我正在尝试确定我的 CPU 的 Vcor​​e 电压，但失败了。我的 CPU 是华擎 570M Pro主板中的 Ryzen 3700X，使用 Arch Linux（完全更新）。

我下载了lm_sensors包，运行sensors-detect并接受了所有扫描，然后运行watch sensors​​. 当 CPU 空闲且仅运行终端时，我的输出附在下面。

在负载下，唯一变化的电压值是 in0，最高可达 720 mV（在一个内核上 100%）。一些在线指南建议 in0 通常是 Vcor​​e，但是对于这里的情况来说，它太低了。3700X 的正常工作电压介于 0.2 V 和 1.5 V 之间，当单核在最大负载下升压时会达到后者。（根据我的测试，温度和风扇速度看起来是正确的。）

我该怎么做才能正确读取我的 Vcor​​e？谢谢你。
