1. CPU socket The motherboard comes with a AMD Socket AM4 designed for AMD Ryzen™ 5000 Series / 5000 G-Series / 4000 G-Series / 3000 Series / 3000 G-Series / 2000 Series / 2000 G-Series Desktop Processors. Chapter 1 1-4 • 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. DO NOT force the CPU into the socket to prevent bending the connectors on the socket and damaging the CPU.
2. DIMM slots The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for DDR4 (Double Data Rate 4) memory modules. Chapter 1 A DDR4 memory module is notched differently from a DDR, DDR2, or DDR3 module. DO NOT install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.
Memory configurations You may install 4 GB, 8 GB, 16GB, and 32 GB unbuffered and non‑ECC DDR4 DIMMs into the DIMM sockets. Chapter 1 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. Any excess memory from the higher-sized channel is then mapped for single-channel operation.
3. Expansion slots Chapter 1 Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. Please refer to the following table for the recommended VGA configuration.
