/proc/cpuinfo and i7z report different CPU frenquency

I'm using a ThinkPad X201 laptop with a Core i5-520M processor. When I run something like 'ssh-keygen -b 16384 -f /tmp/ssh' to maximize my CPU load, /proc/cpuinfo reports I'm running at 2.4GHz, which is the frenquency without turbo. However, I run i7z at the same time, and i7z reports the processor is running at a higher frenquency at 2.9GHz maximum. More than this, when I run 'lscpu',  'CPU max MHz' is 2400.0000. What's wrong with it?
