ASUS Prime X370-A, AMD X370 motherboard socket AM4 [90MB0UN0-M0EAY0]

Motherboards with the AM4 processor base serve as a platform for the AMD Ryzen Summit Ridge quad-core, Hexacore and Octacore CPUs, as well as Bristol Ridge and Raven Ridge A-Series Deskop APUs with integrated graphics or the latter Derived Athlon X4 without iGPU. The AMD X370, B350 and A320 chipsets for the enthusiast, mainstream and base segment provide many advanced I / O interfaces and connections for peripherals, while additional data lines are directly controlled by the CPU or APU.

AMD Logo AM4 motherboards also support fast and energy-efficient DDR4 memory in dual channel mode, depending on the board, even with ECC error correction support. The highly developed "Zen" microarchitecture, together with its AM4 platform, forms the ideal basis for powerful systems in any application.
Features of the ASUS Prime X370-A in ATX format

The ASUS Prime X370-A is a motherboard in ATX format and has graphics cards with a fast PCI Express 3.0 slot that is connected with full 16 lanes. There is also a PCIe 2.0 slot with x4 connection as well as two PCIe 2.0 x1 slots and two PCI slots for other expansion cards. Up to 64 GB of DDR4 memory 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 headers for USB 2.0 for two and four ports, respectively.

Such as SSDs and hard disks, the board is managed by six 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 110 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.

A small highlight on the ASUS Prime X370-A is that there is a USB-3.1 connector with a type A connector at the I / O panel on the back of the motherboard. USB 3.1 or USB 3.1 Gen 2 achieves maximum speeds of 10 Gbit / s per port. A special feature is the integrated ASUS "Aura" RGB LED lighting, which allows for individualized lighting effects in all colors of the rainbow and can be easily controlled.

Finally, three fans with a 4-pin PWM connector can be connected directly to the board. On the mainboard back, additional devices and components can be connected to the ASUS Prime X370-A via USB 3.1, 3.0 and 2.0, Gigabit LAN, universal PS / 2 or three audio jacks for 7.1 sound via the I / O shield connect. In addition, three monitor outputs (HDMI, DVI-D and D-Sub) are available for display via an integrated APU graphics unit (optional).
