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.
Intel DP55WG mainboard is doing very well during CPU and memory overclocking and only falls behind all the other in “Image Editing” test again. This way, we can state that the defeat in this benchmark that we saw in the nominal mode for the first time is not an isolated incident. However, you shouldn’t be too upset about it, as the difference in results is not critical at all.
