1 如何超频
1.1 选择合格的电源
超频使用{{{1}}}需要保证有稳定可靠的电源供应，这包括标称真实，质量可靠的电源适配器，以及低阻抗的Type-C连接线（通俗讲就是铜芯足够粗，旧款为MicroUSB连接线）。
1.2 保证散热措施
超频会令{{{1}}}发热增加，必须使用金属外壳进行散热，或DIY使用风扇进行主动散热，塑料外壳将没法胜任。
另外TF卡也建议使用能支持高温条件下正常工作的TF卡，可以选购行车记录仪专用的TF卡;
1.3 超频测试固件
进入ssh终端，输入以下命令：
cat /sys/devices/system/cpu/cpu[04]/cpufreq/scaling_max_freq
1.4 超频前后的性能测试
测试命令：
openssl speed -evp aes-256-gcm
1.5 超频方法
1.5.1 修改内核解锁更高的CPU频率
修改完成后，重新编译内核，并制作SD固件：
./build.sh kernel ./build.sh sd-img
1.5.2 验证CPU是否超频成功
执行以下命令让CPU产生负载：
dd if=/dev/zero of=/dev/null bs=1& dd if=/dev/zero of=/dev/null bs=1& dd if=/dev/zero of=/dev/null bs=1& dd if=/dev/zero of=/dev/null bs=1&
