If, on the other hand, you like living on the edge and you’re prepared to take some risk, it is still relatively safe to increase the card’s voltage to 1.25V with the stock fan (make sure you increase the fan speed though). 10% performance increase is still good and will give you a slight FPS boost in GPU bound applications and games… But… If you want to play it safe and / or you are afraid of tampering with voltage settings, leave it at that. Still, even with the stock fan and without increasing the cards voltage, you can still increase the core clock by at least 10%. With this being said, if you really want to play with the voltage settings (and by play we mean significantly increase them) in order to extremely overclock your HD 7000 series GPU, you should invest in some sort of an extreme cooling for your setup. Keep in mind that tempering with voltages can be pretty dangerous and you should only increase it slightly if you don’t have a proper cooling system for your GPU, and by “proper cooling system” we mean liquid cooling systems, dry ice (also known as DICE) and similar components. With this in mind, we will jump straight to business! You do not have to worry about this tutorial being too difficult to understand or just for “tweak geeks” overclocking is not as dangerous as lots of people claim it to be, especially if you know what you are doing and / or you have professional guide by your side (like this tutorial). With this being said, this tutorial will enable you to get the most out of your HD 7000 series graphic card without doing any significant damage to it. The cards in this series are quite durable, powerful but tend to overheat if you push them too much. This is exactly why a huge number of these graphic cards underwent extreme overclocking in order to reach their peak performance. Truth be told, this is especially true for the HD 7870 and HD 7970, both of which had amazing OC gaps and could be considered as overclocking paradise for enthusiasts. AMD’s HD7000 series of GPUs were a huge success not only because of their sheer performance but because of their huge overclocking potential at the time.
