Antminer S9 stops mining

[jeannap23]

Anyone else have issues where there's nothing wrong with the miner it just stops mining and you have to reboot? Because of this my payout keeps getting delayed another day.

I have one S9 that stops mining completely and hasnt mined for a couple of days now. I am going to try a new power supply. (I currently use HP1200w platinum power supplies, I am going to source a bitmain psu and give that a shot). It worked fine for 24 hours, now doesnt mine at all.

Thanks I might try that. I have an extra power supply. I'll try switching them and see if that helps. It's still running when it's not hashing which is why I didn't think about a new power supply.

Try a better ETH cable.

Will cat 6 cut it or no? I am having the same problems as this person with only two machines out of 25. Could the cat6 be the culprit?

CAT6 is fine.

I have managed over 20k total miners in my career and they have all used CAT5 cabling. If switching to CAT7 solved your issue it was only because the CAT5 cable was damaged. There is no good reason to go buy a more expensive cable when CAT5 works just fine and no reason to tell others to spend money on something they dont really need.

Yep. Unless there is a lot of some kind of interference or very very long distance for the cabling, which both are quite rare cases,
Cat 5 patch cables will do the job just fine.
