Same here. My unmodified miner gets poolside results of anywhere from 250-500 kh/s. Using the 500 kh/s spike to make any claims doesn't make a lot of sense. My average rate is somewhere around 360-370.
As has been said many times in this thread, a faster hashrate does not necessarily mean better overall performance. The rest of the miner needs to be taken into account. I can think of several issues off the top of my head that would prevent improved performance (and even worse performance) with overclocking. Even the firmware could become an issue (ever played an old DOS game that didn't have an FPS limiter on a modern machine?).
I'm waiting to see what the numbers look like after another 24 hours.

There are no problem or performance issues at higher frequencies, except if HW error rate is increased. I'am using 230400 serial baudrate and the hashrate/freq ratio is constant.
