How to check RAM frequency (overclock)

[bengalih]

On my RT-AC68U I have used:

nvram set clkfreq=1000,800

I have the following output:

admin@router-asus:/tmp/home/root# cat /proc/cpuinfo
Processor       : ARMv7 Processor rev 0 (v7l)
processor       : 0
BogoMIPS        : 1998.84

processor       : 1
BogoMIPS        : 1998.84

So my BoboMIPS shows ~2 times the set CPU frequency, which appears accurate.

However, how can I check the RAM frequency to see what it is actually running at and not what "nvram get clkfreq" shows (which is often inaccurate)?

Thanks

I believe /proc/cpuinfo is the most reliable way of determining what the current CPU clock speed is for that model of router.

Yes, but I'm not asking about the CPU clock speed. I'm asking how to determine the RAM speed.

Sorry, my mistake.

Sorry I just came across this thread:
nvram get clkfreq
Get you cpu and memory clock.

That's what he's setting in post #1. He want's to know the actual RAM speed, not the contents of the variable.

Sorry. How's your router temp with the overclocking. Any active cooling?

 

[ColinTaylor]

No extra cooling here. But then I live in the UK where it never gets really hot.

The only way is to monitor the output on the serial console as the router is powered on, and the bootloader initializes the hardware.
