MSI A320M Grenade, AMD A320 motherboard socket AM4 [7A39-003R]

The MSI A320M Grenade is a motherboard in the Micro ATX format and has graphics cards with a fast PCI Express 3.0 slot with full x16 connection. Furthermore, two PCIe-x1 slots are available for other expansion cards. Up to 32 GB of DDR4 RAM take up the four RAM banks, with corresponding memory running at a maximum of 2.666 megahertz. The internal connection repertoire includes a header for USB 3.0 and two for USB 2.0 for two or four ports, respectively.

Special features at a glance:

1x PCIe 3.0 x16 for high-end gaming graphics cards
6x USB 3.0 / 6x USB 2.0 / 1x Turbo M.2 slot PCIe 3.0 x4
3x PWM fan ports (4-pin)
DDR4 memory up to 2.666 MHz
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.

Special refinements of the MSI A320M Grenade are also the stabilizing "Steel Armor" and the Click BIOS 5 for easy fine tuning of the system. Finally, three fans with a 4-pin PWM connector can be connected directly to the board. On the mainboard, additional devices and components can be connected to the MSI A320M Grenade via USB 3.0 and 2.0, Gigabit LAN, universal PS / 2 or three audio jacks for 7.1 sound. In addition, three monitor outputs (HDMI, VGA and DVI-D) are available for the display via an integrated APU graphics unit (optional).
