I'm curious which vendor documentation you're working with here. >From the spec, 0 = normal 1 = overboost 2 = silent Also you can use DSTS on the 0x00110018 device to check the exact capabilities supported, which you should use to refine which modes can be cycled through. Bit 0 = overboost supported Bit 1 = silent supported Thanks Daniel
