LGA 1200 ATX motherboard

The GIGABYTE Z490 UD AC is an ATX motherboard built around the Intel Z490 chipset and the LGA 1200 socket. It supports 10th Generation Intel Core i9, i7, i5, i3, Pentium and Celeron processors. The board provides four 288-pin DDR4 slots with a maximum capacity of 128 GB in dual-channel mode.

Builders needing Wi-Fi and dual M.2

This board suits builders who want integrated Intel Wi-Fi 802.11ac and Bluetooth 5 plus two M.2 connectors for SATA or PCIe SSDs. It also offers six SATA 6Gb/s ports, Realtek GbE LAN, Realtek ALC887 audio with 7.1-channel output, and rear USB 3.2 Gen 2 Type-A and Type-C ports. Users requiring more than two M.2 slots or a LAN speed above 1 Gbps should consider other options.

11+1 phase digital VRM with DrMOS

The power delivery uses a direct 11+1 phase digital design with DrMOS stages and an extended MOS heatsink. This VRM arrangement is the specification that determines whether the board can sustain the current demanded by high-end 10th Generation Core i9 processors during extended loads.

Questions about this item

Which 10th Gen Intel Core processor socket does the Z490 UD AC require?

The board uses the LGA 1200 socket, so you need a 10th Gen Intel Core i9, i7, i5, i3, Pentium or Celeron processor in that package.

Can I keep my existing DDR4 memory kits when moving to this motherboard?

Yes, the four 288-pin slots accept dual-channel DDR4 up to 128 GB, with supported overclocked speeds ranging from 3300 to 4500 MT/s depending on the CPU installed.

How do I confirm the integrated Intel HD Graphics output is active after assembly?

Connect a display to the HDMI 1.4 port; if the system posts at up to 4096×2160@30 Hz with HDCP 2.3, the onboard graphics are working correctly.
