我想請教關於降電壓跑會讓系統出問題ㄇ~
降CPU電壓~~會導致系統不穩嗎~~如顯示卡過燙~~或一直重開機~~

降電壓降到最穩的狀態就好啦~ 如果降到過低,就會不穩.. |

因為我得機殼太小散熱不好~~power溫度又很高~~就降壓再跑ㄌ~~

對壓，我也是認為何必降壓去跑呢？正常電壓跑就好了......

這樣說好了， 如果1.175V跑得穩的話，那Intel(or AMD?)就不用定這個1.5V了。 |

降電壓可以讓溫度降低..........  上次看一棵TB 1GHz 用 1.75V跑... 用的Cooler不是非常夠力.... 待機破50......比室溫高了20度左右.... 全速60度左右..... 所以一直測試....電壓降到1.325V..... 待機溫度只比室溫高五度左右....... 全速溫度也只增加到比室溫高十度....... 耗電量也降低了.......... 溫度也降低............... 這樣很好啊.................... 還有空間可以小超外頻......................

其實大可不必如此啦!根據intel或AMD說法他們在CPU製程中最起碼用double的電壓來test穩定性!

所有的電子元件都有其正常工作的電壓範圍，超出這個範圍以外， 製造商就不保證元件可以正常工作了。 CPU這種高速運作的元件對於正常工作電壓更是有嚴苛的規範， 以Intel P4來說，暫態的電壓變化了不起也只容許不到200 mV， 以額定1.5V工作電壓來看的話，你最多可以低到1.325V(2.53GHz P4 @ full load) 這裡有P4 datasheet的連結，有興趣可以看看 http://developer.intel.com/design/Pentium4/datashts/ AMD的CPU我不熟，不過道理都是一樣的。 如果真的調低電壓還可以正常工作的話，那大家也不用為了散熱的問 題搞的焦頭爛額的了 。  |
