More like these days everything is already clocked hard by default. There's basically no point overclocking modern unlocked chips, they are already clocked to 90% of their max speed. Compare that to the above example with 600 vs 900 Mhz (50%! faster)
Some locked chips are clocked pretty slow, but that's normal segmentation :(
