GTX 1080 Overclock
GTX 1080 Overclock
I own an Evga GTX 1080 gaming GPU that I recently purchased. My stable overclock with default stock settings at 120% would result in a +150 MHz core and 300mhz memory. Pushing further would introduce minor screen glitches, even at maximum voltage, where the core would reach +160mhz. Exceeding this would trigger similar artifacts. This seems to be a solid overclock.
Base core: 1607 MHz
Boost core: 1733 MHz
In-game it self-adjusts to roughly 1860-1886mhz without additional overclocking.

Don't increase the voltage threshold. It may gradually harm your card and reduce your maximum output capacity. This happens because of the power cap. Raising the voltage raises power consumption, pushing you closer to the 120% mark more quickly. This applies especially to Founder's Edition cards. I previously used an EVGA Founder's 1080, only tweaking Core and Memory offsets while keeping power and temperature limits at their maximums. My setup had a stable boost frequency of 2025Mhz and around 10.5Ghz overall for memory. On the other hand, my system was custom watercooled. Since you've already optimized fan curves, your performance is likely limited mainly by temperature. Keep in mind that GPU Boost 3.0 begins to affect this behavior.
Consider that overclocking has its boundaries... Different video cards offer varying levels of overclock potential, and numerous factors influence the outcome. My advice is to stay cautious—don’t push it or attempt it with a stable setup.
First, overvolting can damage your card.
Second, increasing the overclock raises temperatures significantly; ensure you have a well-cooled case and consider watercooling your GTX1080 for better OC potential.
Third, be aware that overclocking will also increase power draw from your PSU, which may affect both your power supply and your card’s health.
If the card already shows artifacts, further overclocking could cause additional harm.
Hi wuupman,
10XX cards feature GPU boost 3.0 that automatically increases core frequency under certain power settings and temperature conditions. You can revert the memory overclock, but it won't help with gaming performance.
What is the temperature of the card when fully loaded?

Don't try to increase the voltage limit. It may slowly harm your card and reduce your OC potential because of the power cap. This happens due to the power restriction. Raising the voltage raises power consumption, which could push you past the 120% threshold more quickly. This applies especially to Founder's Edition cards. I used an EVGA Founder's 1080 recently. I only changed Core and Memory offsets while keeping power and temperature limits at their maximums; I didn't adjust the voltage. In my setup, I maintained a stable boost frequency of 2025Mhz consistently, with overall memory performance at 10.5Ghz. On the other hand, my card was custom watercooled. Since you've already fine-tuned the fan curves, your temperature levels are likely near their maximum.
Keep in mind that GPU Boost 3.0 begins to reduce boost speeds once temperatures exceed around 58°C. That means boost will start to decline after that point. The lower the temps you maintain, the better the performance.
