LGA 1200 Motherboard for 10th Gen Intel

The ASUS ROG STRIX Z490-A GAMING fits the Intel LGA 1200 socket and supports 10th Gen Intel Core, Pentium Gold and Celeron processors. It is built for users who need a full-size ATX board with robust 12+2 Dr. MOS power stages and ProCool II connectors. Dual-channel DDR4 memory scales up to 128 GB across four 288-pin slots.

PCIe 3.0 and Storage Interfaces

The CPU provides three PCIe 3.0 x16 slots that operate at x16 or x8+x4+x4, while the Z490 chipset adds one PCIe 3.0 x4 slot running at up to x2 mode and one PCIe 3.0 x1 slot. Six SATA 6Gb/s ports support RAID 0, 1, 5 and 10, and Intel Optane memory is ready. Two M.2 sockets accept 2242, 2260, 2280 and 22110 modules, with the first supporting both SATA and PCIe 3.0 x4 and the second PCIe 3.0 x4 only.

DDR4 4600 Overclock Ceiling

The memory controller validates speeds from 2133 MHz up to 4600 MHz when overclocked, covering every step listed in the specification. This ceiling decides whether the board matches a high-frequency DDR4 kit or a standard JEDEC set.

Questions about this item

Which DDR4 speed should I pick for the ROG STRIX Z490-A GAMING?

The board supports DDR4 up to 4600 MHz when overclocked and runs natively at 2666 MHz; choose a kit rated for your target speed and enable the XMP profile in BIOS to reach it.

What does the 12+2 power stage design deliver in a real build?

Twelve Dr. MOS stages for the CPU core and two for the system agent give stable, efficient current delivery so 10th Gen Intel Core processors can sustain high boost clocks under load.

How fast is the onboard 2.5 Gb Ethernet in practice?

The Intel 2.5Gb Ethernet controller provides up to 2.5 gigabits per second throughput, roughly two and a half times standard gigabit LAN, limited by your router, cabling and internet plan.
