And now let’s run the same exact tests in overclocked mode, when both - processor and memory – work at higher frequencies. Remember, that Gigabyte GA-P67A-UD4-B3 overclocked our processor only to 4.7 GHz, on Foxconn P67A-S we forced overclocking without the increase in the processor Vcore, so we had to stop at 4.5 GHz, while on other mainboards the CPU frequency was increased to 4.8 GHz. The system memory worked at 1600 MHz with 6-6-6-18-1T timings on all testing participants except Micro-Star P67A-GD80 (B3). Here the memory frequency was increased to 1867 MHz and the timings were set at 7-7-7-20-1T. The table below shows the differences in system settings for each testing participant very clearly:

Once again, there is barely any performance difference between the boards that managed to overclock the CPU to 4.8 GHz, with the exception of the notorious 3DMark 11 test. However, higher memory frequency puts MSI P67A-GD80 (B3) at the top of the list most of the times, which makes it seem like an indisputable leader of this test session. In fact, we already know from our previous article called “DDR3 SDRAM for Sandy Bridge: Choosing the Best Memory for LGA1155 Platform” that higher memory frequency does have a positive though not very dramatic effect on the system performance.
