Core Frequency = CPU FSB Clock * CPU Ratio
Warning: Intel

845GL (MX4LR) chipset
supports maximum 400MHz (100MHz*4)
system bus and 66MHz AGP clock; higher
clock setting may cause serious system
damage.
Warning: To avoid possible CPU damage caused by
overheating, an automatic shutdown of system had been
especially designed on this motherboard. System would
be automatically power off when this motherboard with
