Poweredge 2650 支持 64 位嗎？
我想弄清楚 poweredge 2650 伺服器是否支持 64 位？它有 2 個英特爾至強處理器 @ 3.2ghz L2:512kb L3:1MB 我相信是在 2004 年的某個時候製造的。

它缺少
lm標誌（長模式），所以答案是否定的，它不支持 64 位。可以在此連結中找到範例參考。
不，您的 CPU 不支持 EM64T，您的主機板也不支持支持 EM64T 的 CPU，根據Intel 的常見問題解答：
問：我目前的 533 MHz FSB 系統（例如 SE7501WV2）是否支持採用英特爾擴展記憶體 64 技術的英特爾處理器？
答：沒有。
這表明 EM64T 僅適用於 800MHz FSB 和更快的 CPU。此外，根據您的主機板在PowerEdge 2650規格中列出的 533 MHz FSB，您的主機板不支持 EM64T CPU 。
在任何系統上確認這一點的簡單測試是下載 64 位 Linux live CD 並嘗試從 CD 啟動。
根據規格，您的特定 CPU 可能是其中之一：
