I have an ABIT VT6X4 motherboard that I think only supports up to an 800mhz processor. I have changed the bus speed in the bios from 133mhz to 150mhz. This seems to be the only thing that I can do which will change the speed from 800 to 900. I have more than enough cooling, so I'm not worried about over heating. How can I overclock it even more? Would updating the bios allow me to change it to higher settings? Thanks for any help!
