我买了一些可以超频的记忆棒。默认频率为 2.4GHz,频率最高可配置为 3.6GHz。我在 BIOS 中配置了频率和电压,将频率设置为 3.6GHz。然后我运行memtester86 8.1,测试超频是否稳定,它通过了所有测试,在3.6 GHz上没有错误。最后进入操作系统(我的操作系统版本是18.04),执行sudo dmidecode --type 17 | grep -i speed
,如下图:
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s

Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
Speed: 2400 MT/s
Configured Clock Speed: 3600 MT/s
我想知道我记忆的“实际”频率是多少?我超频成功了吗?我尝试了另一个命令,sudo lshw -short -C memory
,它显示了这一点:

只会让我更加困惑。与操作系统无关的剂量超频?或者我应该添加一些有效负载来让内存加速?你能给我一些建议吗?谢谢!
