Gigabyte Z87X-UD4H Review
At the risk of repeating ourselves we see the same disparity between the stock and overclocked results as we saw in CineBench. At stock the UD4H is the slowest system we've tested, even beaten out by the reference Intel motherboard. Yet with the overclock in place it's knocking on the door of the very fastest times. This certainly is one for the overclockers.

Another calculation-heavy test and another fastest and slowest result for the Gigabyte Z87X-UD4H. It's quite surprising to see such a mid-range motherboard perform so poorly at stock yet be so blistering once you've overclocked it.
