ASRock A320M, AMD A320 motherboard socket AM4 [A320M]

The ASRock A320M is a motherboard in the micro ATX format and has graphics cards with a fast PCI Express 3.0 slot with full x16 connection. A PCIe-x1 slot is also available for other expansion cards. Up to 32 GB of DDR4 memory take up the two RAM banks, whereby corresponding memory can run with a maximum of 3,200 overclocked megahertz.

Special features at a glance:

1x PCIe 3.0 x16 for high-end gaming graphics cards
4x USB 3.0 Type A & 1x Ultra M.2 Slot PCIe 3.0 x4 & SATA-6G
DDR4 memory up to 3,200 MHz (OC)
Modern UEFI BIOS including temperature monitoring

Such as SSDs and hard disks, the board is managed by four SATA 6G connectors (including RAID support), as well as a horizontal M.2 slot, which is connected to four PCI Express 3.0 lanes, enabling enormous speeds up to To 32 Gbit / s. M.2 SSDs with a length of 42 to 80 mm can be used and the advanced NVM Express protocol, which has been especially optimized for highly parallelized data carrier accesses of modern PCIe SSDs, is supported.

On the mainboard rear, additional devices and components can be connected to the ASRock A320M via USB 3.0 and 2.0, Gigabit LAN, PS / 2 or three audio sockets for sound via the I / O shield. The internal connection repertoire includes a header for USB 3.0 for two ports and two USB 2.0 headers for four ports. The board also provides a TPM, COM port, and chassis intrusion header.
