Overclocking the Gainward is as simple as all nVidia overclocking is these days, and whilst we don't get quite the extreme speeds we've seen from a couple of models it's still impressive with +120MHz on the boost making 1100MHz then the GPU Boost taking it right up to 1230MHz when under load plus we managed to get another 300MHz effective out of the GDDR5.
As a single card the cooler works very well, as there is plenty of room for the fans to suck cold air in and expel it out the sides. In an SLI arrangement though the temperatures quickly rise and the fans have to work harder, and therefore louder, to try and maintain the temperatures. We might even see a couple of scenarios where the GPU Boost 2.0 has to declock the card to keep things around the 80° threshold.
