I adjusted the External Clock(CPU/PCI) up to 110Mhz and set the AGPCLK/CPUCLK(AGP Clock) as Fix(66Mhz) ,my system hanged up and became unstable. Is it because that the AGP Fix (66Mhz) function not working?

Merry Xmas and Happy New Year :-)

This is RAMBUS memory frequency issue. If you running External Clock(CPU/PCI) as 110Mhz, it would cause the RDRAM clock up to 440Mhz x2. The RDRAM Clock would too high over the standard RDRAM Clock. Suggest you could try to set up RDRAM Bus Frequency as 300Mhz for testing .
