Strategy

Assuming overclocking via a 150-MHz front-side bus rate, a significant portion of Pentium III 667EB chips can effectively scale to 750 MHz. Otherwise, expect overclocking returns under 700 MHz, as this chip still suffers from a low multiplier. One note of interest is the change in Intel's model designation scheme to avoid any public relations fallout from marketing a 666 processor (the biblical "number of the beast").
