I've tried ctrl + F1 followed by DEL on boot up to get the CMOS configuration utilities which opened OK but the CPU speed was greyed out so I couldn't select it to clock it. Does anyone know what I should do now?
If you are needing to set the CPU multiplier and it is greyed out in the Bios then you will have to adjust a jumper or dipswitch on the motherboard to set the frequency.
If you dont need to set this due to a CPU change or similar but are wanting to experiment with overclocking I would advise againt it. It sounds easy, it is easy, but get it 1mhz wrong and you fry the cpu!
Cooling is also a major factor and you will need to make sure your cooling is more than adequate.
Please...think carefully..very very carefully before attempting this.
