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?
On what pool are you on.. I use multipool with 796 clock and the hash rate is stable now for about 1 month on 4,5 mhz per mld.. using aprox. 2 amps per mld.
The only way to know what is happening is to measure volts and amps to know what the real problem is
Use a usb measuring device they are on eBay or Ali for 3 bucks..
Good luck...
