Hardware Asylum published The Different Types of Overclocking
A quote from the article:
Overclocking can be summarized into four different segments. Many of the segments overlap, which is part of the fun. First you have the Factory overclock. This is the type where you “buy” your level of performance and can be as simple as buying a Core i9 over a Core i7 or something more involved like picking up an EVGA RTX FTW that comes “hot clocked” from the factory and a special board design to increase stability.The Different Types of Overclocking
The next level is the casual overclocker and this really describes the person who buys the factory overclocked hardware but instead of running the hardware out the box decides to push things a little further. So that Core i9 they bought is now running overclocked and they enabled XMP on their 3600Mhz memory to support the two factory overclocked video cards they are running.
