Max clocking of ADSP-BF706 EZ-KIT Mini

I'm trying to set up set up the ADSP-BF706 EZ-KIT Mini for maximum processing speed. If I write a simple assembly routine to pulse one of the GPIO pins high and low in an infinite loop, the frequency of the pulse train is 8.333 MHz. I guess this is because I have 3 instructions in the loop and the crystal on the board is 25 MHz (I get the same result even in C). I'm using the board with CrossCore. The CGU0_CTL_MSEL is set at 0x20, but this is clearly not operational since the pulse train should be much more than this. I would really appreciate some help.
