down again. All set at s3+ default 225. I changed the voltage to 0770. I just installed Doges firmware on one of them to try it. Any one has any ideas it would be greatly appreciated. Thanks in advance.
do what i did, go to "scheduled tasks" and input this
0 */4 * * * /sbin/reboot
this reboots ur miners every 4 hours or u can select whatever amount to put in, i found they lasted 4 hours and then required a kick in the ass to get the ghs back up there.
