Unlike CPUs, graphics card overclocking is done mostly via software, so the first thing you should do is make sure you have appropriate drivers for overclocking.
I'm not sure about drivers produced by specific manufacturers, but NVidia reference drivers should work for pretty much all GeForce based cards.
Check out
www.geforcefaq.com for links on where to get the latest drivers. (This site also has a good bit of info on overclocking, so read it carefully) Note that the latest available on NVidia's site (21.41) does not support overclocking. I use 12.60 quite happily.
After you install the new drivers, you have to make a little registry tweak. Details of this are available in the Geforce faq, but most people opt to run a program known as Coolbits to make this registry tweak. Available at
www.tweakfiles.com and a bunch of other places.
After you have the new drivers and performed the registry tweak, you get a little tab in the display properties->settings (depending on the OS you run, this tab may appear in different submenus) that will allow you to overclock. First, you enable overclocking with a check box. Then reboot. Then move the sliders for memory and GPU clock and apply the settings.
FYI: for the GeForce2 MX series, GPU overclocking is pretty useless (but fun for bragging rights) Memory overclocking is where the real benefits are. Like any overclock, move in small increments and test system stability. (Oddly enough, at one setting Quake 3 would run just fine for hours, yet a high-res Winamp vis wouldn't last 3 minutes) You can look at other people's sigs for general neighborhoods. I got 210 GPU / 210 mem with a Hercules 3D Prophet II MX - worth a good 6 fps at 1600x1200x32
