跑了下分有2500分正常不那3220的机器都显示满频的

是独立服务器么?
Intel的CPU一般都有speedstep
在空闲状态下降低频率来降低功耗.
当负载高了它会自动提升频率.
所以一般来说是正常的. 只要负载高了它会自动提升回去就对了.
当然不排除BIOS里设置错了把CPU强行降频了

打包的时候也不会全部到2.4G

作者: domin 时间: 2010-10-31 03:06
那是否提升了?
打包很多时候是需要硬盘IO而不是CPU

那跑分测试的时候呢? 也只偶尔出现全部2.4G

大多是1-2个核心到2.4G

跑分的时候你可以再开一个SSH看cpuinfo

让机房在BIOS里面改一下那啥自动降频的功能。。
