I believe you still need a custom kernel that supports overclocking. For the Nexus One, most kernels are 998MHz and there are a few that overclock to 1.113GHz or 1.2GHz, and you need something like SetCPU or Overclock Widget to make the phone recognize those overclocked speeds.

I'm running an OCed kernel on my Nexus One, but I don't have any app installed to change the clock speed. I haven't tried Overclock Widget, but whenever I try SetCPU, my battery life always seems to be worse, even if I limit the max to 998MHz. I'm just running this kernel because its one of the most stable ones out there.

So until someone starts making OCed kernels for the Evo, I wouldn't use one of these apps to OC until you have a kernel that supports it.
