1 如何超频

1.1 选择合格的电源

超频使用R2S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MicroUSB连接线(通俗讲就是铜芯足够粗),经我们测试,市面有如下可选: R2spower.jpg

1.2 解锁更高的CPU频率

在FriendlyWrt Repo源代码的目录下,用vim打开以下文件:

vim kernel/arch/arm64/boot/dts/rockchip/rk3328.dtsi

在文件中搜索文本 opp-1296000000,在opp-1296000000定义后面,增加两个CPU频率的定义,分别为1.51G和1.6G,修改后的内容如下所示:

        opp-1296000000 {
            opp-hz = /bits/ 64 <1296000000>;
            opp-microvolt = <1300000>;
            clock-latency-ns = <40000>;
        };
        opp-1512000000 {
            opp-hz = /bits/ 64 <1512000000>;
            opp-microvolt = <1450000>;
            clock-latency-ns = <40000>;
        };
        opp-1608000000 {
            opp-hz = /bits/ 64 <1608000000>;
            opp-microvolt = <1450000>;
            clock-latency-ns = <40000>;
        };

修改完成后,重新编译内核,并制作SD固件:

./build.sh kernel
./build.sh sd-img

1.3 验证CPU是否超频成功

执行以下命令让CPU处于满载:

dd if=/dev/zero of=/dev/null bs=1M&
dd if=/dev/zero of=/dev/null bs=1M&
dd if=/dev/zero of=/dev/null bs=1M&
dd if=/dev/zero of=/dev/null bs=1M&

再用如下命令查看当前的CPU频率,可以看到频率已经是1.6G:

root@FriendlyWrt:~# cat /sys/devices/system/cpu/cpu[04]/cpufreq/cpuinfo_cur_freq
1608000

如何你超频不成功,可以尝试更换质量更好的电源试试。
