As you can see from the image below showing the default settings for the GTX 750 Ti FTW ACX, the Power Target slider is set to maximum.

The card comes with a high factory overclock which sets the GPU base clock at 1189MHz, while the reference GPU base clock is set at 1020MHz. Nvidia's GPU Boost 2.0 takes the average GPU clock to 1085MHz for the reference GPU and to 1268MHz for the FTW card. The GPU clock offset slider can still be adjusted, so we tried it and using the standard voltage and AUTO fan settings we managed to push the GPU 90MHz over the factory clocks. The overclocking potential is very good considering that this is a factory overclocked card - and a relatively cheap one at that.

Memory overclocking is vital in any attempt to squeeze out more performance from a graphics card. Our memory overclocking run resulted with a total 150MHz (effective 600MHz) overclock.
