It might be lacking the more obvious overclocking direction that the Sniper and Z87X-OC have but that doesn't mean that the UD4H isn't an eager overclocker. 4.9GHz is an excellent result and right at the limits of what we can attain on our i7-4770K.
One of the elements that has been, there is no other way to say it, dodgy on recent Gigabyte mid-range boards has been the vDroop so we're delighted to report that these issues have been fixed so comprehensively that the loadline calibration option has all-but disappeared from the BIOS and the overclocking stability is rock solid. Excellent.
With this dedication to ensuring good power delivery it's not surprising that the Gigabyte UD4H is one of the least power efficient Z87 motherboards we've tested, especially in the overclocked CPU scenario.
