Although P4i45G / P4i45GL / P4i45GV offers stepless control, it is not recommended to perform over clocking. When the CPU frequency of P4i45G / P4i45GL / P4i45GV is set to perform over clocking, other clocks, such as PCI clock, AGP clock, and Memory clock will also be overclocked proportionally. Frequencies other than the recommended CPU bus frequencies may cause the instability of the system or damage the CPU and the motherboard. 6
