I recently got a EVGA GeForce GTX 1060 SC ACX 2.0 and began overclocking it. I managed only to get it to +70 core and +130 memory, which is odd because with my GTX 1060 3GB, I could easily hit +180 and +465. When checking GPU-Z, it says the Core clock is at 1677MHz, and the Boost is at 1905MHz, The odd thing is, when I go into games or benchmarking software, the on-screen display says that the clock is hovering around 1980, and even pushing up over 2000 MHz, even though I haven't OC'ed it anywhere near that. Why is this happening? Is there some way I can control this (seemingly) random boosting?
 
Yeah that's GPU boost 3.0 doing it's magic, the official boost clocks are only the guaranteed clocks you'll hit. Anything above that is normal.

For a more technical explanation, GPU Boost 3.0 will auto overclock the GPU further if it sees there's enough power and temperature headroom. It'll back down once you hit your power limit and will gradually back down until the official boost clock depending on if temps get hot enough.

Then the actually base clock is guaranteed only if your thermal throttling.
