Z490 ATX Motherboard for 10th Gen Intel

The GIGABYTE Z490 GAMING X AX is an ATX board built for 10th generation Intel Core i9, i7, i5, i3, Pentium and Celeron processors in the LGA1200 package. It uses the Intel Z490 chipset and provides four DDR4 slots for dual channel memory up to 128GB. Integrated Intel HD Graphics are served by one HDMI 1.4 port with HDCP 2.3 support at 4096x2160 resolution and 30 Hz refresh.

PCIe 3.0 Lanes and M.2 Constraints

The primary PCI Express 3.0 x16 slot runs at x16 and a second x16 sized slot runs at x4, while three x1 slots complete the layout. Two M.2 sockets accept 2242, 2260, 2280 and 22110 form factors with both SATA and PCIe x4 or x2 signalling. Six SATA 6Gb/s ports support RAID 0, 1, 5 and 10 and the platform is Intel Optane Ready for caching acceleration.

Pre Mounted I/O Shield and Q Flash Plus

A pre installed I/O shield removes the risk of forgotten installation and the Q Flash Plus button updates the BIOS without a CPU, memory or graphics card fitted. Rear USB includes one 3.2 Gen2 Type A, five 3.2 Gen1 and two 2.0 ports, while front headers add two 3.2 Gen1 and two 2.0 connections. Networking uses Intel GbE LAN at 1Gbps plus WiFi 6 and Bluetooth 5.

Questions about this item

Should I pick the version with one M.2 slot or the version with two M.2 slots?

This model has two M.2 connectors: one supports type 2242/2260/2280/22110 SATA and PCIe x4/x2 SSDs, the other supports type 2242/2260/2280 SATA and PCIe x4/x2 SSDs.

What does the DDR4 4600(O.C.) figure mean once the board is in a real machine?

With a 10th Gen Core i9 or i7 installed, the memory controller can run DDR4 modules up to 4600 MHz when overclocked; lower-tier CPUs top out at 2666 MHz without overclocking.

Which Wi-Fi standard is onboard and what speed does it cap at in practice?

The board includes Intel WiFi 6 and Bluetooth 5; WiFi 6 can reach multi-gigabit throughput in typical conditions, while the wired Intel GbE LAN is limited to 1 Gbps.
