with the new bootloader you may change now the cpu clock setting up to 800 mhz. just set the uboot env var "cpu_clock" and reboot. if this var is not set, the default cpu clock will be used which is 600 mhz for a standard gw2388. this might also work for gw2380, but its not tested example: env set cpu_clock 800 reset valid values are : 300 333 366 400 433 466 500 533 566 600 633 666 700 733 766 800
