Supermicro 服务器上的 Intel SpeedStep/Turbo 无法正常工作

我最近买了一台二手的 Supermicro SuperServer 6027AX-TRF-HFT3（带 2 个 E5-2687W v2）。到目前为止，它运行良好，但我注意到一件事。无论我做什么，它似乎都无法在空闲时降频或在使用时加速。我在 BIOS 中启用了 EIST 和 Turbo，并禁用了覆盖操作系统电源管理的选项。我还启用了所有我能找到的 C 和 P 状态选项。HyperSpeed 全部设置为“自动”，这是它不超频 CPU 的唯一选项。

cpupower的输出如下

# cpupower frequency-info

                  within this range.
