Hi again - it's the guy with the half-hashrate MLD. I think my original post has been a bit lost, so I wanted to start again here (I know that sounds really selfish, although I really need to get this miner working again). This is how the conversation went so far:

It used to be hovering around 4.2 - 4.8 although now is around 2.3... any ideas?

Has anything changed in your setup? Low hash rate is usually because you don't provide enough power to device (added another USB device?) or the device is overheating. You need better cooling or turn down the frequency. What happens when you unplug for 5 minutes... does hash rate go back up?
Nothing has changed... I tried unplugging it and rebooting the whole thing - nothing. The power was working fin before, and nothing has changed, so I can't think what it would be...

Thats normal, especially if its been running straight for a really long time. Some cores will destabilize and shutdown eventually. Driver has a fix for a complete core stall, but not drop in hashrate yet. Will have this fix in on the next release.

And just to be clear - the cores can come back online right?

yes, but you will need to manually restart it currently.

Hmmm...
The restart hasn't worked - it's just stayed around that same 2.7. And the odd thing is, the miner hasn't actually been running straight ever for that long. I always give it a 5 min break every day (used to be twice a day) in fear of it overheating (I know it's stupid, but just a paranoia). Is there any other possible explanation?

Any thoughts?

Thanks - the MLD support has been the best for any product I have EVER bought... ever. Full stop. Thanks for being so on the ball!

My miner has been working just fine now for about 2 months now, although in the past few days its been acting really weird... the hashing rate just dropped by about half. It used to be hovering around 4.2 - 4.8 although now is around 2.3... any ideas?

Thinking about it, I'm not sure if the new driver I've been trying to download is the new one. I've been doing it through my RPi's terminal, and both the new driver and old are named the exact same thing... so maybe it has just been downloading the same thing over and over again? Any ideas on how to specify the new driver?

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?
