How To Over Clock Your Graphic Card
How to overclock your graphics engine for optimal gaming experience...
Over clocking a desktop processor has long been a popular tweak for many tech geek’s, but with the rise of the gaming notebook generation, the trend is moving into the realm of overclocked graphics engines.
Overclock Your GPU
Many would assume the your average gaming notebook would already be geared for an optimal gaming experience. But the reality is somewhat different. Vendors will claim that the balance of speed, temperature and battery life, was painstakingly configured as a result of rigorous testing. In fact, if you were to examine the clockspeeds of your graphics hardware, you’ll often find it’s running far slower than is possible.
Tweaking your graphics engine is no easy task, the hardest part will be the cleaning of the notebook, and modifications you must perform on the graphics unit
We can not stress enough how important it is to thoroughly clean every component of your machine. Dust and dirt greatly affect the heat and performance of your machine.
Taking your laptop apart may turn out to be quite tricky. If you are lucky you maybe able to find an online guide for your specific model. If not you’ll have to proceed with caution. It maybe a good idea to jot down what you did at each stage, then reverse the process to make sure everything goes in the right order.
Clean Internal Components
Compressed air will get the job done quickly, but a good fashion blow and dust with a tissue should be sufficient. Remember the cleaner you can get you components, the smoother everything will work.
Because overclocking your graphics processor will generate more heat, it’s a good idea to get a laptop cooling pad, or replace your internal fans with more powerful ones. It is also advise that your replace the heatspread on the graphic processor with a more effective thermal paste.
This can also be tricky as the graphics will be encased with heatsink, you can use a firm but steady hand to prise open the seal. Once open you will see the thermal pad/heatspreader that interfaces with the cooling unit.
You need to peel off and remove all residue of the thermal pad, apply the thermal paste and reassemble the graphics unit.
Next you need to locate latest drivers for your particular graphics core along with the modified INF file from the appropriate site.
Once you’ve got them on your hard drive, unpack the drivers and then overwrite the original INF file that’s included in the reference drivers with the modified file you retrieved separately, before running the driver setup utility.
Instead of getting the usual message that there are no compatible drivers for your particular mobile hardware, you should just fly through the whole process without a problem and be rewarded with up-to-date drivers.
To check how hot your graphics chip gets, leave this on in the background and run a game for 15 minutes or so – hey, it’s work. Once you’ve finished, pop back out to the desktop and take a look at the Max value for your graphics card.
Overclock GPU With RivaTuner
Install RivaTuner and run it. Click on the Customize option under the Driver settings icon, hit System Settings and tick the Enable driver-level hardware overclocking checkbox.
Now you can push the clocks up slowly (10MHz at a time) until you get a stable overclock that actually produces a performance increase.
The test model was clocked from the initial settings of a 450MHz Core and 1064MHz memory clock all the way to 530MHz and 1248MHz.
