Now let’s run the same tests with the CPU and memory overclocked. You can see the difference in the system parameters in the following table:
Since Gigabyte mainboard managed to overclock our test processor only to 4.3 GHz, which is 200 MHz less than the overclocking on most Asus mainboards, it is noticeably behind them in performance tests. Depending on the application, the performance difference varies between 2.3 and 5.3% staying on average at around 4%. If we compare the performance of Gigabyte GA-990FXA-UD5 against that of Asus M5A970 EVO and MSI 990FXA-GD80, which also failed to hit the maximum overclocking, the performance will be virtually identical. Even lower North Bridge frequency didn’t make things worse for Gigabyte mainboard. This aspect, as well as the memory sub-system settings doesn’t cast too much influence over the overall system performance.
