I have a P6L40-A4E Main board which has the Intel 440LX AGPset chipset. I was wondering if anyone knew if this chipset only supports 60/66 MHz bus clock? and whether the 75/83 MHz settings where for internal test only? Will overclocking cause serious damage?, because I have been told that the speeds between 66 MHz and 100 MHz can be troublesome. I have a Intel 333 MHz CPU. Any information would be appreciated.
