The rapid development of technology causes hardware technology is also experiencing rapid pekembangan, so that the existing hardware to be fast using, Computers is an electronic device capable of performing several tasks as follows, receive input, process the input earlier in accordance with the program, save the commands and the results of processing. The purpose of this study is to show how much influence is given by overclocking and downclocking process to processor performance, to know the effect on the working temperature generated and the power used from the process. This research method is data analysis with tools that have been prepared. The result of this research is by application of benchmark of synthesis, graph of which shows that the higher the value hence the better its performance, except in Super Pi application which uses second time unit (s) where less time required in test indicate optimal processor performance, to overcome from the need for high computing and so as not to rush to upgrade hardware and also to save more cost in hardware upgrade. The conclusion is the frequency of downcloking generated by 1000 MHz, standard frequency 3000 MHz, Overclocking frequency of 3750 MHz, unstable system, with the overclock system will be unstable until lag / hang unstable system occurs at frequencies above 3.75 GHz.

Over the past 3 years a frequency standard of very high precision has been installed in Canada. It is composed of equipment located in three different laboratories in Ottawa, Ontario, but separated by a few miles. Intercomparison of frequency between these laboratories, which is done by sending signals over telephone lines and related techniques, is briefly described. Results indicate frequency stability of about 2:1010 over short and long periods. Absolute frequency is determined from astronomical observations. International inter-comparison is carried out by phase measurement of standard frequency and by observations of time signals; some of the results are presented.

Frequency Correction

The fatigue-crack growth behavior of annealed types 304 and 316 stainless steels is determined over a range of cyclic frequencies in an air environment at temperatures of 800°F (427°C), 1000°F (538°C) and 1200°F (649°C). A good portion of the experimental data supports the observation that the fatigue crack growth rates at a given value of ΔK increases with decreasing frequencies. The behavior ot each temperature is normalized relative to the behavior at a “standard” frequency of 40 cpm, and a simple frequency correction factor is derived. This frequency correction factor, more applicable to type 304 than to 316 stainless steels, is further coupled with temperature effects data taken at the “standard” frequency and combined with a stress ratio correction to furnish estimates of the fatigue crack growth behavior of those two steels over a fairly wide range of parameters.
