Overclocking & Noise
Overclocking and noise
The GTX 1070 Ti, like the GTX 1070 and the GTX 1080, are very quiet cards even when overclocked. NVIDIA guarantees a minimum Base Clock of 1607MHz and an average Boost of 1683MHz for the GTX 1070 Ti. At stock, we actually got a sustained 1809MHz Boost as long as the GPU stayed below 84C.
We settled on a preliminary core offset of +200MHz with +400MHz added to the memory clocks. This is still a preliminary overclock that will be fine-tuned in a follow-up evaluation when aftermarket Vega 56 cards are released. However, we did compare 10 games at stock versus overclocked settings, and the overclocked GTX 1070 Ti caught or surpassed the GTX 1080’s stock performance, and it also matched or beat the stock Liquid cooled Vega 64 in many cases.
Although we never adjusted the voltage, we set the Power and Temperature targets to their maximum (120% and 92C). We used an automatic fan profile for all of our stock benching, but increased the fan rpm up to its maximum when we overclocked to keep the GPU cool. Here are are our results after looping Heaven 3.0 continuously with the temperature settling in below 70C with the fan at 100% at maximum overclock. The ambient or room temperature was warm in the upper 70s F.
Our maximum sustained boost is 2050MHz and higher when the GPU is kept cool below 65C, but it drops to about 2025MHz when temperatures approach 70C. The voltage was kept at stock, but the average locked-on core clock remained above 2000MHz and our memory clocks stayed at 4404MHz.
Temperatures did not exceed 84C at any point with the stock fan profile although throttling began to occur at this temperature while we were overclocking. The fan becomes noticeable at 65%, but it is not annoying at even 100% as it is more of a “whoosh” of air and there is no whine nor any irritating sound.
Let’s check out the performance charts where we also show GTX 1070 TI FE overclocking results.
