You can try to do the following test, which stresses the CPU even more:
$ wget https://raw2.github.com/ssvb/cpuburn-arm/master/cpuburn-a8.S
$ arm-linux-gnueabihf-gcc -o cpuburn-a8 cpuburn-a8.S
And then run the resulting binary 'cpuburn-a8' on your device.
If you could also monitor the temperature and/or the current draw,
that would be really awesome.
I've started cpuburn-a8 in first console and online radio in second console.
1.20Ghz \ 1.55V - reboot after 5min ,current - 11.1 watt .
1.15Ghz \ 1.55V - cpuburn-a8 segfaults after 35min ,online radio continues
playing, current - 10.2 watt , device was extremely hot !
PSU - 5V\6A .
Do you have results from A10 tablets or sticks ?
I think they will fail even at "nominal maximum".
There is another thread covering some cpuburn + power measurements
(which btw run fine for hours)
Tablets might be a little trickier, as they are usually sandwitched in;
but I don't even expect issues there.
I think A10, A13 and A20's where tested plenty for stabilty here ...
Alexsey gave us an interesting link today about ram tuning:

this should help us all greatly eventually.
