As most of you know, with most video cards you can apply a simple series of tricks to boost the overall performance a little. Typically you can tweak on core clock frequencies and voltages.
What do we need? One of the best tools for overclocking Nvidia and AMD videocards is our own AfterBurner which will work with 90% of the graphics cards out there. We can really recommend it, download here. We used Precision for now though as AB still needed some work at the time of writing this article.
Where should we go? Overclocking: By increasing the frequency of the videocard's memory and GPU, we can make the videocard increase its calculation clock cycles per second. It sounds hard, but it really can be done in less than a few minutes. I always tend to recommend to novice users and beginners, to not increase the frequency any higher than 5% on the core and memory clock. Example: If your card runs at 600 MHz (which is pretty common these days) then I suggest that you don't increase the frequency any higher than 30 to 50 MHz.
More advanced users push the frequency often way higher. Usually when your 3D graphics start to show artifacts such as white dots ("snow"), you should back down 10-15 MHz and leave it at that. Usually when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Carefully find that limit and then back down at least 20 MHz from the moment you notice an artifact. Look carefully and observe well. I really wouldn't know why you need to overclock today's tested card anyway, but we'll still show it.
All in all... do it at your own risk.
Core Clock: 863MHz
Core Clock: 889MHz
Core Clock: 1034MHz
Boost Clock: 906MHz
Boost Clock: 941MHz
Boost Clock: 1215MHz
Memory Clock: 6008 MHz
Memory Clock: 6008 MHz
Memory Clock: 6732MHz
To get the tastebuds going here's an example of what you can achive with a tweak or two. We applied:
Power Target 110%
Priority at Temperature target
Temp Target 95 Degrees C
CPU clock +145 MHz
Mem clock +360 MHz
Voltage +37 Mv
With this overclock we have extra performance at our hands, as the boost clock will now render at 1175~1202 MHz depending on the power and temperature signature. The GPU will continuously be dynamically altered on voltage and clock frequency to match the power and temperature targets versus the increased core clock. Have a peek at the results when overclocked.
For all overclocked games above we have used the very same image quality settings as shown before. Overall we have been able to get another 5% to 10% performance out of those graphics card.
ASUS GeForce GTX 780 Ti DirectCU II OC review We review the ASUS GeForce GTX 780 Ti DirectCU II OC edition. Customized GeForce GTX 780 Ti graphics cards are a hot thing these days, as they are silent, running cool and offer tremendous rendering ...
ASUS GeForce GTX 760 DirectCU Mini review In this article we review ASUS GeForce GTX 760 DirectCU MINI edition, this particular model comes with a dual-slot DirectCU Mini cooling solution that will fit small form factor based motherboards like Mini ITX up-to 17cm. ASUS has re-engineered the DirectCU cooler to fit small form factor cases. While shorter, it introduces a copper vapor chamber placed directly on top of the GPU for faster heat spreading and dispersal with lower temperatures than reference GTX 760.
ASUS GeForce GTX 760 DirectCU II OC review In this article we review ASUS GeForce GTX 760 DirectCU II OC edition, this particular model comes with a dual-slot DirectCU II cooing solution. That boils down to a silent product versus and more than excellent cooling performance. Inno3D offers the card factory slightly overclocked at some pretty impressive clock frequencies.
ASUS GeForce GTX 780 DirectCU II OC review We test and review the ASUS GeForce GTX 780 DirectCU II review edition. The graphics card comes with a factory overclock and an updated DirectCU II cooler that has CoolTech fans. That would be two silent 90mm fans.
