I only stick with merlin so no r7000 for me. Plus this thing is pretty stable for me, I also lost half my resale value unless someone can source me a new sticker
yea man, 2 years warranty is gone if you are living in the US

The utility upgrades the bootloader (AKA CFE) to a newer version, it's not just meant to modify nvram. In fact, that's why a factory default reset is required afterward - the increased clock won't be written to nvram until you do so.
Most likely the original (1.0.1.1) bootloader was broken, and required an upgrade to properly work at 666 MHz. With 306, the factory default reset code now has this little snippet (which shows that it checks first if the bootloader had been upgraded in the case of the AC68U before increasing the memory clock):
Code:
switch (get_model()) {
case MODEL_RTAC56U:
nvram_set("clkfreq", "800,666");
break;
case MODEL_RTAC68U:
if (!nvram_match("bl_version", "1.0.1.1"))
nvram_set("clkfreq", "800,666");
break;

Anything below 90C is fine.
No idea what is the actual upper limit, only Broadcom (and their licensee) know.

FYI
I had this spare usb fan, decided to use it and see what will happen with the temps on RT-AC68U
Temp reading after 10 minutes, fan on medium (quiet) placed behind the router.

Man, 88 degrees with no turbo mode/overclocking ?
if this is common for AC68U to have such high temperatures with 800/533 clocks an regular loads (not stress testing), ASUS should definitely improve cooling... make the heatsink bigger/better and make sure it actually touches the hot parts... this is ASUS' top dog consumer router, should not be skimping on stuff like that...

it is turbo, 1000/533 and both TX power at 150mW
I guess I did not mention it before.
My main point is what a small fan can do...

when you took apart the router, did you put better thermal paste on it? I did see a few ppl used copper to replace the thermal pad for CPU cooling.
you are lucky that you did change your 533 to 666, otherwise you would lose 1000 CPU overclock, lol.

I did not change the mem from 533 to 666.
If I did it - then this woudn't work with CPU at 1000MHz (at least at the current stage of things...)
Hold on... you guys are breaking my heart - updating bootloader to increase memory clock from 533 to 667 prevents further overclocking???
Didn't ASUS re-introduce Turbo mode so CPU can go 1GHz?
And - question to Merlin - if you use the latest Merlin firmware AFTER updating the bootloader to 667, can you still set clocks in NVRAM to, for example, 1200/800?

sorry, i was drunk and thought u were the op.
All I know is that it breaks Turbo Mode. I haven't tested manually editing clkfreq, so I don't know if the limitation is because Turbo mode is broken in the new bootloader, or if it's an overclocking limitation.
Turbo mode doesn't work through clkfreq, it's specially handled by the bootloader at boot time.
Asus hasn't introduced Turbo mode. It's a feature they started working on during the initial router development, and decided not to include in the final product due to stability issues they encountered with it. I only enabled it on my FW for people to experiment with it.
No idea, I didn't try. Don't really have time these days to disassemble this router and hook a serial cable to it in case it prevents the router from booting.
