我办公室的是Intel(R) Core(TM)2 CPU 4300@1.80GHz最高才900HMz
变成900HMz＋900HMz＝1.8G


另外一台AMD Athlon 64 X2 3800＋应该是2G的最高频率也变成1G了
难道是双核1G＋1G＝2G？



怎么回事，根本不能运行在应有的频率上，这个与自动降频没关系吧，应该是系统识别的问题吧？请高手指教一下吧

js？~~~

这就是自动降频的问题~~

终端里
查看cpu频率调整信息

在终端执行cpufreq－info返回的数据

那怎么样才能全速运行呢？

启动几个很占CPU的进程把CPU占到100%，就全速运行了。

这样也是最高900MHz，根本上不到1.8G

会不会是ubuntu的bug

尝试在主板BIOS禁用相应的选项吧。

sudo dmidecode --type 4

amd的cpu双核原理和intel不同，主要是技术不同
具体可以google一下
我以前看过，在哪看的忘了

我的是AMD羿龙X4　9650，不知道检测的是什么频率啊！！！
