Just like the title.  I've tried factory reset, re entering the pool info, etc. No go.  Would like to have this running before I head out tonight. Sad

Have you looked at the "ASIC Stats" page to see if there are any errors coming up or anything unsual?

It looks like it loaded the Dawson SP10 firmware because that's what it shows on the main screen now.

After a recovery, everything is back in order.  Looks like a PSU problem of the paper clip method not secure enough to keep the PSU stable.

That's interesting. Was the unit resetting? The PS_ON signal is just a TTL level, it's weird that if it worked a little but not at high power levels.

I was using 2 HX850 psus.  I think one of the wires on the 24pin adapter is loose. I even tried one of the antminer switches and that's where it really showed up as the led would come on and then go off with just the slightest movement. I put it on a different psu and it's been rock solid ever since.

Edit:  Yes the unit was probably resetting since it wasn't hashing above 500gh/s.  But by the time I would notice, it wasn't hashing at all.
