I have a Intel Q6600 @2.4GHz on a MSI P43-C51 motherboard. The motherboard has switches on it to change the speed of the FSB, as shown here, although I will probably use the option to enter the speed manually in the BIOS. Am I correct in saying that the speed of the cpu is directly proportional to the speed of the FSB? My fsb is running at '266', megahertz i presume. This is the minimum, max is 800 (as said in my bios). When increasing the theoretical speed of the FSB, the theoretical speed of the CPU goes up, which makes sense (as shown by my bios, when changing the speed of the fsb without saving&exiting). Does the speed of the FSB have to be a 'special' number, or can it be whatever integer I like? I could for example set it to 270, 271 or 274 or any other number between 266-800 MHz and they would all be fine? For the CPU voltage, my CPU has an option to keep it at automatic. My motherboard/bios has overclocking ability integrated & doesn't need to be unlocked. Should I just keep it at automatic? Or change it to manual? Cheers :) Sorry for my tech-related noob-ness ;)
