Title: Antminer S5 reliability and losses from defective miners Post by: RussianMiner on July 27, 2015, 12:39:52 AM Dear miners with big Antminer S5 farms,
I want to calculate approximate losses from my mine from defective S5 miners Could you be so kind to tell us what % of your Antminer S5 become defective and stopped working after you started your mine? Have you tried to repair them somehow? best regards, Sander Title: Re: Antminer S5 reliability and losses from defective miners Post by: Philipma1957onvacation on July 27, 2015, 12:48:05 AM Dear miners with big Antminer S5 farms, I want to calculate approximate losses from my mine from defective S5 miners Could you be so kind to tell us what % of your Antminer S5 become defective and stopped working after you started your mine? Have you tried to repair them somehow? best regards, Sander I did a survey of sp20 owners loss rate is 4-7 percent. I may do an s-5 survey but think that 5 percent is a safe guess for a six month time period. Note the sp20 survey was done from my main account philipma1957.

Wow! 5% loss is quite painful if it's true! Does anybody have actual numbers about S5?

More then three hundred machines .
I had thirteen all of mine worked well. Low clocks good power supplies. I think five percent is pretty close plus 1 or minus 1 for the sp20. as for the s 5 no survey. I do think the s-3 was really good maybe two or three percent but the s-5 does seem a bit worse then the s-3.

2 of them has problems with boards. 1 of them is unaccessible. 2 of them is running, but not hashing. Beside this I had 1 notworjing fan. I also have 40 S4. 5 of them has burnt PSU.Many (more then 10) not working fans. Action:Bitmain sent PSUs without any cost for S4s.For S5 , I have sent a board and we have been writing to Bitmain for control board and not working board.I will send you a feed back about my customer experience and their attitude as soon as we have conclusion. I used to have (I do not for the moment) 20 pcs of SP20.I have run them for 6 months without any problem.
