Like with any device OCing is kinda device dependent.
mines is tolerant up to about 1.2 to be stable. I can rock 1.44 but i get a few reboots there per day.
honestly though, i don't really notice any speed difference for day to day use. I run at 1.0 with the Matr1x kernel and it's plenty fast.
I get similar results to slacker's. I clock at 800MHz most of the time though.
