Title: ADVICE - One board on S7 shows zero as temp and HIGH HW errors ??? Post by: bilabonic on December 29, 2016, 12:16:02 PM Hi All
All of a sudden my S7 has developed a problem as in pic below....It will run for 30 mins or so then it starts 'beeping' and stops mining and the temp shows 100 !!! Anyone got any ideas ? What board is it (i think it is the furthest from the ethernet port) ?? ALSO is it ok just to power one or two of the 3 inputs on the faulty board ?? I have tried various psu's and still get the same and each PSU powers ALL boards...as obvious. http://img.photobucket.com/albums/v662/romanski/antimer%20faulty_zpsqawnukw5.jpg (http://smg.photobucket.com/user/romanski/media/antimer%20faulty_zpsqawnukw5.jpg.html) Cheers Title: Re: ADVICE - One board on S7 shows zero as temp and HIGH HW errors ??? Post by: not.you on December 29, 2016, 01:31:30 PM Had that exact issue with one of mine. Eventually I could not get it to mine at all with that board connected because it always showed a random temp above 90 (usually like above 110-130) which prevents it from mining. I sent it to Denver for repair. Cost $75 for repair plus something like $25 for shipping.
This is the place that can do repairs: bitmainwarranty.com But looking at the site: https://bitmainwarranty.com/shop/ I see that they have S7 boards for sale directly so you may want to just go that route. Why the 45 chip board costs more than the 54 chip board I do not know (maybe because it runs at a higher freq?). Title: Re: ADVICE - One board on S7 shows zero as temp and HIGH HW errors ???

It is ok to run just 1 or 2 boards. You just have to disconnect the power and data cable of the faulty board. Title: Re: ADVICE - One board on S7 shows zero as temp and HIGH HW errors ???

Cheers, so what i thought was correct then, board one is basically opposite to the PCIE supply for the control board.. What i also asked is it possible to run one or two of the inputs (out of the 3) on the faulty board ? Title: Re: ADVICE - One board on S7 shows zero as temp and HIGH HW errors ??? Post by: isoneguy on December 30, 2016, 12:37:30 AM Yeah, don't tell anybody this but you don't have to supply power to all 3 pcie plugs. If you are running a full s7 at full clock speed then I wouldn't use less than 2 of the plugs per board.
It will run power to the entire board though...even with 1 plug. I have one running with 1 plug per board. It's underclocked mind you... 1 pci-e plug won't be throwing more than 300 watts...you don't want all that power going over a single wire/connector.

Post by: IITravel01 on January 18, 2018, 08:23:58 PM So, I've got a S7-LN that started doing this, temp. on one board is near 90 while the other is in the 30's, all 45 ASICs appear to be working on both boards. Mines for a while, then lots of HW errors and beeping which then stops mining. Is this something that can be fixed?
