The memory bandwidth performance was as expected when testing with AIDA64 Extreme Edition as all five P67 motherboards produced similar results. All boards were tested with the same DDR3-1600 memory which was manually set to the same CAS8-8-8-20 timings.

Interestingly the only motherboard to show slightly weaker L2 Cache performance was the Asrock P67 Extreme6. Given that this test should only focus on the CPU it is strange how the Asrock board was consistently slower here.
