Overclocking Results


As we discussed on the previous page, overclocking the GTX 670 is straightforward if you can come to grips with Boost clocks. Using EVGA’s Precision X application, we were able to easily hit performance levels that bested a GTX 680.

Unfortunately, we were somewhat held back by NVIDIA’s TDP limit (even with it maxed out in Precision) since once we hit a Boost level of around 1259MHz, performance hit a plateau with the core refusing to increase its in-game speeds any higher. Nonetheless, these are excellent results. The memory actually did quite well too since it stopped returning performance increases (likely due to error correction stepping in) at 6468MHz.

This situation actually brings up an important fact about overclocking Kepler-based cards: even though you can increase the core’s frequencies to your heart’s content, the in-game clock speeds may in fact be LOWER than your intended setting. As such, a simple GPU-Z screenshot of your “achievement” may not prove anything and this is why all of our stated overclocks have been thoroughly tested in-game.
