Ready for 12th and 13th Gen Intel Core
This microATX board fits the LGA 1700 socket and accepts 12th and 13th Gen Intel Core, Pentium Gold and Celeron processors. A BIOS update may be needed before a 13th Gen CPU will boot. It targets builders who want a compact platform with wired and wireless networking.
Memory standard DDR4 up to 5333 OC
Four 288-pin slots run dual-channel DDR4 at speeds from 2133 to 5333 when overclocked. The maximum supported capacity is 128 GB. ASUS OptiMem II trace routing helps preserve signal integrity at higher frequencies.
Two M.2 slots and one PCIe 4.0 x16
The primary M.2 slot connects through the CPU and supports 2242, 2260 and 2280 drives at PCIe 4.0 x4 with 12th Gen processors. A second chipset-linked M.2 slot also runs PCIe 4.0 x4. The single PCIe 4.0 x16 slot handles one graphics card; three additional slots operate at PCIe 3.0 x4 or x1.

Questions sur cet article
How does the DDR4 5333 OC memory speed translate to actual system performance on this board?
The 5333 MT/s figure is an overclocked ceiling that requires compatible DDR4 modules and manual tuning in the BIOS; real-world stability depends on the memory kit quality and CPU memory controller.
What does the PCIe 4.0 x16 slot cap at when paired with a 12th or 13th Gen Intel Core processor?
With a supported 12th or 13th Gen CPU the primary x16 slot runs at PCIe 4.0 x16, while the three secondary x16 slots operate at PCIe 3.0 x4 or x1 depending on configuration.
What physical space and mounting hardware does the LGA 1700 socket need in a microATX chassis?
The board uses the microATX form factor and requires a dedicated LGA 1700 mounting bracket; ensure the case supports microATX and provides the correct backplate clearance.
