Gigabyte Z77X-UD5H Motherboard Sandy Bridge Review

Overclocking was something we were really keen to look into, as we wanted to see what the Z77 chipset had to offer with our i7 2700k Sandy Bridge processor as we already knew what it was capable of on a Z68 platform.

We started to push the multiplier from 4.6 to 4.8 and then on to 5GHz. Things were looking hopeful when we wanted to push the overclock even further and 5.2GHz was in our sights. We managed to hit that sweet spot of 5.2GHz, but anything above that was a no go area.

We tried to increase the multiplier to 53, but no matter what voltage we chucked at the board, it wouldn’t go above 52. Our next choice was to increase the bus speed, but that also seemed to be stubborn and wanting to stay at 100MHz leaving us with a final overclock of 5.2GHz.

CPU-Z being CPU-Z decided not to show the true voltage, but we recorded the voltage at 1.528 due to the fluctuation of the voltage once the CPU had been loaded. All in all, a great overclock was had from this board, and could end up rivalling some higher-end boards on the market.
