Gigabytes B550 Aorus Pro AC, AMD B550 motherboard - socket AM4 [B550 AORUS PRO AC]

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 B550 Aorus Pro AC at a glance:
- 1x PCIe 4.0 x16 (x16), 2x PCIe 3.0 x16 (x2 / x4) and 2x PCIe 3.0 x1
- 2x USB 3.1 Type A / 1x USB 3.1 Type C / 5x USB 3.0 / 10x USB 2.0
- 2x M.2 (1x PCIe 4.0 x4 and SATA6G / 1x PCIe 3.0 x4) / 6x SATA 6G
- DDR4 memory up to 5200 MHz using OC
- Ready for AMD Ryzen 3000 processors
- With built-in Wi-Fi AC-3168 and Bluetooth 4.2
- RGB lighting

The equipment of the Gigabyte B550 Aorus Pro AC in detail
The Gigabyte B550 Aorus Pro AC is an ATX mainboard and has a PCI Express 4.0 slot with full x16 connection for graphics cards plus two PCI Express 3.0 x16 slots and two PCIe 3.0 x1 slots. 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 5200 MHz via OC.

The AM4 mainboard provides two M.2 slots. The slots are connected with four PCI Express lanes and accept cards up to 110 mm (22110). One slot is 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 GByte / s and are twice as fast as via PCI Express 3.0.

Modern connections and RGB LED lighting
The Gigabyte B550 Aorus Pro AC has a USB 3.1 port with type C socket, two USB 3.1 ports with type A socket (red), three USB 3.0 ports ( blue) and six USB 2.0 ports (type A) ready. The USB Type-C port can be plugged in on both sides, is particularly thin, and USB ports with this standard generally support the quick-charge function of smartphones and tablets. USB 3.1 reaches maximum speeds of 10 Gbit / s per port. An HDMI connection is available for CPUs with an integrated graphics unit.

Furthermore, this B550 mainboard offers features such as a WLAN / BT module, a 2.5 gigabit LAN port (Realtek RTL8125B-CG), on-board sound (Realtek ALC1220-VB audio codec), reinforced PCIe slots and numerous internal header. Also on Bo (a) rd are OC features, an optimized power supply and diagnostic LEDs.

A special feature of the Gigabyte B550 Aorus Pro AC is the RGB lighting, which can be synchronized with other RGB components using the manufacturer's software. The mainboard has three 4-pin RGB headers and two 3-pin RGB headers. Furthermore, up to eight fans can be connected directly to the board.
