ASUS AC68行货改造CFE扩大5G频率表及发射功率，超频CPU内存，读写USB3硬盘速度超60MB

五月中邪入了渣米路由，折腾了3个月实在无法忍受各种功能缺失及基本稳定性都无法保证。入了Ac68行货。整个世界变得美好了～～～

确实一分价钱一分货，但是行货貌似TX power规定的比较严格。貌似调成最大也只有50wm。想一劳永逸调成更高的只能改CFE上美版，而且1.1.6.0国行内存速度锁定在666，nvram改800会无法启动需要reset。美版没有该限制。

@RT-AC68U:/tmp/home/root# wl txpwr_target_max
Maximum Tx Power Target (chanspec:0x1001): 15.00 15.00 15.00

15dBm只有30mw发射功率

下载美版CFE dumpling，改3处mac地址为本机相应地址，或者在行货版本CFE改两处区域CN为US，然后通过刷入DDWRT才能写CFE区域。通过mtd write XXX.bin mtd0 写入cfe重新启动即可。然后通过 nvram 超频主频内存至 1200,800 完全稳定运行。

@RT-AC68U:/tmp/home/root# nvram get clkfreq
800,666
@RT-AC68U:/tmp/home/root# nvram set clkfreq=1200,800

更新！：测试发射功率能有23.50dBm最大发射功率到了大约225mw

更新超频至1400，800.稳定运行，加了风扇温度63度一下
