Dual processing systems can help split the CPU load over two CPUs, thus allowing for better performance. But just because you have two processors doesn't mean that your system is set up correctly to handle them, and programs may need to have a preference enabled in order to "see" both processors.
To make sure Windows XP recognizes that you're using dual processors:
1. Open the Task Manager by hitting Ctrl-Alt-Del.
2. Click on the Performance tab. You should see two graphs under "CPU usage History."
3. If you do not see two graphs, there are three possible reasons:
Windows can show you the activity happening with both processors in a dual CPU system.
Although most software will work with dual processing systems, some won't, and it may be necessary to disable mulitprocessing. Here's how to do this with Cubase SX 3.1.
In Cubase SX, you can decide whether to use multiprocessing or not.
5. Click on OK, click on OK again for the Device Setup window, and you're done.
Enabling/Disabling Dual Processing in Sonar
Sonar is another program where you can specify a multiprocessing engine. Here's how to do this with Sonar 5.
Sonar's Multiprocessing option is found in the Audio Options section, under the Advanced tab.
4. Click on OK to exit the Audio Options window -- done.
