Topic: S7 ASIC Failure (Read 1506 times)
My fans have been set to 80% manually since I first turned them off, so that is not the issue.
You must have missed the posts about this already. Basically it is a known issue that if the internet goes down the fans do not spin fast enough to cool the boards and they will overheat and fail. This is only an issue on earlier batches (not sure which batch it was finally fixed on) and only if you have the fans set to auto and never updated the firmware. There is firmware that fixes this but it has been pretty well established that setting fans to manual above 60% or so will keep this from happening also.
I am in EU, I used priority postage which cost about USD15 and my board came back about a month later by UPS.
Do you remember how long and how much it cost to get the boards back?
Oh yes, I had the same problem, one board was dead. Two chips overheated and desoldered from PCB. The same syptoms like yours S7. Sent back for RMA, received repaired board.
Check to see if its not the power supply, if it isn't send it back for warranty.
3 of my S7 miners have all lost 2 ASIC chains each. This happened about the same time. There was an internet outage earlier yesterday morning. I got them all working and connected again, all 6 of my S7 miners working great. Then about 10 hours later, 3 of mine, the 3 batch 7's I have lost 2 boards each.
I've gone through all of the connectors, everything is seated well. Power supplies have been tested separately, and work fine. They are all running at 625.00M Frequency.

I can send Kernel logs if that would be useful at all.
