openSUSE Leap 15.0 下 CPU 不会睿频？

最近发现跑程序的时候电脑有些安静，然后我就发现系统即时满载，cpu似乎也不会自动睿频。

$ cat /proc/cpuinfo | grep -i mhz                                                   
cpu MHz         : 3200.000
cpu MHz         : 3200.000
cpu MHz         : 3200.000
...

系统满载运行4分钟后：

$ uptime

Core 5:        +80.0°C  (high = +82.0°C, crit = +100.0°C)

下面是一些配置信息，不知道有没有大佬可以帮忙看看是什么问题。

CPU：Intel(R) Core(TM) i7-8700 CPU @ 3.20GHz
显卡：GeForce GTX 1050

kernel 启动参数：

$ cat /proc/cmdline

内核版本：

$ uname -a

系统版本：

$ cat /etc/SUSE-brand                                                              
openSUSE
VERSION = 15.0

其他一些选项：

$ cat /sys/devices/system/cpu/intel_pstate/no_turbo  
0
$ cat /sys/devices/system/cpu/intel_pstate/max_perf_pct                            
100

BIOS里也没有选限制性能的选项。

这意思是已经睿频了么？

插楼问一下那个27.8度是个默认值吗？用screenfetch显示的cpu温度经常是这个，个别内核会显示正常温度，而且还不是每次开机都正常，有时也会显示27。8

看样子已经睿频了

这个我也不清楚,

笔记本平台（fedora 30)

acpitz-acpi-0
Adapter: ACPI interface
temp1: +27.8°C (crit = +105.0°C)
temp2: +29.8°C (crit = +105.0°C)

Dell台式机(opensuse leap 15.0)

iwlwifi-virtual-0
Adapter: Virtual device
temp1: +27.0°C

acpitz-acpi-0
Adapter: ACPI interface
temp1: +27.8°C (crit = +119.0°C)

相同的Dell台式机（centos 7.7)

acpitz-virtual-0
Adapter: Virtual device
temp1: +27.8°C (crit = +119.0°C)

全核八十度，从温度来看应该是睿了，没睿就废了（大概还能拿来煎蛋吃）。

内核太老的话，显示频率可能会不准吧，我也不是很确定。

我用的农企 CPU 也是如此，ryzen 1700 一直在处在 3.0g，但是看 7z 跑分又是睿频的。后来干脆在 BIOS 里面超到 3.7g

以前用笔记本 i7 的时候，睿频是正常的。

超频是不可能，这辈子都不可能超频的
