Memory
3 items
- DIMM slots
- 4
Physical DDR5 DIMM positions; not a capacity or speed guarantee.
Source - Maximum listed memory
- 256 GB
Manufacturer capacity ceiling; CPU, BIOS and module validation apply.
Source - Memory type, slots and limit
- 4 DDR5 DIMM slots; dual channel; up to 256 GB; up to DDR5-9200+ (OC); Intel XMP; non-ECC unbuffered; CUDIMM support
MSI specifies Intel XMP 3.0. The overclocked speed is MSI's 1DPC 1R maximum; MSI lists 1DPC 2R up to 7200+, 2DPC 1R up to 6400+ and 2DPC 2R up to 5600+ MT/s. · CPU, BIOS and validated DIMM population determine supported capacity and speeds; MSI states compatibility and speeds vary with CPU and memory configuration. DDR4 and DDR5 are not interchangeable.

Expansion slots
3 items
- Expansion slots and electrical links
- 1 × PCIe 5.0 x16; 1 × PCIe 4.0 x4; 1 × PCIe 4.0 x1
PCI_E1 (x16) connects to the CPU; PCI_E2 (x1) and PCI_E3 (x4) connect to the chipset. · PCI_E3 runs at x2 when a PCIe device is installed in PCI_E2. MSI's pages describe the slot lengths differently (two x16-length slots and one x1 slot on the specification page, three x16-length slots in the datasheet); check product photos before relying on a full-length second slot.
- Lane-sharing restrictions
- PCI_E3 runs at x2 when a PCIe device is installed in PCI_E2.
Exact manufacturer restrictions; inspect the complete manual when planning simultaneous devices.
Source - PCIe release button
- Yes
MSI EZ PCIe Release operates the graphics-card slot latch. This is an installation control, not a PCIe bandwidth or gaming-performance measurement.

Storage
6 items
- M.2 storage slots
- 3
Storage M.2 positions only (the Key-E Wi-Fi slot is separate). Installing a 22110 SSD in M2_2 limits M2_3 to 2242/2260 SSDs.
- SATA ports
- 4
SATA 6 Gb/s connectors, not supplied drives or power cables. MSI lists no SATA lane-sharing restriction on the specification page.
- Storage interfaces
- 1 × M.2 PCIe 5.0 x4; 2 × M.2 PCIe 4.0 x4; 4 × SATA 6 Gb/s
M.2_1 connects to the CPU; M.2_2 and M.2_3 connect to the chipset. · M.2_1 accepts 2280/2260, M.2_2 22110/2280/2260 and M.2_3 2280/2260/2242 drives. Installing a 22110 SSD in M2_2 limits M2_3 to 2242/2260 SSDs. MSI refers to the manual for M.2 heatsink restrictions.
- SATA RAID modes
- RAID 0/1/5/10
MSI lists these modes for SATA storage devices; check the manual and BIOS configuration before building an array.
Source - NVMe RAID modes
- Not listed by the manufacturer
MSI lists RAID modes for SATA drives only; NVMe RAID support is not stated. · Check the manual or BIOS documentation before relying on NVMe arrays.
Source - Tool-less M.2 heatsink handling
- Yes
MSI describes tool-less SSD and Shield Frozr installation/removal under EZ M.2 Shield Frozr II. This does not establish measured cooling effectiveness or compatibility with every SSD heatsink.

USB & rear connections
2 items
- Thunderbolt ports
- 1 × Thunderbolt 4 USB-C; up to 40 Gb/s; up to 15 W charging
Thunderbolt devices and suitable cables required; USB4/USB 3 modes can have different limits.
Source - Motherboard display outputs
- HDMI 2.1 FRL (up to 8K 60 Hz); DisplayPort 1.4 (up to 4K 60 Hz); Thunderbolt 4 USB-C with DisplayPort 2.1 UHBR20 (up to 4K 120 Hz / 8K 60 Hz)
Requires processor integrated graphics; MSI states graphics specifications vary with the installed CPU. Discrete GPU outputs are separate.
Networking
1 item
- Network interfaces
- Intel Killer E5000 5 Gb Ethernet; Intel Killer BE1750x Wi-Fi 7; Bluetooth 5.4
MSI's datasheet names the Ethernet controller Killer E5000B; the specification page calls it Killer E5000. Both give 5 Gb/s. · MSI states Wi-Fi 7 will be ready in Windows 11 SV3 and Bluetooth 5.4 depends on Microsoft's Windows 11 plan; 6 GHz band support depends on country regulations. Compatible router and drivers required.
