just here to inform i found overclocking the rt-ac68u (older versions) not working anymore with firmware 386.11 (i use merlin), 386.10 is the last known version that overclocking still works for me
 
Thanks for the data point. :)

However.

That decade-old design/hardware is great for Media Bridge mode. Well past its best-before-due date in router mode (at least for the faster ISP speeds available today).

Even overclocked, an entry-level AX class router such as an RT-AX68U will overshadow it (and yes, even with 'only' AC class clients).

What frequency are you overclocked to?

Don't remember if I overclocked my RT-AC68U but it runs fine on Merlin 386.11 with the following clock/bogomips:
Code:
nvram get clkfreq
1000/800
cat /proc/cpuinfo | grep Bogo
BogoMIPS        : 1998.84
BogoMIPS        : 1992.29
 
My Asus RT-AC68U H/W ver. A1 has been working for years at 1200,666, through all the firmware upgrades. It also worked on the latest 386.12_alpha1 when I was testing it.

Sure, there were the occasional hiccups when it wouldn't apply the clocks at a reboot, but I'd say it worked more than 90% of the time.

Whether the AC68U can be overclocked under Asuswrt-Merlin and stock firmware depends on your hardware version and CFE version, only the old hardware and CFE version have the opportunity to overclock, newer models (such as those with 1 GHz (4708C0/4709A0/4709C0) upgrade model) will not be able to overclock, when you overclock, you will be forced to downclock to 100 MHz.

Overclocking the AC68U is a bad idea in my opinion, the performance gain is pretty insignificant unless you use OpenVPN, but the heat boost is so noticeable, you're speeding up your AC68U to death.
 
I can't believe I've been around here long enough to have seen this rear its ugly head a second time now

I agree 100% if you don't mitigate the heat BUT up until recently, when I finally upgraded, I had my 68U running at 1.2/666 for over 6 years and never a hiccup with anything including OpenVPN. Secret to this which has gotten some heated discussions on this forum is having a fan blowing across the side of the unit. Bought a cheap desk fan with a clip at Walmart with 2 speeds, set it to lowest speed and voila CPU never went above 61C...usually in the range of 55-58C. Replaced the fan only once in all those years so Wally Mart makes a good product :) Noise can be annoying so placed the unit in a strategic closet within the house and range was never an issue in my home. Of course results may vary but without a doubt the best damn router I have ever owned period!
 
thanks for everyone's reply

i always use the bogomips command in ssh to check if an overclock is working

i have 3 of the routers side by side, been running them at 1200,800 for a long while (since the covid lockdown 2020) but then found out the overclock is not working anymore after upgrading 386.11, reverting back to 386.10 still get same result

now i have all 3 routers at 386.11, only 1 of them is overclocked, while the other 2 remain at base clock speed

maybe i will try 1200,666, if not working i am still fine at base speeds
