我想弄清楚 poweredge 2650 服务器是否支持 64 位？它有 2 个 Intel xeon 处理器 @ 3.2ghz L2:512kb L3:1MB 我相信是 2004 年生产的。

任何帮助表示感谢
答案1
它缺少lm旗帜（长模式），所以答案是不，它不支持 64 位。
示例参考可以在这里找到此链接。
答案2
不，你的 CPU 不支持 EM64T，并且你的主板也不支持具有 EM64T 功能的 CPU，根据英特尔常见问题解答：
问：我当前的 533 MHz FSB 系统（例如 SE7501WV2）是否支持采用英特尔 64 位扩展内存技术的英特尔处理器？
答：没有。
这表明 EM64T 仅适用于 800MHz FSB 及更快的 CPU。此外，根据主板的 533 MHz FSB 列表，您的主板不支持 EM64T CPUPowerEdge 2650眼镜。
在任何系统上确认这一点的一个简单测试是下载 64 位 Linux 实时 CD 并尝试从该 CD 启动。
根据规格，您的特定 CPU 可能属于以下之一：
