We decided to use the popular i5-750 CPU for our testing as it should give us a good idea of the overclocking potential of the H55M-UD2H motherboard. This was cooled by a CoolIT ECO A.L.C CPU cooler installed into a Corsair Graphite 600T chassis.

All the latest bios updates and WHQL drivers are used during testing. We perform under real world conditions, meaning KitGuru test all games across five closely matched runs and average out the results to get an accurate median figure.
For our tests, we overclocked the system to 4.00GHz using a base clock of 200MHz with a multiplier of 20x. We were able to push the system to 4.20GHz but encountered stability issues in some of our more demanding tests.
