I watched some YT video's and did what was recommended for beginners.

Core Voltage : 100%
Power Limit: 120%
Core Clock: +200 (Error)
Memory Clock: +400/500/600 (Error)
Fan Curve: Check
Fan Speed: 65%

Soo after some lag spikes and crashes (Never artifact issue's) in Valley Benchmark i went on putting it down slowly to:

Core Voltage : 100%
Power Limit: 120%
Core Clock: +150
Memory Clock: +350
Fan Curve: Check
Fan Speed: 65%

This works well and no crashes or any other weird things. After this i went to test a couple more things.

Core Voltage : 0%
Power Limit: 115%
Core Clock: +150
Memory Clock: +350
Fan Curve: Check
Fan Speed: 65%

This gives me the same result as the past one. (Both tested for atleast 1hr)

My thing here is: Why can't i overclock further? Because these settings also work with 0% Core Voltage. Shouldn't that extra Core Voltage give me more space in overclocking?

Overclocking is safe as long as you're sure its stable.

Graphics cards, specially Nvidia's cards, are pretty locked down to what you can do to overclock them, so any setting you manage to make work should be perfectly safe for the card as long as the...

Core voltage and Power limit should always be set to their maximum if the temperatures allow for such (If you're not hitting over 80ºC you should be fine), however, you should begin by overclocking the memory first or the GPU first, to see what gives you the best results.

If you start by overclocking the VRAM (memory clock), increase it in 25 segments until it goes unstable (usually 1 minute of valley shows if you're unstable or not as a rough measurement, if increasing more clock crashes, then you try the previous setting to further test if it was stable), you can start with what you have which is 350Mhz on the VRAM. Put the GPU core to 0 and then try increasing the VRAM more and once you've hit a wall, back off in 25Mhz steps again until you get it stable, then proceed to start increasing the GPU clock by 25Mhz increments until you can't get it stable anymore, then back off to a stable setting.

Benchmark and see what you get, then try doing the opposite and increase the GPU clock as much as you can and then once you hit a wall, work the VRAM frequency until you get it to its maximum stable clock, and benchmark again.

I'd start with the ladder and overclock the GPU first, and then based on your results, see what is best for you and go with it.

I say this because memory clocks have stopped me from increasing GPU clock in the past because I overclocked both at the same time, clocking the GPU higher and the Memory lower can wield you more FPS in certain cards, I'd like to give you the straight out answer but I don't have nor have I played with a GTX 1070, trial and error is the best policy as not all GPUs nor memories clock the same.

Hope this helps!

I did what you said. I can get +200 on core that way and + 400 on memory. When i benchmark that it performs worse then the +150 / +350 setting. My temps are fine, the max temp i get is 70 Degrees. I try to see if more clock less memory speed works better.

Overclocking is all about finding the sweetspot. Keep trying till you get the best setting for your needs.

I have 2 other questions.
Is overclocking safe to do these days?
What should be fine for a 24/7 overclock?

Overclocking is safe as long as you're sure its stable.

Graphics cards, specially Nvidia's cards, are pretty locked down to what you can do to overclock them, so any setting you manage to make work should be perfectly safe for the card as long as the temps are within safe limits. No worries.

I came down to these settings +150 core +400 memory. My temps are fine and i don't see weird things happen. Tested with different benchmarks Valley Bench, 3D Mark, RealBench. I am working on my CPU aswell.. But i think the cpu is pretty irrelevant since it doesn't gain that much.
