Notes

We're testing the Gigabyte GA-Z77-UD5H in two ways. First off, we're looking at its stock-clocked performance against two other Z77 chipset-based boards. We expect the numbers to match up well to those previously reported for the cheaper MSI and Gigabyte offerings. Secondly, we're also showing numbers for the board running a mid-level overclock. We've increased the base speed of the CPU by 500MHz, as shown on the previous BIOS page, and increased the core clock of the iGPU from 1,150MHz to 1,400MHz. In both cases the CPU and iGPU voltage has been increased by 10 per cent. This mild overclock puts a slightly greater strain on the board's ability to run smoothly.

Full-on Overclocking

We've used exactly the same methodology to overclock the Core i7-3770K chip as with the two previously-reviewed boards. The toasty nature of an over-volted Ivy Bridge processor puts the onus more on the cooling than the smooth-as-silk power-delivery system of a motherboard. As such, with the same cooling in place, we managed to hit the same overclocked speed by manually overclocking the chip through the BIOS: 4.8GHz - 4.9GHz was stable for a few minutes. Benchmark performance, too, was within three per cent of these figures.
