Overclocking Potential

We set the Power Limit to the maximum which was 123% for our Zotac GeForce GTX 660 Ti 2GB.

Keeping GPU voltage intact, we overclocked the GPU from its default 928 MHz by 135 MHz. We also overclocked the memory chips by 1160 MHz:

The resulting GPU and memory clock rates were 1063 and 7168 MHz, respectively.

That’s good enough but what about temperature? How hot is the card now?

78°C with the fans working at 2700 RPM. We don’t know how this compares with the reference GeForce GTX 660 Ti and its cooler and we don’t have other brands’ GTX 660 Ti cards as yet. We can only add that we couldn’t reach higher clock rates after increasing GPU voltage.
