![]() Next to default overclocking with added that added core voltage %, Nvidia came up with a new methodology as explained in the GPU Boost 3.0 paragraph on the previous page and our Pascal GPU related articles. So before we begin I like you to have a look at the AfterBurner screenshot above. GPU Boost 3.0 - Voltage/Frequency Curve TweakingĪbove Linear mode Curve tweaking (increase clock frequency with a relative but fixed offset in MHz). But the regular benchmarks are all hard on the GPU, the utilization, temp and power limiters will kick in and down-clock the GPU towards a scenario that remains stable. A more easy to render game will easily pass the 2.0 GHz marker, we've even seen 2.1 GHz. That Boost frequency will pretty much differ per game/application. Mind you that the 1950 MHz denoted is the clock frequency with the Unigine Heaven benchmark. This method is similar to the "basic" tweaking methodology we'll discuss in the next paragraph. Now with this overclock we have extra performance at our hands, as the boost clock will now work in the ~1.950 GHz marker depending on the power and temperature offsets. Fan control RPM fixed at 60% (a little more noisy but doable).ĭepending on the card quality (GPU leakage), ambient heat and other factors you might need to drop another 15~25 MHz on the core clock offset but from what I have seen, the example shown above, is very stable on founder edition GeForce GTX 1080 cards.Voltage +75% (voltage is now an offset percentage).Priority is set at power target and not temperature Target.Personally I am not a fan of this, but this is obviously by design from Nvidia. Fixed offsets like +80mV are a thing of the past. As stated on the previous page, the Core Voltage control is now based on the percentage of maximum voltage frequency. So make sure your PC casing is well ventilated with decent airflow.ĪfterBurner 3.0.0 (to be released) comes with GPU and memory tuning, overvolting, allowing control and adjustment parameters for overclocking.įor a regular (mild) tweak/overclock you could do something like above. That backside of your graphics card however gets hot as well, give it some airflow too. Cooling helps with overclocking, it's as simple as that. If you are willing to allow more noise, increase the fan RPM on the GPU towards a higher setting that you find comfortable. Once you get artifacts or a lockup, back down 25 to 50 MHz and typically that is your stable result in it's highest threshold - under the condition that the room temperature is the same (yes GPU heat and surrounding heat have an influence on your overclock). Related to heat is your graphics card cooling system. ![]() In the first stage you overclock your GPU, in the second the memory. ![]() First off let us remind you that we always recommend increments of roughly 25 MHz on core and memory (from the default base clock frequency upwards). When you want to overclock typically you need to verify and stabilize your tested settings. So before we begin to explore the new options, first this: the 'old way' of overclocking still is possible, in reality this would be what is referred to as basic mode, yet managed by the sliders that you guys all know and like.
