• Four DDR4 DIMM slots supporting up to 128 GB of memory at speeds up to 4400 MHz (OC).
• Dual-channel architecture for optimal bandwidth and low latency.

PCIe & Expansion

The board features five PCIe slots, including:

• One PCIe 4.0 x16 slot (x8 mode when paired with a second GPU) for high‑end graphics cards.
• Two PCIe 3.0 x1 slots for additional expansion cards such as sound or capture devices.
• One M.2 slot (PCIe 4.0) and one M.2 slot (PCIe 3.0) for ultra‑fast NVMe SSDs.

Storage & Connectivity

The PRIME B550‑PLUS offers a comprehensive storage solution:

• Six SATA 6 Gb/s ports for traditional HDDs and SATA SSDs.
• Dual M.2 slots, one supporting PCIe 4.0 for maximum throughput, the other PCIe 3.0.
• Integrated Realtek RTL8111H Gigabit LAN for reliable wired networking.
• Optional Wi‑Fi 5 (802.11ac) and Bluetooth can be added via a compatible module.

USB & I/O Ports

The motherboard boasts an extensive array of USB connections:

• Four USB 3.2 Gen 1 Type‑A ports.
• Two USB 3.2 Gen 2 (Type‑A) for high‑speed data transfer.
• One USB 3.2 Gen 2 Type‑C port, enabling fast charging and versatile connectivity.
• Additional USB 2.0 ports for legacy devices.
