Overclocking ability

As the sample doesn’t come with a cooler, we used the third-party cooler for test.

Default frequencies of GeForce GTX260 Extreme

Zotac GTX 260 Extreme comes with core/shader/memory clock of 750/1600/1200MHz, up from 576/1242/999MHz on the reference design.

Zotac GTX260 Extreme can be effortlessly overclocked to above 800MHz, and its performance can even outperform GeForce GTX285…

The awesome card is expected to be available in Chinese market next month, with lower pricing than GeForce GTX275. Zotac is also working on a GeForce GTX285 with 15 phase PWM design as well. We do look forward to seeing more of Zotac’s engineering skills in the future.
