What command can I use to reset the >memory< clocks to normal plz? thx ? I know there is one for core clocks. 
I try not to adjust these values in the miner, because they do not always work correctly.
In Windows, you can use third-party programs to fine-tune the memory (AMD-OverdriveNTool), and if you need to set default settings, then MSIAfterburner will do. In Hive OS and analogues, this is configured in the application interface
I should have said after I stop the mining app. because the clocks stay as set by the mining app. and afterburner won't charge them ether. But found out I can use the GUI in the unzipped app. to reset the clocks.
