Overclocking of Intel Core 2 Processors. Part III

7. If a check of overclocked computer has finished without any delays, reboot it, increase the FSB frequency by 5 or 10 MHz and check its workability again. Continue doing this until the system is fail.

8. If there is a delay, you can decrease the FSB frequency to return the system into its normal mode. But if you want to know a limiting processor frequency, you have to increase the core power supply voltage by using the “CPU VCore Voltage” or “CPU Voltage” parameters. You must change the power supply voltage gently and no more than to 0,1-0,2 W (up to 1,4-1,5 W). While testing a computer with increased processor power supply voltage, pay special attention to its temperature which must be no more than 60C. The final aim of this stage of overclocking is to find a maximum FSB frequency, with the help of which the processor can operate for a long time without delays and heating.

9. Select optimal parameters of memory. After increasing of FSB frequency, a memory frequency has also increased. An actual value of memory frequency can be calculated manually or with the help of utilities EVEREST, CPU-Z and other. To accelerate memory, you may increase its frequencyor decrease timings; and to check its stability – may use special memory tests: an utility MemTest or buit-in memory tests in diagnostic programs EVEREST and similar to them.




10. After the processor has been overclocked and optimal parameters of memory bus have chosen, you have to test the speed of overclocked computer and stability of its operation comprehensively.
