Any ideas on this one. I know you are extremely knowledgeable.I have read and used a couple of your post. Just trying to get stable at 225.

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.

Thanks

Just my piece, but tuning in voltage, for frequency really helped me. Try at 225 Hz 0760 voltage, and try them again, or anywhere from 0.75v-0.76v in 0.005v increments. You can go out of these ranges but one will be the sweet spot for that frequency.

Seeing you seem to be OK powering these up, I concur with tuning in the voltages ...

I will give the voltage tweak a try . Usually takes about 4 hrs to downgrade. Thanks

I seem to find the sweet spot after 15min, then seems to run stable. I'm getting as much as 50GH/s for 0.005v, but there are also sweet spots for each frequency too, which maybe the same voltage for the previous frequency.
