Performance - DDR4 System Memory
Performance System Memory: Memory Read Test
Intel Coffee Lake supports dual-channel memory. While Intel officially supports up-to 2400 MHz DDR4, most Z370 motherboards will support XMP memories in the 4 GHz domain.
Above is a test at 3866 MHz, however we are giving the AMD Ryzen platform the advantage of 3200 MHz memories, we do the same for Intel and thus test at 3200 MHz. We moved all processor testing to 3200 MHz, both for AMD and Intel for fair play and same platform investment cost. Above, simply an example of XMP 3866 MHz being run on this motherboard.
