Next Page Benchmarks: Crysis 3, BioShock. even cooling solution and your chassis airflow. Our results showed the GeForce GTX 970 to be in line with the R9 290X for example. The end result depends on a lot of variables though, including power limiters, temperature limiters, fill-rate and so on, the performance increment can differ per card, brand, heck. Despite featuring 27 less transistors in a 29 smaller die using the same 28nm. Overall the generic rule of thumb here for a decent tweak and overclock is that performance can gain anywhere from 5 to 20% performance. Mid-way through September Nvidia unleashed its Maxwell-powered GTX 900 series with the GTX 970 and GTX 980. The Samsung GDDR5 memory used can run at 8 GHz (effective data-rate).įor all overclocked games above we have used the very same image quality settings as shown before. The GPU will continuously be dynamically altered on voltage and clock frequency to match the power and temperature targets versus the increased core clock. The boost clock will now render at roughly 1501 MHz depending on the power and temperature signature. tweaking GPUs is at your own risk! Original GTX 970 Look carefully and observe well.Īll in all. Carefully find that limit and then back down at least 20 MHz from the moment you notice an artifact. Usually when you are overclocking too hard, it'll start to show artifacts, empty polygons or it will even freeze. Usually when your 3D graphics start to show artifacts such as white dots ("snow"), you should back down 25 MHz and leave it at that. More advanced users push the frequency often way higher. 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. 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. It sounds hard, but it can really be done in less than a few minutes. Overclocking: By increasing the frequency of the videocard's memory and GPU, we can make the videocard increase its calculation clock cycles per second. We can really recommend it, download here. ![]() 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. Typically you can tweak on core clock frequencies and voltages. As most of you know, with most video cards you can apply a simple series of tricks to boost the overall performance a little.
