In terms of memory, it has four DDR4 memory slots that can support up to 128GB of RAM. It supports various DDR4 memory speeds, including 1866, 2133, 2400, 2667, 2800, 2933, 3000, 3066, and 3200 MHz by JEDEC. Additionally, it supports higher speeds through A-XMP OC MODE, such as 3466, 3600, 3733, 3866, 4000, 4133, 4266, and 4400+ MHz. The maximum memory speeds depend on the configuration of the memory modules.
For expansion slots, it has one PCIe 4.0/3.0 x16 slot (PCI_E1), one PCIe 3.0 x16 slot (PCI_E3) running at x4 speed, and two PCIe 3.0 x1 slots. However, if you install a PCIe SSD in the M.2_2 slot, the PCI_E3 slot will become unavailable.
The motherboard supports onboard graphics with an HDMI 2.1 port and a DisplayPort, allowing for a maximum resolution of 4096×2160 at 60Hz. The maximum shared memory for graphics is 16GB, but it may vary depending on the installed CPU.
Multi-GPU support is available for 2-Way AMD CrossFire technology, allowing for multiple graphics cards to be used simultaneously.
In terms of storage, the AMD B550 chipset provides six SATA 6Gb/s ports and two M.2 slots (Key M). The M2_1 slot, connected to the AMD processor, supports PCIe 4.0/3.0 x4 and SATA 6Gb/s, while the M2_2 slot, connected to the AMD B550 chipset, supports PCIe 3.0 x4. Both slots can accommodate storage devices in the sizes of 2242, 2260, 2280, and 22110, depending on the installed processor.
RAID functionality is supported for SATA storage devices (RAID 0, RAID 1, and RAID 10) and M.2 NVMe storage devices (RAID 0 and RAID 1).
The motherboard provides various USB ports, including USB 3.2 Gen 1 5Gbps ports, USB 2.0 ports, and USB 3.2 Gen 2 10Gbps ports (Type-C and Type-A).
For audio, it features the Realtek ALC892/ALC897 codec, providing 7.1-channel high-definition audio with S/PDIF output.
Networking is supported through the Realtek 8111H Gigabit LAN controller.
The motherboard has several internal connectors for power, storage, USB, fans, audio, and LEDs. It also includes a variety of back panel ports such as PS/2 combo port, DisplayPort, LAN port, USB ports, HDMI, and audio connectors.
Additional features include an EZ LED Control switch, EZ Debug LEDs, and an I/O controller chip (NUVOTON NCT6687-R) for enhanced functionality. The motherboard also has hardware monitoring capabilities for temperature and fan speed detection and control.
The MSI MPG B550 Gaming Plus is an ATX form factor motherboard.
