I think that you are not pressing the correct buttons Look at the bottom of the following web page.

The i5 750 has a locked multiplier, so you can't overclock by changing the multiplier. The only LGA 1156 chips that had an unlocked multiplier were the i5 655k and the i7 875k.

You can overclock the chip, but you have to do it by modifying the BCLK settings. You can find a complete guide to overclocking Lynnfield and Clarkdale CPUs here.
