B550 mainboards support all the features of the Ryzen processors of the third and fourth generation, especially the PCI Express standard in version 4.0 (PCIe 4.0). PCIe 4.0 is backward compatible and can be used with all expansion cards from previous generations. In addition, the mainboards support up to 128 GB of RAM with a guaranteed clock speed of 3200 megahertz. With overclocking, much higher clock rates are possible depending on the mainboard. The B550 chipset also enables the processor to be overclocked.
