The second comparison was performed during maximum processor overclocking. This time we disabled extended processor power-saving modes in the mainboard BIOS using “C-STATE” parameter, which limited the maximum processor clock frequency multiplier setting with 22x. In this case the CPU could work at higher base clock than with 26x multiplier, which meant that we ended up with higher resulting performance although it happened at the expense of higher power consumption in idle mode. During the performance tests with overclocked CPU and memory the boards were also split into two groups. Only Gigabyte mainboards and Asus P7P55D Deluxe could overclock our processor to 3.95 GHz, while all others stopped at 3.9 GHz.
As you can see, the situation has changed completely during overclocking. Gigabyte GA-P55M-UD4 mainboard is at the top of the performance charts and even takes the lead once. But if we look at the actual numbers one more time, we will see that there is nothing extraordinary about its results: it demonstrates normal performance level for a system with overclock processor and memory. So, overall, the performance of Gigabyte GA-P55M-UD4 mainboard in nominal mode as well as during overclocking doesn’t really surprise us: it is at about the same level as by other mainboards.
