Gigabytes B550M DS3H, AMD B550 motherboard - socket AM4 [B550M DS3H]

B550 mainboards support all 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 Gigabyte B550M DS3H at a glance:

1x PCIe 4.0 x16 (x16), 1x PCIe 3.0 x16 (x4) and 1x PCIe 3.0 x1
6x USB 3.0 / 6x USB 2.0
2x M.2 (1x PCIe 4.0 x4 and SATA / 1x PCIe 3.0 x4 and SATA) / 4x SATA 6G
DDR4 memory up to 4733 MHz using OC
Ready for AMD Ryzen 3000 processors

The equipment of the Gigabyte B550M DS3H in detail
The Gigabyte B550M DS3H is a micro ATX motherboard and has a PCI Express 4.0 slot with full x16 connection for graphics cards plus a PCI Express 3.0 x16 slot and a PCIe 3.0 x1 slot. The four RAM banks support up to 128 GB DDR4 RAM with a clock rate of up to 3200 megahertz and can even handle clock rates up to 4733 MHz via OC.

Two M.2 slots are provided by the AM4 mainboard. The slots are connected with four PCI Express lanes and accept plug-in cards up to 110 mm (22110). Both slots are also connected with the SATA-6G protocol. M.2 SSDs with the advanced NVM Express protocol (NVMe) and a connection via four PCI Express 4.0 lanes support data transfer rates of up to 8 GB / s and are twice as fast as via PCI Express 3.0.

Modern connections and RGB LED lighting
The Gigabyte B550M DS3H provides four USB 3.0 ports (blue) and four USB 2.0 ports on the I / O panel. An HDMI and a DVI-D 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 RTL8111G), on-board sound (Realtek ALC887 audio codec) and numerous internal headers. A special feature of the Gigabyte B550M DS3H are the three 4-pin RGB headers and two 3-pin RGB headers. Furthermore, up to three fans can be connected directly to the board.
