If your graphics card needs an jolt, your best option for increasing the speed is overclocking. Overclocking is a process whereby the graphics card is modified so as to perform at a higher speed than intended. Overclocking a graphics card is accomplished using software applications that can increase the clock rate. By increasing the clock rate, the graphics card is able to handle more complex graphics. Most applications offer easy-to-configure wizards for overclocking your graphics card and can help you determine what clock rate is best for your graphics card.

Step 1

Determine the make and model of your graphics card. You may already know this but if you don't, you can find out by either consulting the documentation that came with your computer or by running computer management software such as Sandra Suite or Belarc Advisor.

Step 2

Research the optimal overclocking settings for your graphics card. When increasing the speed of your graphics card, it is important that you do not exceed limitations that could cause your graphics card to malfunction. Simply searching the make and model of your graphics card along with the term "overclock" should point you to websites that can offer advice on the best clock settings.

Step 3

Download and install the overclocking software of your choice.

Step 4

Launch the overclocking software.

Step 5

Select your graphics card as the hardware you would like to overclock.

Step 6

Adjust the graphics card clock settings. Generally speaking, overclocking software will present sliders that can be moved up or down to increase or decrease the core clock, shader clock and memory clock. Refer to the research conducted in step two for optimal clock settings.

Step 7

Test your new graphic cards settings by running a 3D benchmarking program such as Futuremark (see Resources). Continue to adjust the settings until you achieve maximum performance while remaining stable in operation.
