Hey guys!
I've some questions and I hope someone can give me an answer and help me.
My Antminer S3+ is beeing powered with a Corsair RM850 and working 218@stock voltage whitch gives me an avg 440 (0% HW errors). I tried some new settings like 225 and 250 but i got some HW errors (0.043%) and the same hash rates that i got at 218.
I tried different firmwares and kano's cgminer but i got the same results.
Does someone have a possible explanation for this?
(maybe a batch 1?)
Best regards
btw: kano's cgminer sometimes reports 700+GH/s, is this normal?
I would check the voltage at the Miner's PCI-e plug. Some S3's are simply icky, they dont clock well, but either way, the reason why you can not bring it to 500 is its not getting the voltage it wants.
Some are better than other as in they can go higher with the same stock voltage. But some PSU's voltage output drop under load, which worsen the condition.
(btw) Also yes, variance is normal.
