I am just starting with GPU overclocking and finally succeeded. I achieved a +150 core clock boost and +400 on memory without increasing the voltage, and the power limit is at 110%:

I ran some benchmarks for Heaven, Valley, Furmark, and played Witcher on ultra 1440p. When playing Witcher 3, the GPU kept using around 103-107% power, but the maximum it reached was 115%:

Is this typical? How does this happen? Is my overclock stable? All games and tests are running fine.
Thanks in advance!

Using my 980ti with a 110% power cap keeps it stable, but with the modded bios, I push it to around 200%. As long as the cooling is sufficient, the card won’t overheat even if it runs at higher limits. It will just get warmer because more current flows through it.

Surpassing the power limit is typical. Increasing overclocking consumes additional power.

Exceeding the power limit is typical. Increasing overclocking usage consumes additional energy.

Using my 980ti with a 110% power limit keeps it stable, but with the modded bios, I can push it to around 200%. As long as the card has solid cooling, exceeding the limit won’t cause major issues—it just makes the card run hotter due to increased current flow.

Open GPUz to the sensors tab and observe the "PerfCap Reason" line. If green "PWR" appears in that line during your runs, it means you're reaching the power limit defined by the perf cap.
