You can slightly overclock your Gen3 by typing the following command :
setxenv_mtd.sh 0 -b x.pll.1.pll 0x0100003b
The frequency will change from 715 MHz to 810 MHz at the next reboot.
3B corresponds to the value of the PLL frequency multiplier core (27 MHz)
(HEXcode + 1) * 27 / CPU_Mux = (3B + 1) * 27 / 2 = 810 MHz
Do not exceed the value 3B. Beyond that, the boot can not read the Nand and your Gen3 will be bricked. But 3B value is perfectly secure.
I continue to seek ways to exceed 810MHz…
Hey Could you explain, how to type in commands and where?!?
Thanks
You can use JTag to enter command. (see JTag)
In my homebrew, you can use phpshell : http://ip.of.your.wdtv/phpshell/phpshell.php
In other Homebrew, see documentation for connect via SSH or telnet.
