Raising the Multiplier

Lower the base clock. Before you start increasing your multiplier, you're going to want to lower your base clock a little. This will help make your multiplier increases more precise. Using a lower base clock and a higher multiplier will lead to a more stable system, but a higher base clock with a lower multiplier will lead to more performance. Finding the perfect balance is the goal.

Raise the multiplier. Once you've dropped your base clock a bit, start raising your multiplier in 0.5 increments. The multiplier may be called "CPU Ratio" or something similar. It may be set to "Auto" instead of a number when you first encounter it.
Run a stress test. Reboot your computer and run your bench marking program. If your computer doesn't encounter any errors after a few runs through the benchmark, you're good to raise the multiplier again. Repeat this process each time you increase the multiplier another increment.
Keep an eye on your temperatures. Make sure you pay close attention to your temperature levels during this process. You may hit a temperature limit before your system becomes unstable. If this is the case, you may have reached the limits of your overclocking ability. At this point, you should find the best balance between increasing the base clock and increasing the multiplier.

• While every CPU has a different safe temperature range, the general rule of thumb is to not allow your CPU to reach the 85 °C (185 °F) level.
• Repeat until limit is reached and the computer crashes. You should now have settings that just barely cause your computer to become unstable. As long as your temperatures are still within safe limits, you can start adjusting the voltage levels to allow further increases.
