1 Product introduction 1.1 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings. Unplug the power cord from the wall socket before touching any component. • Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity.
1.2.1 Layout contents 1. CPU socket The motherboard comes with an AMD Socket AM4 designed for 3rd Gen AMD Ryzen™ and 3rd Gen AMD Ryzen™ with Radeon™ Graphics Processors. For more details, refer to Central Processing Unit (CPU). 2. DDR4 DIMM slots The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for DDR4 (Double Data Rate 4) memory modules. For more details, refer to System memory. 3. Expansion slots This motherboard supports two PCIe x16 graphics cards and one PCIe 3.
• For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12V Specification 2.0 (or later version) and provides a minimum power of 350 W. • We recommend that you use a PSU with a higher power output when configuring a system with more power-consuming devices. The system may become unstable or may not boot up if the power is inadequate.
Before you install or remove any component, ensure that the power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, or components. • Actual lighting and color will vary with LED strip. • If your LED strip does not light up, check if the addressable RGB LED strip is connected in the correct orientation, and the 5V connector is aligned with the 5V header on the motherboard.
We recommend that you connect a high-definition front panel audio module to this header to avail of the motherboard’s highdefinition audio capability. • If you want to connect a high-definition front panel audio module to this header, set the Front Panel Type item in the BIOS setup to [HD Audio]. By default, this header is set to [HD Audio].
18. Q-LEDs The Q-LEDs check key components (CPU, DRAM, VGA, and booting devices) during the motherboard booting process. If an error is found, the critical component’s LED stays lit up until the problem is solved. The Q-LEDs provide the most probable cause of an error code as a starting point for troubleshooting. The actual cause may vary from case to case. 19. BIOS FlashBackTM LED The FlashBack™ LED lights up or blinks to indicate the status of the BIOS FlashBack™.
5. 2.5G Ethernet port. This port allows 2.5Gbps Ethernet connection to a Local Area Network (LAN) through a network hub. Refer to the table below for the Ethernet port LED indications. Realtek RTL8125B 2.5G Ethernet port LED indications ACT/LINK LED Activity Link LED Speed LED Status Description Status Description OFF No link OFF No link GREEN Linked GREEN 2.5 Gbps connection BLINKING Data activity ORANGE 1 Gbps / 100 Mbps / 10 Mbps connection SPEED LED LAN port 6. USB 3.
1.3 Central Processing Unit (CPU) This motherboard comes with an AMD Socket AM4 designed for 3rd Gen AMD Ryzen™ and 3rd Gen AMD Ryzen™ with Radeon™ Graphics Processors. Unplug all power cables before installing the CPU. The AM4 socket has a different pinout design. Ensure that you use a CPU designed for the AM4 socket. The CPU fits in only one correct orientation.
1.4 System memory This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module (DIMM) sockets. The figure illustrates the location of the DDR4 DIMM sockets: • • • DIMM_A1 DIMM_A2* Channel Channel A DIMM_A1 & DIMM_A2* Sockets DIMM_B1 DIMM_B2* Channel B DIMM_B1 & DIMM_B2* You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration.
Installing a DIMM 1 2 A A B To remove a DIMM A B 1.5 M.2 installation 1 2 OPTIONAL 1-10 • Ensure to install the bundled M.2 rubber pad before installing your single sided M.2 storage device. • DO NOT install the bundled M.2 rubber pads when installing a double-sided M.2 storage device. The rubber pad installed by default is compatible with double sided M.2 storage devices. • The diagrams in this section are for reference only. • The M.2 is purchased separately.
