在 Ubuntu/Thinkpad 上设置 CPU 温度限制阈值

在 Ubuntu/Thinkpad 上设置 CPU 温度限制阈值

我每小时会收到几次以下错误消息:

08.03.18 21:27  kernel  CPU0: Core temperature above threshold, cpu clock throttled (total events = 2234)

硬件规格:

ThinkPad X1 Yoga 2nd
N1NET33W (1.20 )
Intel(R) Core(TM) i7-7600U CPU @ 2.80GHz
Production date 2017.11

软件:

Distributor ID: Ubuntu
Description:    Ubuntu 17.10
Release:        17.10
Codename:       artful
Linux 4.13.0-36-generic #40-Ubuntu SMP Fri Feb 16 20:07:48 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

简历:

我都设置了电池交流表现在我的 BIOS 设置中,BIOS 是最新的。

问题是什么

问题在于,CPU 温度阈值过早达到,大约在 75°C 左右,尽管 CPU最高温度可达 100°C。温度从未超过 85°C。因此 CPU 功率会很快受到限制。

我不知道我是否遇到了制造商硬件问题,比如导热膏不足,或者是否与软件有关。在将其发送给联想之前,我想确保这不是自制问题。

统计资料

当我进行压力测试时

stress -c 4 -t 300

错误信息几乎立即出现。

i7z 给出以下输出:

如上所述,它的温度从未超过 85,但 CPU 受到限制。

但高设置可能没有效果。

thermald

因此我开始尝试使用 thermald。

这是我调整后的配置我在这里找到

这没有什么实际区别,但我至少可以看到阈值设置(最后几行):

最后的想法/问题

  • 是否可以设置 CPU 温度阈值?
  • 它是否需要设置或者是否与 BIOS/硬件有关?
  • 我的硬件(导热膏)可能有缺陷吗?
  • 或者我可能分析得完全错误?

更新 #1

在深入研究了这个主题并阅读了几篇关于英特尔 CPU 限制的文章以及其他操作系统和内核上遇到相同(或略有不同)问题的帖子后,我得出的结论是,我的笔记本电脑可能没有像我想象的那样出现故障。

虽然内核消息仍然很奇怪,但原因可能是内核 printk 级别错误或其他原因。当我的 CPU 封装温度约为 +52.0°C 且 CPU 频率仅为 1200MHz 时,我也会检索到这些消息。这根本毫无意义。

当我用压力测试测试我的笔记本电脑时,我可以看到错误消息,但实际上 CPU 并没有受到限制。如果我只测试 1 个核心,我可以获得 3,900MHz 的全涡轮增压速度。测试所有 4 个核心会将最大频率降低到 ~3,300MHz。预期行为

因此我将把这个问题放在一边——除非有人能提供更多内幕信息。

所以我的最终假设是日志很可能是伪造的,或者日志级别配置错误。因为我的笔记本电脑运行正常,既没有被限制,也没有过热。

不过,如果有人知道该如何解决这个问题,请随时回答:-)

我仍然收到阈值限制消息。

我刚刚发现一篇帖子说这个问题甚至没有用全新的X1 Extreme 第二代

为了那些正在考虑购买我所拥有的笔记本电脑的朋友们,以下是我面临的一些问题:

  • 触摸屏无法正常工作
  • 指纹不起作用
  • Hibernate 偶尔才会成功
  • 由于图形问题,在不同工作环境(办公室和家庭办公室)之间切换几乎不起作用
  • 总体而言,多显示器存在很多问题
  • 即使有大量可用 RAM,也会发生硬盘交换
  • kscreen 和 xrandr 的一般问题和各种问题

所以,我想我现在就投降,转而使用 HP 或戴尔。对于一台售价约 2500 欧元的笔记本电脑,我真的不想遇到这种问题 :-(

尝试在命令行窗口中运行 thermald。

systemctl stop thermald
#thermald --no-daemon --loglevel=info

在我的计算机上,我无法使用thermaldtlp加载来复制该问题。我打开了五个终端并在每个终端中输入:

while true ; do : ; done

所发生的一切就是五个核心以 100% 和 3100 MHz 的速度运行。没有发生任何节流,但它确实使两个笔记本电脑风扇以低速运行。通常在 Linux 中它们是关闭的(或者至少我听不到它们的声音)。系统温度为 88 摄氏度,键盘仍然响应输入此答案。不过客厅确实感觉有点暖和......

答案2

@WinEunuuchs2Unix

我已经创建了一个答案,以便讨​​论你提出的来自 erpalma 的 throttle-tool

我用这个工具玩了一会儿 - 包括几次系统冻结 :) 不幸的是,我还没有找到适合我系统的正确配置。但这个工具肯定对我的系统有影响。我第一次看到一些东西真的改变节流/温度行为。

如果没有该工具,我的 CPU 温度从未超过 85°C。安装该工具并启动服务后,我可以看到温度在压力下升至 98°C,核心频率约为 3300MHz(而不是 3187MHz)。

erpalma 建议工具 s-tui,我也绝对可以推荐。

在此处输入图片描述

  1. 在安装上述节流阀服务之前
  2. 激活服务后

我会监控我的系统几天,然后汇报。现在谢谢!

我遇到了同样的问题,出现如下错误:

Oct 14 22:30:59 p5520 kernel: [ 9481.033687] CPU3: Package temperature above threshold, cpu clock throttled (total events = 5845)

先前的答案都不起作用,但是SuperUser 上的这个答案给了我寻找相关 BIOS 设置的想法。

我已在 Lenovo E590 Ci8 BIOS 中禁用 speedstep 功能,这解决了我的问题,上述错误已消失。

编辑-:真正的解决方案 我在安装 ARCH Linux 时从实时启动安装开始遇到此问题,通过安装最新的 INTEL PROCESSOR MICROCODE 解决了此问题

答案4

当日志显示温度高于阈值时。此时温度高于阈值(95C)。英特尔 CPU 具有短期涡轮增压功能,可以在很短的时间内(不到 1 秒)消耗大量电量。如果监视器使用超过 1 秒的平均温度来测量最高温度,通常不会反映出来。这对硬件不利,但这是使 CPU 响应更快的努力。
