Overclocking voids the warranty? Then why is it a drop down option in the control panel of your software which ships with the units.
Secondly; why is it not listed on that submenu (Advanced) as WARNING saying that clocking above 350 will void ones warranty.
Antminer warranty is like dog shit in the street.
Antminer dont have any warranty.only warranty is he first take money for miner and delivery usually used miner.
i have recive one s1 miner whit totally broken fan mount,he sey bay one in localy shop. next time you bay s-1 i send you replacement because post is exspensive i bay more 7x s1 and never receive this broken fan.
I'll have to say I havent had that experience. I ordered roughly 50 of the S3+ units - and only one was defective - just a bad fan - it happens. They were super responsive and helped me get it swapped out.
As far as the S5 units - the ones I received (24 of them) - they were definitely used. There was a lot of dust build up on the fan blades - you could tell these had been run for some time.
HOWEVER - I think it goes without saying that when you buy a miner from Bitmain or any miner manufacturer - they are first used to mine then sold as they roll in their newest generation miners for themselves. Their business model depends on that.
I would have liked the units I received to not have so much dust build up. But all 24 of them are working just as they were promised - even better. And I replaced the fans anyways.
My only issue is Dogie; he was helpful with the wiring diagram for using two PSUs with 3 miners; but more often then not he seems misinformed on a lot of different topics. I am not even 100% convinced he actually works for Bitmain or just self appointed himself. But that's a whole other issue.
So for me Bitmain has been great. Just wanted to throw in my experience there.
