We can also make interval estimates (e.g., we are 95% confident that the interval (2.0 cm, 5.0 cm) covers the population mean).
The multiplier is then used to determine the final clock speed based on the bus speed of the processor. Set this to the appropriate multiple for the final clock speed of the processor. For an example, if you have an Intel Core i5-4670k processor that has a CPU speed of 3.4GHz clock, the proper settings for the BIOS would be a bus speed of 100MHz and a multiplier of 34. Memory Timings. The next aspect of the BIOS that needs adjusting is the memory timings.
Assume we have a Barton 2500+ which has a FSB of 333 MHz (166 MHz X 2) and we also have PC3200 memory running at 400 MHz (PC3200). This is a typical scenario because many people think that faster memory running at 400 MHz will speed up their system. Or they fail to disable the SPD or Auto setting in their bios. There is NO benefit at all derived from running your memory at a higher frequency (Mhz) than your FSB on Athlon XP/Duron systems.
