German overclocking guru der8auer recently published a video tutorial that covers the Nvidia GTX 1080 Ti card. Unlike many of his previous videos which focus on applying voltage mods or other kinds of modifications for extreme overclocking, this video takes starts at the very beginning of the overclocking journey - honing in on exactly how to get the most from the new Pascal GPU using stock air cooling.
The rig used in the video features a Founders Edition GTX 1080 Ti card mounted on a Broadwell-E system that features an Intel Core i7 6950X chip pushed from its stock settings of 3GHz to a nice 4GHz overclock. The deca-core processor is mounted on an ASUS Rampage V Edition 10 motherboard with 32GB of G.SKILL DDR4 memory.
Roman kicks off proceedings by offering advice about finding out exactly what the capabilities of your GPU really are – not all GPUs are equal of course, so discovering the frequency, clock and thermal limitations of your card is essential to finding the outer limits of stable performance. He begins by using MSI Afterburner to check out the card’s configurations at idle during non-3D tasking. The MSI Afterburner app shows real time GPU clock and voltage levels. He then uses the GPU-Z render test to do push the car into 3D mode to see the upper values of the GPU when clocks are boosted. Roman goes to explain how he used the new Unigine Superposition benchmark to establish an effective, real-time stability comparable to any gaming scenario.
The video is a great introduction to overclocking an air-cooled GPU, as ever presented in a well thought out logical step-by-step fashion. You can find the tutorial video from Roman here on the der8auer YouTube channel.
