Description

Essential Computing for Office/Home with Media Playback

The BIOSTAR A320MH features the AMD A320 chipset for use with AM4 processors in a micro-ATX form factor. It offers essential features and performance to meet needs for daily computing with its dual DIMM slots supporting up to 32GB of 2667MHz DDR4 memory, one PCI-E 3.0 x16 slot and two PCI-E 1.0 x16 slots. The A320MH packs a Realtek RTL8111G controller for up to 100MB/s Ethernet connectivity along with two USB 3.1 Gen1 ports, one USB 3.1 Gen1 header, four USB 2.0 Ports and two USB 2.0 headers for lots of expansion possibilities.

FEATURES

  • AMD A320 single chip architecture
  • Supports AMD Ryzen CPU / APU
  • Supports 2-DIMM DDR4–2933/2667/240­0/2133/1866 up to 32G maximum capacity
  • Supports USB 3.2 Gen1
  • Supports HDMI

AMD A320 CHIPSET
AMD's A320 chipset provides a simple, stable platform and more than enough connectivity and bandwidth ​options to satisfy both demanding home users and media aficionados.

DX12
DirectX 12 introduces the next version of Direct3D, the graphics API at the heart of DirectX. Direct3D is one of the most critical pieces of a game or game engine, and we've redesigned it to be faster and more efficient than ever before. Direct3D 12 enables richer scenes, more objects, and full utilization of modern GPU hardware.

HDMI 4K2K
The new 4K2K resolution enables high-definition image display with four times the resolution of full HD. 4K2K display is faithfully expressed with bright, highly detailed content that fills the entire screen with lifelike images. Connects with PCs via a single HDMI cable to display 4K2K data.

USB 3.2 Gen1 Type-A
USB 3.2 Gen1 delivers a compelling performance boost and can be used to connect multiple devices without worrying about compatibility. It is capable of data transfer speeds up to 5Gbps and backwards compatible with all existing USB products.

MOISTURE-PROOF PCB
The popularity of PC usage in a working environment is increasing and as well as the risk of deteriorating and moisture (rural, coastal, etc.). The PCB can oxidizing easily due to damp or absorbed moisture, and ionic migration of Conductive Anodic Filament (CAF) is generated. The PCB meets the high density and high reliability requirements for moisture-proof.

ESD PROTECTION
ESD (Electrostatic Discharge) is the major factor that destroys PC by electrical overstress(EOS). ESD happens when users touch any devices that connect to the PC, which may result in damage to motherboard or components. ESD protection is designed to protect the motherboard and equipment from damage by EOS.

OC / OV / OH PROTECTION
All BIOSTAR special circuit design detects overvoltage conditions and prevents voltage surges from spreading in real time. It also actively cuts off the overvoltage supply to protect your system. Over current protection helps avoid motherboard damage when overclocking or when unusual current occurs. Over heat protection prevents the motherboard & CPU from burning when exceeding the temperature limitation.
