Overclocking a modern graphics board is easier than ever most of the time, you can raise performance by turning up a few sliders in your GPU configuration utility.įirst, make sure that you’ve downloaded the latest drivers from the manufacturer’s Website. Then you can stick with the current overclocking settings, or try again with a slightly faster speed. If your computer remains free of blue screens or sudden restarts after a few hours of number-crunching with one of these tools, you’re probably in the clear. Use Prime95‘s Torture Test mode or Linx to push your PC to its limits, thereby giving you an idea of your system’s maximum clock speed. Next, run a benchmark utility to stress-test your CPU’s new configuration. That number will fluctuate, depending on what your PC is doing from moment to moment. On CPU-Z’s ‘CPU’ tab, look at the number under ‘Core Speed and Multiplier’. Check your system specs via CPU-Z to confirm that your settings held-they can be lost if something goes wrong during the tweaking process. If this boot doesn’t produce error messages or furious restarting by your machine, you’re on the right path. Just boot into the BIOS, increase the CPU multiplier number by one, save, and boot into Windows.Ĭheck the Core Speed and Multiplier tabs. With K-Series chips, you can easily modify the multiplier from the ‘Performance’ settings in your BIOS. You can tweak the multiplier in your BIOS.We tried overclocking a test machine running one of Intel’s unlocked K-Series chips, a Core i7-2600K CPU running at a base speed of 3.4GHz (that number is the product of the processor’s base clock rate, 99.8MHz, times the multiplier, 34). But you’ll still be able to get some extra mileage out of your CPU.
If you don’t have an unlocked processor (Intel’s K-Series and Extreme Edition, or AMD’s Black Edition), you’ll have less flexibility, as unlocked processors offer more multipliers to adjust. To get more performance from your processor, you need to increase one of these two variables.
The advertised speed of your CPU is calculated by multiplying the base clock rate by a multiplier.
