ASRock B550M-HDV, AMD B550 motherboard - socket AM4 [90-MXBDJ0-A0UAYZ]

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.

The features of the ASRock 550M-HDV at a glance:

1x PCIe 4.0 x16 (x16) and 1x PCIe 3.0 x1
6x USB 3.0 (internal & external) / 6x USB 2.0 (internal & external)
1x M.2 (1x PCIe 4.0 x4 & SATA) / 4x SATA 6G
DDR4 memory up to 4600 MHz using OC
Ready for AMD Ryzen 3000 processors

The equipment of the ASRock 550M-HDV in detail:
The ASRock 550M-HDV is a micro ATX mainboard and has a PCI Express 4.0 slot with a full x16 connection for graphics cards. The motherboard provides a PCIe 3.0 x1 slot for additional expansion cards. The two RAM banks support up to 64 GB DDR4 RAM with a clock rate of up to 3200 megahertz and can even handle clock rates up to 4600 MHz via OC.

An M.2 slot is provided by the AM4 mainboard. This is connected with four PCI Express 4.0 lanes, accepts plug-in cards up to 80 mm (2280) and achieves a maximum data transfer rate of 64 Gbit / s. M.2 SSDs with SATA connection are also supported here. In addition, the ASRock 550M-HDV provides four SATA 6G connections.
Modern connections and RGB LED headers
The ASRock 550M-HDV provides four USB 3.0 ports with a type A socket and two USB 2.0 ports on the I / O panel. An HDMI, DVI and VGA connection are available for CPUs with an integrated graphics unit such as AMD's Picasso APUs.

Furthermore, this B550 mainboard offers features such as a gigabit LAN port (Realtek RTL8111H) and on-board sound (Realtek ALC887 audio codec). Furthermore, four fans can be connected directly to the board.
