Since upgrading from 10.6 to 11.3 (and now 11.4) my hawaii rigs are having hash rate drops every so often. About 5-7% drop lasting for around 2 minutes before going back to normal for about 10-15 minutes before it happens again. Any idea what might be going on?
Confirmed same issue with an rx390 (Hawaii)
Maybe this:
This sounds like a temperature issue.
Your GPU reaches a certain temp.
Miner reduces intensity so the temp can come down.
Once temp lowers GPU intensity goes up again.
Over and over.
These are settings in the config file.
Or. It's something else.
It's definitely not a temperature issue on my rig. The card runs at a constant 71 degC
i didn't necessary mean your rig was running hot.
It was this setting.
-ttli reduce entire mining intensity (for all coins) automatically if GPU temperature is above specified value. For example, "-ttli 80" reduces mining intensity if GPU temperature is above 80C.
You can see if intensity was reduced in detailed statistics ("s" key).
You can also specify values for every card, for example "-ttli 80,85,80". You also should specify non-zero value for "-tt" option to enable this option.
It is a good idea to set "-ttli" value higher than "-tt" value by 3-5C.
If you had that set to 71 or below it would cause a similar issue.
Anyway. Good luck. Hope you find the issue.
