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&
