本文介绍了一种解决DELL12代服务器(R620)上频繁出现CPU报警的方法。通过调整BIOS设置禁用Turboboost功能来避免CPU因温度过高而触发报警。

为什么80%的码农都做不了架构师？>>>

最近装了一批DELL 12代的服务器(R620)，运行几天后，发现在系统日志中出现很多CPU报警，如下：

CPU13: Package power limit notification (total events = 1) 
CPU1: Package power limit notification (total events = 1) 
CPU17: Package power limit notification (total events = 1) 
CPU3: Package power limit notification (total events = 1) 
CPU19: Package power limit notification (total events = 1) 
CPU5: Package power limit notification (total events = 1) 
CPU21: Package power limit notification (total events = 1) 
CPU7: Package power limit notification (total events = 1) 
CPU23: Package power limit notification (total events = 1) 
CPU9: Package power limit notification (total events = 1) 
CPU25: Package power limit notification (total events = 1) 
CPU11: Package power limit notification (total events = 1) 
CPU27: Package power limit notification (total events = 1) 
CPU31: Package power limit notification (total events = 1) 
CPU15: Package power limit notification (total events = 1) 
CPU29: Package power limit notification (total events = 1) 
CPU17: Core power limit normal 
CPU1: Core power limit normal 
CPU3: Core power limit normal 
CPU19: Core power limit normal 
CPU21: Core power limit normal 
CPU5: Core power limit normal 
CPU23: Core power limit normal 
CPU7: Core power limit normal

查了一下google资料，解释说是应该是CPU的保护温度阈值在BIOS中设置的过于低了，于是在BIOS中搜索一番后，没有发现设置的CPU温度报警阈值的地方。在dell官网找到一份12代服务器的资料后，得到如下解释：
