Alright, this is where reading patch notes is super important. Before the latest HiveOS update, there was a “bug” with T-Rex and HiveOS in which it wouldn’t show the red circle within the HiveOS page. This didn’t mean that you weren’t getting invalid or rejected shares, it just meant that HiveOS wasn’t showing them. The latest HiveOS patch “fixed” this bug and now T-Rex miner and HiveOS will properly show rejected/invalid shares.
You will never have 100% accepted rate, it just won’t happen. This is why looking at the farm efficiency is so important. Running for months on end, you should be around 99% efficiency. If you’re at that, you’re good.
You can login to your server and run the command “motd watch” without the quotes. This will show you what T-Rex miner is doing and the accepted/rejected share ratio of each card.
Again, there isn’t anything wrong with your cards and they didn’t “suddenly” become unstabble. HiveOS just started reporting them properly.
For reference…
