After acceleration in global overdrive I have ceased to reset memory clock, so now also shows the maximum frequency 1450 mhz in aida64 or gpu-z programs. Reset programs global overdrive or MSI Afterburner is not helps . And the slider in the global overdrive why it is blocked . Help please !
The problem was solved creating a second profile with the standard frequencies in the MSI Afterburner and pereklcheniem between them. Slider unlocked in the global overdrive.
