I found the solution,
edit the msiafterburner.cfg file and replace the two lines:
UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode = 2
Isn't this mainly for OVERclocking the card beyond "safe limits"? Why should UNDERclocking be limitted?edit the msiafterburner.cfg file and replace the two lines:
