I had overclock my GPU, Palit Jetstream GTX 970 (w/o changing the voltage) but after sometimes, the figure will return back to normal.
This isn't the 1st time anyway because i also had overclock my old Gigabyte ATI 5770 and the problem is the same.
I need to reapply the overclock figure using MSI burner.
Anyone know what's actually the real issue? How i can sticking up the overclock mode w/o need to change it everytime it turn back to normal.
