Overclocking your graphic card

Some basics ,before getting started

Why overclock your GPU?


The first reason may be to det more performance and to get a high score in 3DMark06 or other bench.
The secondly to forceits graphics card out to win some valuable FPS: a gain of 10 to 15% can be observed (and sometimes more!).
A third reason is to give a blow to its old graphics card or for instance to achieve the performance of the newer ones .

Warranty

I'll be honest with you overclock the GPU will void the warranty, without exception, even on models factory OC. A model factory OC is supposed to remain in that OC and not exceed it.

Cooling

Overclock a GPU causes an increase in consumption by the GPU and memory associated with it .
Therefore be sure to cool your GPU. Or, it can climb to 100 ° C over and stay at that temperature without too much damage, but the other components may suffer.
3 categories will therefore now be created:
So better integrate a Watercooling system.

Software

Before continuing this tutorial,you must have the following software:

RivaTuner
GPU-Z
FurMark
The overclock itself


First, open RivaTuner. Once open, click the little button next to "Customize", then select the first icon.
Activate the option "Enable driver-level hardware overclocking". Then just select the next profile Performance 3D.
You will find here an illustration.

First increase the frequency of the GPU 10 by 10. You can push 20Mhz higher than its original frequency. Then a good one-hour session of FurMark (Xtreme mode of course!). Be sure to check the temperature with "Temperature Log" located top right of the window FurMark.
Beyond 100 ° C, it stops and you lower the frequency.

Once the frequency of your GPUis found and its stability has been proven, do the same for memory, and always monitor its temperature, a temperature increase of memory increasing the temperature of the core same time.
Then, test the GPU and memory frequency up through five hours of FurMark still in Xtreme mode.
If your PC does not plant, you have succeeded!

A small detail: it is that the overclock depends on such factors as completely random:
- The quality of PCBs
- The purity of materials used to etch the core.
