我刚刚用 Core i5-760 CPU 构建了一台新机器。最大速度为 2.80GHz（尽管有涡轮模式）。我还完成了 Ubuntu 10.10 的香草安装。
我已将 cpufreq-selector 小程序添加到顶部面板，它的菜单只允许我选择高达 2.39GHz 的频率。如果我选择“性能”调速器，它也会显示 2.39GHz。

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0 1 2 3
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 1.20 GHz - 2.39 GHz
available frequency steps: 2.39 GHz, 2.26 GHz, 2.13 GHz, 2.00 GHz, 1.86 GHz, 1.73 GHz, 1.60 GHz, 1.46 GHz, 1.33 GHz, 1.20 GHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
current policy: frequency should be within 1.20 GHz and 2.39 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 1.20 GHz.
cpufreq stats: 2.39 GHz:13.74%, 2.26 GHz:0.09%, 2.13 GHz:0.08%, 2.00 GHz:0.08%, 1.86 GHz:0.07%, 1.73 GHz:0.07%, 1.60 GHz:0.08%, 1.46 GHz:0.08%, 1.33 GHz:0.11%, 1.20 GHz:85.61% (15560)

知道如何让 Ubuntu 和各种工具将其识别为 2.80GHz 处理器吗？理想情况下，也可以报告在涡轮模式下运行时的实际速度，但这并不重要。
编辑：我可能应该补充一点，BIOS（和 Windows）很高兴它是 2.80GHz CPU。
谢谢。
