Overclocking Results

Overclocking NVIDIA’s Kepler architecture can be a complicated process since it includes modification of Power Limits, clock speeds and Boost offsets. However, that shouldn’t dissuade anyone from trying to get the most out of their GTX 660 Ti.

For these tests, we used ASUS’ excellent GPU Tweak EVGA’s Precision, MSI’s very popular Afterburner and Galaxy’s little known but highly capable Xtreme Tuner Plus. Unfortunately, Gigabyte still doesn’t have their own overclocking utility so we ended up using Afterburner to overclock their GTX 660 Ti OC.

In all cases we added 100mV to the core and GDDR5 while MSI’s Power Edition was the only card to support a 50mV bump in PLL voltage as well. As with all other Kepler-based overclocking experiences, we set the Power Limit to the absolute maximum while the fans were left at their default speed. All results are considered 24/7 stable.

As we can see, ASUS’ TOP edition wins this section hands down. It seems like they have built higher power limits into their card which allows it to Boost to extremely high frequencies when given enough voltage. The products from MSI and Galaxy are extremely close behind while EVGA and Gigabyte bring up the rear.
