See the built-in help for "render aosamples" and "render aasamples"...
The aa and ao sample counts are multiplicative. The defaults are
12 aa and 12 ao samples per pixel (144 total). To prevent GPU kernel
timeouts, the best is to just increase the aa sample count which also
increases the total number of ao samples taken. If you use the interactive
RT mode, it prints the number of accumulated samples as it runs, so that
can be a useful guide when you've turned on things like DoF that require
much greater sample counts for good image convergence...

Cheers,
