When considering where this fits in the Gigabyte line-up you can usually get a fair indication by the number. Of course there doesn't appear to be a UD7 on the horizon, and this is a UP rather than UD, but it still fits neatly into the gap between the D3H and the UD5 when it comes to overclocking our i7-3770K. Although we saw 4.8 GHz able to complete most runs, it wasn't completely stable in all of our testing and so we settled on 4.7GHz for our overclock tests today.
Considering the efficiency and cooler running that was lauded by the IR3550 MOSFET, it's slightly disappointing that we didn't see a higher usable overclock. One of the side benefits to the cooler running of the IR3550 is that the area around the CPU is cooler, which can make a slight difference in your CPU temperatures. During testing we found that on average our Core i7-3770K was 3°C cooler than it usually is. Not an earth shattering change, but any reduction in thermal profile has to be appreciated. It might, if you're running a lesser CPU cooler, make enough difference to allow you to achieve a higher overclock.
