Start by pressing the "del" key when booting up to get into your bios. In the "frequency/voltage control" section, change your cpu fsb from 133 to 138, save and exit. Your system should run stable at the higher speed with no other adjustments. Then if you like, try changing the memory timings in the "advanced chipset features" section under "advanced ddram control". If your board has spd or manual settings, change to manual, and enable "4 bank interleaving" if you can, and change from case 2.5 to case 2, and see how stable it runs. If using more than one stick of ddram, be sure to set the "ddram command rate" to 2 or auto. Sometimes it won't even boot up with 2 sticks when this setting is at 1T. If you have a section for agp settings, be sure to enable "fast writes", "sideband address", and "prefetch caching". For even higher clock speeds, you will have to raise your cpu voltage to 1.85-1.9 and memory at +.2 volts. Monitor your cpu temps using a program such as "motherboard monitor 5". If your cpu temps rise above 57 celcius or the system is unstable, back off the voltage increases. A good copper heatsink will help your chances of higher overclocks.
