Gigabyte G1 gtx970 - Msi afterburner?

[Triforce]

What settings should I use for a stable overclock?

I currently have this since im not good with this.

Keep power limit at 110. Now, here's a guide I posted for someone who wanted to OC their SLI setup, so just ignore the parts that talk about SLI:

1. Download and install whatever graphics card OCing utility you like best. MSI Afterburner is usually the go to for people of the internet.
2. Download and install a benchmarking program like Unigine Heaven/Valley or Futuremark (Unigine Heaven or Valley are good and free; I recommend them).
3. Run the program in benchmarking mode and get yourself acquainted with how the visuals look. When testing your OC, you're going to have to make sure that no artifacts (graphical anomalies) occur.
2. In the OC utility, raise the core clocks on both cards incrementally (50 MHz should be fine to start, but as you go on, you'll want to use smaller increments).
a. For now, be sure not to enable the "Start PC with these clocks" (or whatever the specific term is) option. Once you achieve your desired OC, you can enable this if you want.
b. Also be sure to enable the option that synchronizes clock settings for all the same GPUs in your system.
3. Test the overclock with a benchmarking program. Be sure to monitor the temps of your cards while benchmarking. Also, make sure that you do not see any artifacts (graphical errors) on the screen.
a. For Heaven and Valley, you want to run through one benchmark for now (the program will show you how to do so).
4. If all's well with stability and temps, go back into the OC utility and raise the core clocks again.
5. Repeat step 2, 3, and 4 until you have instability. Instability could be shown through artifacts, the display cutting out, graphics drivers failing and maybe recovering, or a restart.
a. I tend to restart my computer every time I get instability to be safe. Sometimes it's necessary; sometimes it's not, but I'd rather play it safe.
6. Either lower the core clocks, or up the voltage (VDDC). Be sure not to use too high of a voltage.
7. Repeat steps 3 through 6 as desired.
8. Once desired clocks speeds are achieved, run the Valley/Heaven benchmark a few times through. You could also run the Futuremark benchmark a couple times (it's more taxing on a GPU than Heaven or Valley, in my opinion).

Now, for memory clocks, you want to do that same thing, but most OCing programs don't allow for the adjustment for the memory voltage (MVDDC), so you might not be able to get too much out of the memory.

I would also download HWiNFO. This program is very comprehensive, and if your graphics cards have VRM temp sensors, will allow you to check the VRM temps for both your core and memory.

Make sure to not let your GPU temps go above 95C (though you should probably keep them to 85C) and to not let your VRMs temps to get above 85C (though you should probably keep them around 75-80C).

And lastly, you might want to set a custom fan curve to ensure that proper cooling occurs.

Also, ignore the specific temps, as they were for a 780 Ti, but they should be relatively the same.
