Socket & CPU Support

The board uses the LGA 1700 socket and runs 12th and 13th Gen Intel Core, Pentium Gold and Celeron processors. A dedicated LGA 1700 mounting bracket is required for cooler installation. A BIOS update may be needed before a 13th Gen CPU will post.

Memory Configuration

Four 288-pin slots accept DDR5 memory up to 128 GB in dual-channel mode. JEDEC speed is 4800 MT/s; overclocked limits reach 6200+ with one single-rank DIMM, 5200+ with one dual-rank DIMM and 4000+ when all four slots are populated.

Expansion & Connectivity

One PCIe 4.0 x16 slot, one PCIe 3.0 x16 slot wired at x4 and one PCIe 3.0 x1 slot provide add-in card options. Two M.2 Key M sockets support 2242, 2260 and 2280 drives; the CPU-linked slot runs PCIe 4.0 x4 while the chipset slot adds SATA 6Gb/s capability. Four SATA ports, 2.5 GbE LAN, WIFI 6 and 7.1-channel Realtek ALC897 audio complete the I/O.

Questions about this item

What does 6200+ DDR5 overclocking mean once the board is in a real machine?

With one single-rank DIMM per channel the board can run memory up to 6200+ MT/s, but adding a second module per channel drops the ceiling to 4000 MT/s so the top speed depends on how many sticks you install.

What does the 2.5G LAN and WIFI 6 interface cap in practice?

The wired port tops out at 2.5 Gb/s and the wireless radio reaches 2400 Mb/s under MU-MIMO and BSS color operation, so real-world throughput will be limited by those ceilings.

What does the board physically need to fit or mount a CPU cooler?

A dedicated LGA 1700 mounting bracket is required for the socket, and the Micro ATX form factor fits standard standoff layouts in compatible cases.
