GTX 1070 Overclocking

[Havel]

Out of curiosity, what's the best overclock have some of you been able to get on the 1070. I haven't started overclocking mine yet but i'm wondering what i should be shooting for.
Edit: i have the 1070 SC

Every GPU overclocks differently so we don't have any recommended OC'S set in stone.

 

Watch this:

Best I have gotten on my MSI 1070 Sea Hawk EK X:

 

+150 on Core Clock

+900 on Memory Clock

 

This ran successfully Heaven Benchmark but some games it will artifact.  Card was running about 70 top on Water Cooling

I have settled on a lower clock for my gaming and every day usage.

 

+125 Core

+750 Memory

With these my card doesn't go above 60C.

as @LinusTechTipsFanFromDarlo said, watch the video. But as a owner or 1070, I reckon you'll get your a little over 2ghz. Usually 2088 is the point where it starts with artifacts. Mine does 2065. You see what you get. It's a noticable improvement, since you're pushing it 10% faster.

Don't expect huge gains by manually overclocking. GPUboost 3.0 already automatically overclocks all these cards significantly higher than what they are listed to run at (base/boost). My Founders runs in the mid/high 1800's without touching a thing and low 2000's / high 1900's with manual overclocking. So a 200MHz boost from manual overclocking might not seem like much, but consider the stock boost clock is supposed to be 1683, that puts it more in perspective.  

 

The clocks are tied directly to temperatures, so the cooler you can keep the card, the higher clocks it will sustain. Creating a custom clock vs voltage curve will yield slightly better overall performance compared to just moving the clock offset sliders. 

 

Oh and the memory on most 1070's can easily go to 9000MHz.

The offset values for the core clock means nothing. The actual core clock speeds achieved are not +(offset value) above the rated base/boost clocks. 

 

What are the actual core clocks you observe and maintain while gaming?

Also, just to add another tip; adding voltage will not necessarily yield better performance. In my experience with the Founders card, adding voltage did nothing for increasing clocks but only made the GPU run hotter, (which in turn, reduces clock speeds). 

 

Overclocking Pascal and GPUboost 3.0 has made things much more complicated with regards to overclocking. Everything is tied together and it's a matter of achieving a good balance of offset at specific voltages while keeping the card running as cool as possible. It's area under the curve that determines performance, not peak clock speeds.

I've added 50% core voltage to mine and have noticed a slight performance improvement.

Oops you are right I wasn't thinking.  Stable clocks are:

Core 2100Hz

Memory 9400Hz

 

Maxed out I think i got 2133Hz and Memory 9800Hz.

That may be the case with non-reference (non-founders) cards as they have better cooling. It requires quite a bit of time and patience (and trial and error) to really dial them in with GPUboost 3.0 trying to optimize everything at the same time.
