I updated my other post to be more specific.
I figured its down to the chips. No big deal.
... it'll display a chip health thing sorta like in the Antminer webconfig and you can see if one of them is throwing fits.
The miner in question is actually having the fewest rejects and hardware errors of the four. Weird. If there is anything else that I can provide you just let me know.
Like I said, its not a huge deal for me, I just wanted to scratch my mining itch and these are the best for that.
