OCCT will report the current CPU Frequency. If you have Intel Speedstep enabled, then OCCT will display the frequency modified by Speedstep.

Speedstep is an intel feature that changes the CPU Multiplier "on the fly" when your CPU is unused, in order to save energy. Your CPU will be downlocked, thus using less power.

The CPU FSB will remain the same, though.

When a test is launched and the CPU is busy (i.e. after a minute in Auto and Custom (fixed) tests, and immediatly after launching a Custom(Infinite) test), the CPU Multiplier will be restored and OCCT should display the real overclock %.

Does this explain your problem ? If not, just tell me what is your setup (CPU, motherboard) and tell me the values OCCT detects (a screenshot is more than enough).
