Overclocking the graphics card

Overclocking the graphics card

For most graphics cards you can apply a simple series of tricks to boost the overall performance a little. Typically you can tweak the core clock frequencies and voltages. By increasing the frequency of the video card's memory and GPU, we can make the video card increase its calculation clock cycles per second. It sounds hard, but it can really be done in less than a few minutes. I always tend to recommend to novice users and beginners, to not increase the frequency any higher than 5% on the core and memory clock. Example: If your GPU runs at 1500 MHz then I suggest that you don't increase the frequency any higher than 25 MHz increments.

More advanced users push the frequency often way higher. Usually, when your 3D graphics start to show artifacts such as white dots ("snow"), you should back down 25 MHz and leave it at that. Usually, when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Carefully find that limit and then back down at least 25 MHz from the moment you notice an artifact. Look carefully and observe well. I really wouldn't know why you need to overclock today's tested card anyway, but we'll still show it. All in all... you always overclock at your own risk.


Reference frequency This sample Overclocked 
Boost Clock: 2581 MHz Boost Clock: 2679 MHz Boost Clock: ~2800 MHz
Memory Clock: 16000 MHz Memory Clock: 16000 MHz Memory Clock: 17200 MHz 

Normally most cards out there will all tweak to roughly the same levels due to all kinds of hardware protection kicking in.  We applied the following settings :

  • Core Voltage Max
  • Power Limiter: +10%
  • Clock configured at Max 2900 MHz (yields ~2800 MHz)
  • Mem clock 2150 (=17200 Mbps effective)
  • FAN RPM default
The mem clock is limited to a maximum of 2150 MHz (17200 Gbps effective data-rate). We reached 2900 MHz on the GPU frequency. However, the power limiter kicks in, once it does downclock the card back mostly close to 2800 MHz when it gets GPU bound in a game. 


The results show respective default clocked results plotted in percentages. To the far right where you can see "Aver Difference %", this is the result of the four games tested and averaged out.
