You will need
  • - Computer with Windows;
  • - CPU Stability Test.
So, in order to increase the frequency of operational memory, go into the BIOS. After this, go to advanced settings (can they be called Advanced Chipset Settings or some other similar way). To change the timings to find the field responsible for it (Current Latency or similar) and put the minimum value. For example, if is 3, place 2.
Now try increasing the frequency of the memory. To do this, here, find, responsible for the speed of the system bus. It might be called FSB Speed or similar. Put frequency of the bus is 1 step greater than that which is you now. It is better to change the frequency at minimum value, no more than 5 MHz.
After changing the bus frequency in the BIOS, save settings, load the operating system and run the program to test stability of CPU and memory. In this respect, well-proven program CPU Stability Test.
If the test utility showed no problems, feel free to go back to BIOS and increase the frequency of the system bus (together with the processor and operative memory) in a step. Then again, save settings, load operating system and test stability. The cycle should be repeated until, while it will not show the instability of the current configuration. In this case, you should return to BIOS and revert at a frequency of 2 steps back.
