Utilizing the AMD A520 chipset, this motherboard is designed for use with CPUs that support the AM4 socket. Install up to 128GB of dual-channel DDR4 RAM across four slots, with speeds up to 4733 MHz supported when overclocking. Storage drives can be installed using four SATA III connectors or an M.2 slot. A graphics card can be installed using the PCIe 3.0 x16 slot, while two PCIe 3.0 x1 slots offer room for further expansion. A rear I/O panel sports four USB 3.2 Gen 1 and two USB 2.0 ports, as well as a PS/2 combo port for connecting legacy mice or keyboards. DisplayPort, HDMI, and DVI-D outputs accommodate displays, while an RJ45 port supports Gigabit Ethernet. Three 3.5mm audio ports are also present on the rear panel. The Gigabyte A520M DS3H AM4 Micro-ATX Motherboard utilizes the Realtek ALC887 audio codec and supports Windows 10 64-bit operating systems. High Speed Gigabit LAN with Automatic Bandwidth Allocation Realtek 8118 LAN is a high performance and friendly network chip for gaming players with automatic bandwidth allocation to ensure the highest network priority of the game or application. It can provide users the most comprehensive features and the fastest and smoothest Internet experience. HDMI 2.1 for 4K / 60P / 21:9 / HDCP 2.3 Support HDMI 2.1, which is backwards compatible with HDMI 2.0/ 1.4 and offering 48 Gb/s of bandwidth – twice times more than previous generation. This unlocks the potential for users to transfer multiple video streams, as well as a native cinematic 21:9 ratio (which most movies are shot in), Full HDR and HDCP 2.3 support, to offer the best visual experience for viewers. RGB FUSION 2.0 With A520 Motherboards, RGB Fusion 2.0 is even better with Addressable LEDs. RGB Fusion 2.0 offers users the option to control onboard RGB and external RGB / Addressable LED light strips* for their PC build. Already feature filled with colors and patterns, RGB Fusion 2.0 are now upgraded to improve the Addressable LED support. With external Addressable LED strips, where each LED is digitally addressable that users can experience even more patterns, styles, and illuminations. With A520 Motherboards support the external 5V Addressable LED lighting strips and up to 300 LED lights. RGB Fusion 2.0 with Addressable LEDs comes with new patterns and various speed settings with more to come.

Uncompress the downloaded BIOS file, save it to your USB flash drive, and rename it to GIGABYTE.bin. Note: The USB flash drive must use the FAT32/16 file system. Insert the USB flash drive into the white USB port or BIOS Q Flash port on the back panel of your motherboard (USB port may not be labelled on all models, checking the user manual is recommended) Connect the power cables to the CPU 8 Pin power connector (connect either one if there are two) and mainboard 24 Pin power connector. Press the Q-Flash Plus button (location may vary by model) and the system will automatically search and match the BIOS file in the USB flash drive on the white USB port. The QFLED and the Q-Flash Plus button on the rear panel will flash during the BIOS matching and flashing process. Wait for 2-3 minutes and the QFLED will stop flashing when the BIOS flashing is complete. ..
