I've been having trouble with the miner's reliability...
So far, I haven't been able to keep it going for more than 4 hours.
In this forum the two explanations I've been able to gather are that either the power supply is too low, or the memory voltage is too low. I'm fairly sure the power is enough, because the miner starts (correct me if that is a wrong conclusion), and even though I've tinkered with the memory voltage it doesn't seem to make a difference. Not only does it not last, but it doesn't last in an unpredictable way - it can last anywhere from 30mins to 4hrs.
Any help would be much appreciated!

The power supplied to these miners is a very big part of their proper operation.
I run 5 moonlander 2's at around 5Mh each (freq=876, d-1024) and they are taking around 12 watts per.

They would not run on a TRIPLITE 10 port hub due to the circuit board copper power lines not being able
to supply the current required to make them hash at 5Mh. I had to crack open the USB hub and solder wires
along the power paths to the USB ports and remove the power jack and create direct wired connection to the hub.

The power draw will increase as your Mh increases via the Freq set in your .bat file.
Also if you tun up the Mem/Core voltage you power demands will increase.
5Mh each at 12 watts is 2.4 amps per unit or 12 amps @5vdc total draw with 5 units!
Make sure you have enough power to all the Moonlander 2's to work properly.

Try turning down your freq settings to 600 or less and see if you can get them all hashing at lower Mh.
If so then increase the freq step by step until they fail/reset. the setting below is your max freq unless
you supply more power (amps) to the hub. I have not had too many issues with reliability.

Also make sure you download the latest miner software with the auto reset feature.

Thanks for the help - but now you mention it, there is something else that seems a bit odd. I installed the latest driver with the auto-restart feature, although hat hasn't come into play when my miner stops. Any thoughts on that?
