@ Henydiah, The op said that he wants the clock speed to be lower on idle, so disabling Intel EIST WILL keep the high clock
Therefore, @M3 power, leave intel eist ON, and btw, windows 7 will not decrease clock speeds on idle if power plan is set to high performance, therefore set PW to balanced mode.
