Rev. 3.0 of the Series 8 GA-B85M-DS3H Motherboard from Gigabyte is designed to fit in cases that support the Micro ATX form factor. It supports Intel Core i7, i5, i3, Pentium, and Celeron processors in the Intel LGA 1150 socket, as well as the Intel B85 Express chipset. This motherboard is compatible with Windows 8.1, 8, and 7 operating systems.

The Micro ATX form factor of the GA-B85M-DS3H has four RAM slots that can support up to 32GB of 1333 and 1600 MHz non-ECC DDR3 RAM, or 8GB per slot. The GA-B85M-DS3H also has a total of 4 x SATA III 6 Gb/s connectors, 2 x SATA II 3 Gb/s connectors, 4 x USB 3.0/2.0 ports and 8 x USB 2.0/1.1 ports. For PCIe expansion, there is one PCIe 3.0 x16 slot and two PCIe 2.0 x1 slots. Graphically, the GA-B85M-DS3H has integrated Intel HD graphics with HDMI, DVI-D, and VGA outputs. The HDMI output supports a maximum resolution of 4096 x 2160 @ 24 Hz, while the DVI-D and VGA outputs both support a maximum resolution of 1920 x 1200. Up to 1GB of shared graphics memory is available to the integrated controller.

Network connectivity is achieved using a single Gigabit Ethernet port and the integrated Realtek ALC887 codec supports HD audio with 2, 4, 5.1, and 7.1 channel surround. In the case that the BIOS fails, UEFI DualBIOS provides your motherboard with a 'Main BIOS' and a 'Backup BIOS' that helps protect users in the case of a virus attack, hardware malfunction, improper OC settings, or power failure during an update. Other built-in features include ESD protection, on/off charge technology, LAN optimisation, the Gigabyte App Centre, system tuning, fan controls, BIOS updates from within Windows, Gigabyte EZ Setup, and more. Included with this motherboard are two SATA cables.

Key Features

Gigabyte Ultra Durable 4 Plus

  • Gigabyte Ultra Durable 4 Plus debuts on Gigabyte 8 Series motherboards, with a range of features and component choices that help provide increased performance, cool and efficient operation, and extended motherboard lifespan


  • Gigabyte uses All Solid Caps (Capacitors) and Low RDS(on) MOSFETs which are rated to work at higher temperatures to help provide a longer lifespan

Gigabyte UEFI DualBIOS

  • Gigabyte motherboards feature Gigabyte DualBIOS, a technology from Gigabyte that protects one of your PC's BIOS. Gigabyte DualBIOS means that your motherboard has both a 'Main BIOS' and a 'Backup BIOS', helping protect users from a BIOS failure due to a virus attack, hardware malfunction, improper OC settings, or power failure during the update process

Audio Capacitors

  • Gigabyte Ultra Durable motherboards use Nippon Chemicon ARE series audio capacitors. These professional audio capacitors help deliver high quality sound resolution and sound expansion to create the realistic sound effects

Dedicated Audio Hardware Zone

  • - Separation on the PCB layer helps protect the board's analogue audio components - Separate analogue and digital ground helps to protect against Electromagnetic Interference (EMI)

ESD Protection for USB and LAN (USB 3.0 only)

  • Gigabyte 8 Series motherboards help provide electrostatic discharge (ESD) protection for both your Ethernet LAN and USB ports, both common sources of ESD-related failures. Each LAN and USB port is paired with a dedicated protection filter that can withstand electrostatic discharges, helping to protect your system from common electrical surges and even direct lighting strikes


  • HDMI is a High-Definition Multimedia Interface which provides up to 5 Gb/s of video transmitting bandwidth and 8-channel high quality audio all through a single cable. Able to transmit uncompressed digital video and audio, HDMI helps ensures crisp rendering of digital content up to 1080p without the quality losses associated with analogue interfaces and their digital-to-analogue conversion. In addition, HDMI is compatible with HDCP (High-bandwidth Digital Content Protection), allowing the playback of Blu-ray/HD DVD and other protected media content


  • DVI (Digital Visual Interface) is a video interface standard designed for carrying uncompressed digital video data and also to maximise the visual quality of digital display devices, such as LCD monitors, digital projectors, and more. In addition, the DVI interface is compatible with HDCP (High-bandwidth Digital Content Protection)

On/Off Charge Technology

  • Gigabyte On/Off Charge technology allows you to charge your iPhone, iPad, and iPod Touch regardless of whether your PC is on, in standby mode or even off. A derivative of Gigabyte's 3x USB Power feature, On/Off Charge enables devices to draw more current from a Gigabyte motherboard's USB ports than standard USB ports allow

LAN Optimiser

  • The Gigabyte LAN Optimiser is designed to allow the user to manage different types of network traffic so that data streams such as HD media, web browsing, or online gaming can be prioritised, taking precedence over large data downloads that tend to strangle overall network bandwidth

Gigabyte App Centre

  • The Gigabyte App Centre gives you access to wealth of Gigabyte apps that help you get the most from your Gigabyte motherboard. Using a simple and unified user interface, the Gigabyte App Centre allows you to launch all Gigabyte apps installed on your system

Gigabyte EasyTune

  • GIGABYTE EasyTune provides a simple and easy-to-use interface that allows users to fine-tune their system settings

Gigabyte Smart Fan 2

  • As well as offering an increased amount of system fans, GIGABYTE 8 Series motherboards feature updated and improved CPU and system fan speed controls with individual airflow and speed settings available via a dedicated digital controller. Gigabyte Smart Fan 2 allows you to configure CPU fans and system fans

Gigabyte @BIOS

  • The Gigabyte @BIOS app allows you to update your system's BIOS from within Windows using a graphical user interface by automatically downloading the latest version from the Gigabyte servers

Gigabyte EZ Setup

  • Gigabyte EZ Setup combines several key utilities designed to simplify instal and configuration procedures for several Gigabyte apps including Disk Mode Switch, Smart Connect, EZ Rapid Start, and EZ Smart response
