    Ive been using RM Clock 2.1 for awhile but was wondering a few things:

    1. What is a p-state and should i use them?
    2. With the p-state box there is an index button to check, what is that for?
    3. Should I use throttleing or let the cpu do it on its own?

    Thanks in advance

    The CPU has a bunch of low-power states.

    There are S-states, T-states and P-states. The tricky part is in remembering which is which... ;)

    I think it works like this:
    S-states simply reduce the power consumption of the CPU when idling, without changing clock speed, voltage or anything else. It just idles a bit. (I think the S is for Sleep)
    T-states throttle the clock speed down. Intel's Speedstep and AMD's PowerNow/Cool & Quiet does this. (T for Throttle)
    P-states work by reducing the voltage when the CPU isn't in use. This is typically the most efficient way of reducing power consumption, so yes, it should be used when possible. (P could be for Power)
