Overview
The GIGABYTE Z890 UD is a full-size ATX motherboard built on Intel's Z890 Express Chipset with an LGA1851 socket, engineered to support Intel Core Ultra processors (Series 2). Its 12+1+2 digital twin phase VRM design delivers stable and consistent power delivery for demanding workloads and overclocking sessions, backed by a fully covered MOSFET heatsink featuring a one-piece integrated design with multi-cut channels for improved airflow. Memory support is extensive: four DDR5 DIMM slots accommodate up to 256 GB of system memory (64 GB per DIMM) in dual-channel configuration, with native speeds from 5600 MT/s and overclocked profiles reaching up to DDR5-9200 via XMP. The board also supports CUDIMM and ECC Un-buffered DIMM modules (operating in non-ECC mode), offering broad compatibility for both enthusiast and workstation-adjacent builds. Storage is handled by four M.2 connectors — one PCIe 5.0 x4 slot (M2A_CPU, supporting up to type 25110 drives) and three additional PCIe 4.0 x4 slots — complemented by four SATA 6 Gb/s ports with RAID 0/1/5/10 support for both NVMe and SATA arrays. The primary x16 PCIe 5.0 slot serves the discrete GPU, while two additional chipset-connected PCIe 4.0 x4 slots (in x16 physical form) expand peripheral options. Connectivity on the rear panel includes one USB4 Type-C port (40 Gbps with DisplayPort Alt mode), one USB 3.2 Gen 2 Type-A port, four USB 3.2 Gen 1 Type-A ports, four USB 2.0 ports, a Realtek 2.5GbE LAN port, one DisplayPort 2.1 output (up to 3840×2160@144 Hz), and three audio jacks backed by a Realtek HD Audio CODEC with up to 7.1-channel support. Internal headers include three addressable RGB Gen2 headers, one RGB header, two Thunderbolt add-in card connectors, a Q-Flash Plus button for BIOS updates without a CPU installed, and fan/pump headers compatible with Smart Fan 6 control. The BIOS is AMI UEFI-based with AI Perfdrive for automated performance profiles, Q-Flash, and Q-Flash Plus support.
