I have RB433AH ROS 3.13, firmware 2.16
using 2 x XR5 in dual-nstreme mode. the voltage is 11V, standing still
when the cpu is set to 680MHz everytihng is ok
but when I set it to 800MHz the RB works for a while and then reboots
there is nothing wrong in the log
I don't know if the watchdog is going to help me

is the cpu overheating??

Is it being cooled ??

I would check the power supply, how many amps is it's output. The XR5 are power hungry and demand up to 1.8 A each and 3.3 VDC of operation voltage and you are using 2 in the same RB

I agree on the power supply. I would also use a higher voltage supply. The MT standard PS is now 24 volts up from their old standard of 18v.

11 volts is at the bottom end and the overclocking might be causing it to drop.

The MT part number 24HPOW should work fine. It puts out 38 watts.

AFAIK 800Mhz is OCed value and your boards just MIGHT work on this frequency - but 680Mhz is default it MUST work on every board.
