与显卡相比，声卡占用的系统资源要少很多，但通过合理设置仍会节省一些系统资源。比如在Windows环境中关闭“音量控制”中的StoreWide或3D Depth两个选项，会大大减少声卡的CPU占用率，一般Windows的默认值都是开启状态的。
如果你对音质的要求很高。用普通的声卡的音频连接线不能达到你的要求，在听CD或VCD时你可以直接将音箱接到光驱的耳机插孔上，因为这种是数字输出效果，要比使用原来的模拟信号输出好很多，失真也小。
如果你平常不爱听CD，建议好将声音属性中的MIC和CD都关掉，这样可大大避免杂音。具体的解决方法是双击系统任务栏中的小喇叭图标，然后把CD-ROM和MIC PHONE两项静音即可。
至于具体低、高音的设置，比较理想的方案是在声音属性中将你声卡的低音滑杆调到60%处，高音调到80%，总的系统音量应放到85%左右。当然，你也可以依你个人的品味随意取值。
对于采用ALC650 AC97音效芯片的nForce2和SIS 655芯片组的主板，在播放音频文件时容易出现爆音的现象。这是因为它对DirectSound的硬件加速支持存在一些问题，只需运行DirectX诊断工具，在“声音”速项中降低“硬件的声音加速级别”就可以减低爆音的程度。
正确调节CPU主频与内存频率
CPU主频与内存频率都是影响集成主板特别是其显示性能的重要因素，现在主板对非标准外频都有分频比例，一般情况CPU超频时内存可能就要降频使用。那么CPU主频与内存频率谁的影响更大呢？
对于支持双通道DDR内存的集成主板来说，内存带宽已经足够，性能瓶颈主要来自CPU，所以适当调高CPU频率会带来更高的性能。对于那些只支持单通道DDR内存的集成主板来说，它们的性能瓶颈来自内存带宽，而不是CPU，将内存频率适当会更为合理一些。
