GIGABYTE Z490 UD DDR4 Intel Motherboard

The Gigabyte Z490 UD is an ATX form-factor motherboard built on the Intel Z490 Express Chipset, designed for the LGA1200 socket and compatible with 10th Generation Intel Core i9, i7, i5, i3, Pentium, and Celeron processors. It measures 30.5 cm x 24.4 cm and fits standard ATX chassis. Power delivery is handled by a direct 11+1 phase digital VRM with low RDS MOSFETs, paired with an enlarged VRM heatsink featuring air-flow grooving for improved thermal performance under sustained CPU loads. Memory support spans four DDR4 DIMM slots in a dual-channel configuration, accommodating up to 128 GB (using 32 GB single-DIMM modules). Core i9 and i7 processors can leverage XMP profiles up to DDR4-4500 (O.C.), while i5, i3, Pentium, and Celeron processors run at DDR4-2666/2400/2133 MHz natively. Intel Optane Memory is also supported. Storage options include two M.2 Socket 3 connectors — one supporting both SATA and PCIe x4/x2 in sizes up to 22110, and a second supporting PCIe x4/x2 in sizes up to 2280 — alongside six SATA 6 Gb/s ports with RAID 0/1/5/10 support. Connectivity is handled by a Realtek GbE LAN chip (1 Gbps / 100 Mbps) with the Realtek 8118 bandwidth management utility included. On the rear I/O, users have one USB 3.2 Gen 2 Type-A port (10 Gbps), five USB 3.2 Gen 1 ports, two USB 2.0/1.1 ports, one HDMI 1.4 output (up to 4096×2160 @ 30 Hz), one PS/2 port, one RJ-45, and three audio jacks. Audio is powered by a Realtek ALC887 codec supporting up to 7.1-channel output with S/PDIF Out. Expansion consists of one PCIe x16 slot at full x16 bandwidth, one PCIe x16 physical slot running at x4, and three PCIe x1 slots — all conforming to PCIe 3.0. AMD Quad-GPU CrossFire and 2-Way CrossFire configurations are supported. Two Thunderbolt add-in-card connectors are present for optional Thunderbolt 3 expansion. RGB Fusion 2.0 controls onboard lighting as well as external LED strips via two addressable (5 V) and two standard RGB (12 V) headers, supporting up to 300 individual LEDs. Smart Fan 5 provides hybrid fan control with FAN STOP capability across one CPU and four system fan headers. The Q-Flash Plus button enables BIOS updates without installing a CPU, memory, or GPU. The board carries a 3-year warranty.
