Rinse and repeat until you have nothing left to give. I use Unigine Valley for this 'quick OC'ing it will crap out fast if you overdo the core clock and has very consistent scores, so you can quickly identify if its worth to keep pushing.Īs soon as you hit instability (frequent stutter, artifacting, or lower scores), add +10% to Power Target. If that sticks work from there and use +20 steps on Core, rebench and see if you still gain performance (= points!). On STOCK voltage and power target, you can start with +100 Core and +500 Mem. You should be getting an extra Ghz out of it usually for VRAM. 1070ti benefits a lot from memory OC, especially in min. No extensive tweaking involved, if you have good temps, knock the slider for extra core volts to the right and start testing clockspeeds. While temperature is key, there is still a hard limit which is voltages. (13-39 mhz, simply because you can hold your boost bins a bit better) The gain however is going to be extremely limited over a 'simple' overclock. If you want to push it, especially on air, this is what you need to be tweaking with. EVGA's Precision X offers a fine grained OC control that allows you to set a voltage for every temperature target. The peak is nice for benches, but that's it. Your real OC is actually thát clockspeed. With my 2100 mhz peak setting, I do drop down all the way to 2000mhz because of temperature over time. In the end, a high OC is only worth it if you can keep it going. Because its so temp sensitive, lower voltages may offer better sustained clocks. Temperature is therefore a huge factor in what you can hit. It starts dropping 13mhz 'boost bins' at every 5 C interval from I believe 55 C onwards. The real key to Pascal overclocking is getting familiar with GPU Boost: 2000 mhz however should be in the cards for almost every Pascal GP104. Now, the 1070ti is a cut down chip and not a top bin part so it may be different, but as always YMMV. I've had 2138mhz stable on an EVGA GTX 1070 and I have 2100 stable (peak) on my current GTX 1080.
