在ubuntu中双核cpu的频率是怎么算的?
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

这就是自动降频的问题~~

在终端执行cpufreq-info返回的数据
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to linux@brodo.de, please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0
hardware limits: 600 MHz - 900 MHz
available frequency steps: 900 MHz, 600 MHz
available cpufreq governors: powersave, conservative, userspace, ondemand, performance
current policy: frequency should be within 600 MHz and 900 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 900 MHz.
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 1
hardware limits: 600 MHz - 900 MHz
available frequency steps: 900 MHz, 600 MHz
available cpufreq governors: powersave, conservative, userspace, ondemand, performance

那怎么样才能全速运行呢?lerosua 写了:这就是自动降频的问题~~

启动几个很占CPU的进程把CPU占到100%,就全速运行了。tzwywei 写了:那怎么样才能全速运行呢?lerosua 写了:这就是自动降频的问题~~

这样也是最高900MHz,根本上不到1.8Gpoet 写了:启动几个很占CPU的进程把CPU占到100%,就全速运行了。tzwywei 写了:那怎么样才能全速运行呢?lerosua 写了:这就是自动降频的问题~~

尝试在主板BIOS禁用相应的选项吧。
