Can you mine any other coins besides BTC with the NewPac?

At 4.3GH/s, a 1 diff nonce should appear every second on average.
Scaled to your speed, if enough time passes where 20 of those appear consecutively missing from the asic, a "missing nonces" message will appear.
At that point, the software applies a quick reset on the chip to clear out any lingering issues in an attempt to revive it.
It's essentially the ZOMBIE clearing mechanism kicking in, an additional improvement over the 2Pac.

An occasional one of those at higher frequency could probably be overlooked, if all else looks normal.

Thanks for the explanation.  I now see says the blind man Smiley

I have not been getting too many of them.  Just wanted to understand what they were.

If you run multiple instances of cgminer, you can target each instance to specific miners with the gekko-serial option.

I had seen this message, but thought it was for Windows only.  This is working nicely.  Now need to let it run for some time and see if it is making any difference.

Thanks for the reply, cekolaw.  Congrats on getting to 1TH.  

I am new to mining, but not to tech Smiley  I started at 100GHz (maybe lower with 1 Newpac) and gradually went up to 600 GHz when I had the right setup - an Icone hub that can provide 2.1A to each port and a fan to keep the Newpac's cool.  I placed the hardware in my basement which is 42 deg F.  At 600 Ghz I could still touch the heat sinks.  I have 3 Newpac's on the hub.  Plan to add another 5 soon, once I get things stabilized.

I think there is an issue with my GSH 1 chip.  I am trying to gauge if it is the hub or the Newpac.  When I go above 525GHz, things start to become unstable on GSH 1.  The frequencies start to fluctuate all over the place.  I think there is monitoring on the ASIC that tries to reset it and stabilize the ASIC.  I wanted to know what "missing nonces" meant from a programmers perspective.  Tried to look everywhere.  Could not find anything.  

There was another post in this forum that talked about what the power consumption were for some of the frequencies, very helpful.  At 600GHz, I am at 13.62W (without AutoBoost.  I have AutoBoost turned on).  It would be within limits of the hub.  I have throttled back to 525GHz.  That seems to work best for all 3 Newpac's on the hub.  I was trying to see if I could only set GSH 1 to 525GHz and the others to a higher frequency.

Happy mining...

Can someone explain what the missing nonces mean?

Feb 11 21:37:17 raspsvr1 cgminer[8850]: GSH 1: missing nonces
Feb 11 21:37:17 raspsvr1 cgminer[8850]: GSH 1: Toggling ASIC nRST to reset
Feb 11 21:37:18 raspsvr1 cgminer[8850]: GSH 1: setting frequency to 600.00MHz

I am getting this on one of the Newpac.  I have three running on a powered hub with fan.  The other two does how have this issue.

Also, can I set different frequency for one of the newpac's?
