As a result our readers have differing levels of technical knowledge about a range of different things: today we are covering the field of graphics card overclocking. This article is aimed at a specific set of people, those who have little or minimal knowledge about graphics card overclocking, but we hope that even more experienced overclockers may be able to pick up a few tips or tricks from this article.Graphics Card Overclocking Guide Featuring The AMD Gigabyte R9 270 @ eTeknix
To the seasoned PC enthusiast graphics card overclocking is a self-explanatory term but for the casual PC user it may be an alien term, so what does it actually mean? In its simplest form it is about increasing the clock speed (which is measured in frequency) at which your graphics card operates. By default all graphics will ship with two different clock speeds: a clock speed for the graphics card's core (or engine) and a clock speed for the memory that the graphics card uses.These default clock speeds are referred to as stock speeds. The process of overclocking entails trying to raise any combination of those clock speeds above their stock level, whether that means the core clock, the memory clock or both. Hence the term overclocking is formed from the presumption that you will be clocking your graphics card over its stock levels.
That is of course a very basic explanation so we will bring more details in as we progress through this guide.
