Package power limit notification

   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：

再次进入BIOS中，进入system profile settings，第一个选项默认是performance per watt(DAPC)，选择该选项后，默认是开启Turbo boost的

在system profile中选择最后一个手动模式，剩下的其他选项就可以设置了，只要修改Turbo boost为disable，其余选项均不变即可，保存后重启机器。
