Demo different configurations on PowerForce and ZForce cards. Switch Demo is an easy way to try out switch settings on a card. It was developed by and for technical support reps at PowerLogix to assist in support issues. If you are trying out different settings to optimize bus speed or overclock a processor, it may help you verify your settings. Simply click on the switches to toggle positions. Bus speed, bus ratio and processor speed settings will adjust automatically. If you choose an invalid ratio setting, it will report 0MHz. Remember that 10x and 9x ratios are not supported on all cards. To see a full chart of settings, like the one in the manual, click on the chart button. This program will not adjust the settings on your card. It is merely for demonstration.
