hwinfo64 IA: Max Turbo Limit + IA: Turbo Attenuation (MCT). What do they mean?

[ShwaBdudle]

I've been scrolling through HWINFO64 and the info that it shows there, and I have noticed that (Yesterday) The "IA: Max Turbo Limit" Was "Current: Yes, Minimum: Yes, Maximum: Yes" and the "IA: Turbo Attenuation (MCT)" Was "Current: Yes, Minimum: No, Maximum: Yes". Currently, Everything on both of those "Settings" is set to Yes.
What do they mean? and is this normal and Safe for the CPU?
