關於雙CPU的問題
 

請問一下
小弟目前用的是XP SP1
會有雙CPU的功能
那假如把作業系統換成WIN2000的話
那是否WIN2000裡面會沒有這項功能呢?? :drtyt76h6

你雙CPU應該是P4裡的超執行緒(Hyper-Threading)的功能吧,
目前好像只有XP支援這功能,WIN2000並沒有.

確定一下再回答比較好唷:)

Win2000確定可支援雙CPU(因為我正在使用)

2000 XPpro 2003均支援

是哦,那為什麼intel官方網頁只寫了XP,見下方網頁.

這很有趣..

因為2000確確實實支援HT
這是我的電腦..

微軟網站也有公佈文件

(右邊有個exe檔案可下載解開是word檔)

All versions of the Windows 2000 operating system are fully compliant with HT and should run without error on HT-enabled systems. However, neither Windows 2000 nor any of its service packs support the identification of HT processors. The type of modifications that are required for HT processor identification and support are not typically supported in a service pack. There are no plans to introduce this support in any future Windows 2000 service pack.
As a result, Windows 2000 treats each logical processor as if it were an individual physical processor. The operating system attempts to start each logical processor in the sequence in which it was listed by the BIOS until the number of processors that have been started is equal to the processor license limit for that version of the operating system.

XP兩版本都支援..(不過在這之前我一直以為Home Edition不支援 multiprocessor所以不支援HT:decfghi6: 我錯了.. :56gtyhu: )

2003當然也支援

我想是Intel跟Microsoft沒做好溝通吧... :sxde45fty

個人是比較相信微軟的說法啦 因為
1.自身情況的確如此
2.OS支不支援 OS廠商比較清楚

win2000 pro winxp pro均支援雙處理器，因此你只要使用p4這類支援HT
技術的處理器均可以發現有模擬出兩顆處理器...

那XP 家用版的有支援Hyper-Threading的功能嗎

有呀:)(起碼微軟說有)

上面po了那麼多還附了微軟文件連結
我白po了 我好傷心呀~~ :56gtyhu:
