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.
The actual speed is decided by the rate of the memory bus. The speed specified for the memory modules is the maximum speed that they are certified for. There is no performance difference between using memory chips rated at 1200 MHz and 1600 MHz, the difference is that they will fail at different bus speeds.
