Title: Antminer S7 negative hardware error rate?
Post by: Gren on February 21, 2016, 07:51:09 AM
I have seen a lot of weird stats screen on malfunctioning Antminers :D, but i have never seen a negative value on hardware errors
Rebooted it just because it weirded me out, all is normal now.

Has anyone seen this before? This is a batch 9 S7. What the heck does it mean  ??? this is the second time it has happened to me.

Yeah normal little math bug when the runtime gets too high, it goes a bit derp. You could restart it every week if you wanted but regardless its purely a display bug with the UI.

It seems to happen around 20+ day mark.  Something internal is off with the equation if you have low HW errors and run it for around a month... it ends up being negative.  I first posted it with my S5+ (first one I ran for those long times).   And it could be counted on hitting it before a month each time.

So not really a big deal.  It does make the equation seem a little shady to have negative as a possibility.  But with a miner that runs for a month without issue it's honestly hard to be mad.

Not the first time i see this.

As Notlist3d said, there is nothing to worry about!

Happy mining! ;D

The only thing I would love to see if anyone ever finds it is what exactley what the equation does that get's to negative.   It does not hurt anything at all as far as hashing but it would make sense if that equation with errors is making it look better on HW errors then it really does. 

But not sure as it does seem to heavily be related to amount of day's.   And again it's hard to get to mad when a miner runs for a month that is normally a pretty happy thing.

 I had the error after 31 days.
