In order to overclock the CPU, we manually started step by step to increase the FSB, beginning from the default 200. The multiplier is set by default at 14.

We finally reached 255 MHz for the FSB, where we were able to access Windows and work without problems. We then ran PCMark05 and SiSoft Sandra 2005 in order to check the stability of the processor. We had also tried with a higher FSB, at 260 MHz, but there were problems running PCMark05.

With the FSB set at 255 MHz, the Core speed went up to 3.57GHz.

- The Tests

By overclocking your D 820, you gain something in all tasks. Even in games, the actual increase in framerate was quite substantial. Note that we overclocked the processor only for testing purposes. You should realise that such an action can damage your CPU or make its life expectancy shorter. Do it at your own risk.
