Overclocking a locked multiplier CPU (i5 3470)

Hey people :)

I wonder if I could OC my i5 3470.
My rig isn't built for OC so I have a few questions regarding that issue.

CPU: Intel i5 3470 3.2GHz (stock)
Motherboard: Gigabyte B75M-D3H
CPU Cooling: Zalman CNPS5X SI Edition
PSU: SeaSonic X-660W
Case: Fractal Design Define R4 (+1 140mm fan added in the front)

1) How far can I push my CPU? (if I even can..)
2) Will it be noticeable in extracting / converting movies (which I do a lot) / overall use?

Thank you,
Omga4000 :)

    You can multiplier overclock that CPU by 4 bins (400 MHz), but only with a Z75 or Z77 motherboard. There's also BCLK overclocking, but that's not going to get you very far and overclocks other parts of the system that really don't respond well to overclocking.
  2. Overclocking the i5 is possible on only selected few H77/H75 motherboards without increasing the Bclk (Base Clocks).. These motherboards increase the turbo frequency and force the processor to run at the turbo frequency all the time... quite neatly done :)
    Intel not good y u lock down the multiplier?
