You usually need to have EIST / SpeedStep enabled in the bios for the Minimum and Maximum processor state to show up in the Control Panel -> Power Options. Some motherboards need EIST enabled for turbo boost to work properly too since the two are related. Once EIST is enabled, disable C1E and set the Minimum to 100% to keep the multi from dropping down at idle if that's what you want to happen.
Thermal throttling is when the multiplier drops down to its minimum which I think is 9.0X for an X3440. Turbo throttling happens when your multiplier starts dropping down to its default value. Turbo boost is dependent on core temperature so somewhere around 80C, some motherboards and CPUs will disable all turbo boost leaving you with a 19X multiplier. Some motherboards let you bypass turbo throttling based on power consumption or core temperature while other boards do not.
