DT200-11億佳做口碑
與顯卡相比，聲卡占用的系統(tǒng)資源要少很多，但通過合理設(shè)置仍會節(jié)省一些系統(tǒng)資源。比如在Windows環(huán)境中關(guān)閉“音量控制”中的StoreWide或3D Depth兩個選項(xiàng)，會大大減少聲卡的CPU占用率，一般Windows的默認(rèn)值都是開啟狀態(tài)的。
如果你對音質(zhì)的要求很高。用普通的聲卡的音頻連接線不能達(dá)到你的要求，在聽CD或VCD時你可以直接將音箱接到光驅(qū)的耳機(jī)插孔上，因?yàn)檫@種是數(shù)字輸出效果，要比使用原來的模擬信號輸出好很多，失真也小。
如果你平常不愛聽CD，建議好將聲音屬性中的MIC和CD都關(guān)掉，這樣可大大避免雜音。具體的解決方法是雙擊系統(tǒng)任務(wù)欄中的小喇叭圖標(biāo)，然后把CD-ROM和MIC PHONE兩項(xiàng)靜音即可。
至于具體低、高音的設(shè)置，比較理想的方案是在聲音屬性中將你聲卡的低音滑桿調(diào)到60%處，高音調(diào)到80%，總的系統(tǒng)音量應(yīng)放到85%左右。當(dāng)然，你也可以依你個人的品味隨意取值。
對于采用ALC650 AC97音效芯片的nForce2和SIS 655芯片組的主板，在播放音頻文件時容易出現(xiàn)爆音的現(xiàn)象。這是因?yàn)樗鼘irectSound的硬件加速支持存在一些問題，只需運(yùn)行DirectX診斷工具，在“聲音”速項(xiàng)中降低“硬件的聲音加速級別”就可以減低爆音的程度。
正確調(diào)節(jié)CPU主頻與內(nèi)存頻率
CPU主頻與內(nèi)存頻率都是影響集成主板特別是其顯示性能的重要因素，現(xiàn)在主板對非標(biāo)準(zhǔn)外頻都有分頻比例，一般情況CPU超頻時內(nèi)存可能就要降頻使用。那么CPU主頻與內(nèi)存頻率誰的影響更大呢？
對于支持雙通道DDR內(nèi)存的集成主板來說，內(nèi)存帶寬已經(jīng)足夠，性能瓶頸主要來自CPU，所以適當(dāng)調(diào)高CPU頻率會帶來更高的性能。對于那些只支持單通道DDR內(nèi)存的集成主板來說，它們的性能瓶頸來自內(nèi)存帶寬，而不是CPU，將內(nèi)存頻率適當(dāng)會更為合理一些。
