Source - Memory type, slots and limit
- 4 DDR5 DIMM slots; dual channel; up to 256 GB; up to DDR5-7200+ (OC); Intel XMP; non-ECC unbuffered
MSI specifies Intel XMP 3.0. The overclocked speed is MSI's 1DPC 1R maximum; MSI lists 1DPC 2R up to 6600+, 2DPC 1R up to 6400+ and 2DPC 2R up to 5600+ MHz. · CPU, BIOS and validated DIMM population determine supported capacity and speeds. DDR4 and DDR5 are not interchangeable.
Expansion slots
2 items
- Expansion slots and electrical links
- 1 × PCIe 5.0 x16; 1 × PCIe 4.0 x4; 2 × PCIe 3.0 x1
PCI_E1 connects to the CPU; PCI_E2 to PCI_E4 connect to the chipset. MSI lists three x16-length slots and one x1 slot. · Electrical link widths, not a guarantee of installed-system performance. CPU and slot population restrictions apply.
Source - Primary expansion-slot link
- PCI_E1: CPU PCIe 5.0 up to x16
The stated PCI_E1 electrical link is separate from M.2 storage links. It does not establish the lane allocation of every expansion slot or measured GPU performance.

- 1 × USB 20 Gb/s (1 Type-C); 4 × USB 10 Gb/s (3 Type-A + 1 Type-C); 4 × USB 5 Gb/s (4 Type-A); 6 × USB 2.0
Manufacturer combined port/header totals; these are not all rear-panel sockets. Use the connection diagram and manual to locate them.
Source - Processor-dependent display outputs
- HDMI 2.1: up to 4K 60 Hz; DisplayPort 1.4: up to 8K 60 Hz
MSI's datasheet gives 4K 60 Hz for HDMI 2.1 and DisplayPort 1.4; the per-port maximums come from MSI's current specification page. · These outputs require a processor with integrated graphics. The manufacturer says graphics specifications vary with the installed CPU; this is not an independent display or GPU performance test.
Source - Rear USB ports
- 2 USB 2.0; 2 USB 5 Gb/s Type-A; 3 USB 10 Gb/s Type-A; 1 USB 20 Gb/s Type-C
Rear port inventory only. Rated interface rates are not simultaneous measured throughput; USB-C connector shape does not establish USB4 or charging power.
Source - Front USB header capacity
- 4 USB 2.0; 2 USB 5 Gb/s Type-A; 1 USB 10 Gb/s Type-C
Manufacturer-listed front connectivity requires compatible case ports and cabling. These are not additional rear-panel sockets.

Diagnostic indicators are not a numeric POST display or proof that a fault will be automatically repaired.
Source - Rear Flash BIOS button
- Yes
The rear-panel inventory explicitly lists a Flash BIOS Button. CPU-free recovery procedure and USB preparation require the board manual.
