Sounds like the DAG size issue (and probably nothing to do with you trying to tune the GPU, or PhoenixMiner).
If you are using the latest AMD drivers, do the following things:
1. Open AMD Radeon Settings
2. Click the first button in the top left corner ("Gaming"), then click "Global Settings", which will appear at the same corner
3. In the "Global settings", find the setting "GPU Workload" and switch it to "Compute"
4. Radeon Settings will restart and then the problem should go away
Keep in mind that sometimes this setting changes by itself (for example if you remove or add a GPU), so if the hashrate consistently (i.e. not only for a moment) drops to 18-20 MH for 570/580, this is the most likely reason.
