The GPU overclocking is getting popular these days.The VGA card producer like ASUS,Gigabyte and MSI have introduced their overclock-able graphics cards to the market.So this GPU overclocking can improve your gaming performance up to a certain level.
GPU overclocking can't turn your GT610 or low profile VGA into a Titan.But it can improve the FPS rate of your game.And there are some card which cannot be overclocked.

GPU overclocking may void your warranty.I will not take the responsibility for any damage which can happen to your cards.Do at your own risk.
Things You need for GPU overclocking
- An overclocking software like MSI afterburner , EVGA precision or Riva Tuner.If you have a AMD graphics card you don't need any software you can use Catalyst Control Panel.
- Download MSI After burner
- Downoad EVGA precision(You need to create a free account)
- Download RIVA tuner(Windows 8 not supported)
- A benchmark software like 3D Mark , Heaven etc.
- GPUZ video card information sotware.
- If you're trying to hit extreme clocks a third part cooling system for your graphics card.
Now open GPUZ and write download memory brandwidth,Pixel Fillrate , Texture Fillrate at its default clock.
Now Open Benchmark software and start benchmark.I prefer Heaven.You can use any preset.If you don't have a high end card it is better to use a medium setting.
Now write down the max FPS and min FPS during the benchmark.
Open your overclocking software.And run the benchmark again while it is opened.Increase memory clock by 5MHz steps.You should keep a time gap between these steps.
While you're increasing the memory clock check for any artifacts.If you see any random pixel sized multi coloured dots in the screen it means your memory is a little bit stressed.Reduce memory clock two or three steps until you don't see those artifacts on the screen.
Now write down the maximum memory clock you can use without getting artifacts.Now let's move to the GPU clock.Follow the same steps above.Decrease clock when you see artifacts.You should keep an eye out for GPU temperature.It's good to keep the GPU temperature below 80 C as most of the graphics cards have max GPU temperature around 90 C.
You can use GPUZ to check whether the increments of your graphics card's memory and GPU clocks have applied.Because some GPU overclocking softwares cannot overclock some cards.

Look at the snapshot above.EVGA precision cannot overclock memory speed on a NVIDIA GT8600 Gigabyte.Although it shows Mem Clock Offset +68MHz has applied it hasn't really applied on the card.
Now after finding the maximum memory and GPU clocks for your card apply them at once.Run the Heaven or 3D mark again.Check for any artifacts on the screen.This is the GPU overclock stability test.If you see some decrease both memory and GPU clocks until you don't see any artifacts.When you are finished run a benchmark and compare the results you got at first.
Even a 5 FPS increment may make a huge difference in your gaming experience.It can turn an unplayable game into playable.You should have FPS between 25-35 at least to play a game without any lag.In multiplayer games the FPS count is very important.In multiplayer shooter games you need at least 60 FPS to use sniper rifles like a pro ;).
You can add heatsinks for memory chips of the graphics card.Search memory heat sinks in online stores like eBay , Amazon.They are very cheap and they will stabilize your overclocks and give your card a longer life.
If you need to go for a extreme overclock like 500MHz ,you need to increase the memory and GPU voltage a little bit.It is a very advanced process and first you need to find the max voltages for your card.If you apply a higher voltage than the maximum voltage your card can handle you may brick it.
