3.0.0.4.374.38_2 RT-AC68U no button overclock with bootloader version 1.0.1.1

[Ruudddd]

Just installed Asuswrt-Merlin 3.0.0.4.374.38_2 on the AC68U, I still have bootloader 1.0.1.1 installed.

For some reason the over clock functionality with the LED button does not work in this firmware.

I have done a factory-reset before flashing merlin and also after flashing merlin. I have rebooted the router several times after turning the over clock functionality on.

Pushing the button reboots the router as advertised, however when checking the CPU freq through nvram get clkfreq I get 800,533 no matter what the position is of the button.

Any ideas?

Cheers,

Ruudddd

It won't show you 1000Mhz.

To manually determine if OC is enabled, check the content of
admin@RT-AC68U:/tmp/home/root# cat /proc/cpuinfo

Bogomips should be around 1500 for 800 MHz and 1900 for 1 GHz.

Cool I will try that. Thanks

Easy way to do it:
Tools --> Run Cmd --> cat /proc/cpuinfo
and hit refresh

with the BL 1.0.1.1

To get overclock follow steps:

From the default:

1. check the nvram values:

nvram get clkfreq

2. in web interface go to the:
Administration --> Performance Tuning
- choose LED button Behavior as OverClock: Press the button to turn on overclock, release the button to turn off.
- press Apply

3. After restart of service PRESS BUTTON on the back of the unit and wait for restart.

4. check the nvram values (it is still the same 800,533):

nvram get clkfreq

5. NOW enter desired values (for example):

nvram set clkfreq=1000,800
nvram commit && reboot

6. After restart verify again entering:

nvram get clkfreq


In the web interface you will find under Tools / sysinfo proper valu for the CPU Frequency.

And yes it works ... I'm getting arround 65 MB/s transfer with USB 3.0 when wired to the PC.

If you are using the button, then do not change the clkfreq values, otherwise it makes the whole button meaningless. The idea of the overclock button is that if you run into stability issues and you can't boot anymore, you only have to release the button to go back to stock clock. If you modified the clkfreq value, then this fallback method will NOT work anymore.

I get the point, however this is the only way I found (on RT-AC68U) to get DDR & CPU overclocked at the same time as well as reported by clkfreq nvram variable. Correct me if I'm wrong ?

On the other hand there is still BL on RT-AC68x as E-STOP to be used when needed.

You should be able to overclock both CPU and DDR just by using the clkfreq variable.

Confirmed this still works with 1.0.2.0 on AC68U
