1.2.1 Layout contents 1. CPU socket The motherboard comes with an AMD Socket AM5 designed for AMD Ryzen™ 7000 Series Desktop Processors. For more details, refer to Central Processing Unit (CPU). 2. DDR5 DIMM slots The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for DDR5 (Double Data Rate 5) memory modules. For more details, refer to System memory. 3. Expansion slots This motherboard supports two PCIe x16 graphics cards and two PCIe 4.
• If you want to use two high-end PCI Express x16 cards, use a PSU with 1000W power or above to ensure the system stability. 6. M.2 Slots (Key M) The M.2 slots allow you to install M.2 devices such as M.2 SSD modules. For AMD Ryzen™ 7000 Series Desktop Processors: M.2_1 slot (Key M), type 2242/2260/2280/22110 (supports PCIe 5.0 x4 mode) M.2_2 slot (Key M), type 2242/2260/2280/22110 (supports PCIe 4.0 x4 mode) 7.
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.
14. COM Port header COM RXD DTR DSR CTS This header is for a serial (COM) port. Connect the serial port module cable to this header, then install the module to a slot opening at the back of the system chassis. 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].
The 2-pin header allows you to connect the system power button.
