"When I was testing the Xpower out, the problem I had always run into with the test CPU was trying to run the processor at bclocks higher than 205Mhz. It was just a bit stubborn. 200x21 and 205x20 were no problem, above that limit was a no go. The Xpower did allow me to reach up to a 213Mhz bclock for an improvement over prior boards. The design seems to work allowing me the highest stable overclock on air for this chip to date"
