How to make the CPU not change the speed (clock)?

I want to compare execution time of some programs and need constant CPU performance (not necessarily high performance).

The CPU in question is i7-2640M, OS is Windows 7 64 bit.

(google finds only answers to how to repair ("fix") CPU speed or increase it, due to (my) english... is there a word that means "fix - make stable" and is used often?)

From Power Management. First of all, you choose High performance plan.

Select Change Advanced Power Settings and make sure that the marked values are 100%.

There may also be a similar BIOS setting!
