After finishing up our DDR4 memory scaling article on an AMD Ryzen processor with an AMD X370 chipset powered board we were left wondering if memory performance and scaling was similar on different AMX X370 motherboards from different manufacturers. We gathered up the MSI X370 XPOWER GAMING TITANIUM ($299.99), GIGABYTE GA-AX370-Gaming 5 ($194.99) and ASUS ROG Crosshair VI Hero ($254.99) motherboards as the three boards that we were going to try out. Looking at the 'big 3' motherboard markers should give us a pretty good idea if there are any big differences to be had with regards to the memory subsystem.
