WHAT IS OVER-CLOCKING??
You can increase the clock speed of card upto 25% of the original and this varied from card to card.
- Overclocking does increase a noticeable performance in games but it’s a risky process that voids manufacturer’s warranty, so do it when you have no warranty left or you badly need some extra performance increase in the latest games.
- Also make sure that you have adequate Power Supply for your rig and for your Graphic Card as less power may lead to short-circuiting and damaging your hardware.
- Cooling is very important as well so have a good cooling system installed with a good cabinet for proper room and air-flow.
HOW TO DO IT??
This is used only for Nvidia cards and will not support AMD/ATI manufactured cards!
Also make sure to install the latest drivers for your graphics card.
Overclocking the GPU Core
Overclocking the Video Memory
Hope that you find this article helpful, I'll post another article for AMD/ATI card users soon though it also follows the same process but with the AMD Catalyst Vision software that comes along with the cards itself.
Feel free to post your queries and suggestions for further improvements.
