How to overclock a graphics card

Once you’ve finished tinkering with your core clock speed, the next step involves putting it back to stock, but be sure you have your maximum stable overclock noted down. By putting the core clock back to stock speed, it allows you to perform the same method for the memory clock speed by increasing the speed in increments.

Generally, the memory clock speed will have a much bigger scope for overclocking than the core clock, and due to that, we normally increase it by 20MHz increments. Once you increase it, you can repeat the steps of stability testing and run FurMark for 20 seconds after each application of the new settings.

Memory clock speeds will normally raise by 100MHz+ so you can expect this process to take a little bit longer than the GPU core clock speed overclocking. Remember once the system becomes unstable, you need to drop it down to the last stable overclock and then you have a 20MHZ scope from being stable to being unstable. This allows you to increase the memory clock speed by 5MHz at a time and to find that maximum overclock to squeeze the last little bit out.
