我试图找出是否一个POWERGE 2650服务器是64位的能力？ 它有2xIntel至强处理器@ 3.2ghz L2：512kb L3：1MB我相信在2004年某个时候制造。

它缺lesslm标志 （ 长模式 ），所以答案是否定的，它不是64位的 。
在这个链接中可以find一个示例参考。
不，您的CPU不支持EM64T，而且您的主板不支持支持EM64T的CPU，根据英特尔的FAQ ：
问：目前的533 MHz前端总线系统（例如SE7501WV2）是否支持采用英特尔64位内存扩展技术的英特尔处理器？
答：不。
这表明EM64T仅适用于800MHz前端总线和更快的CPU。 此外，根据PowerEdge 2650规格中列出的主板533 MHz FSB，您的主板不支持EM64T CPU。
在任何系统上进行简单的testing就是下载一个64位的Linux live CD并尝试启动光盘。
根据规格，您的特定CPU可能是其中之一：
