GIGABYTE Z790 D DDR5 Intel Motherboard

The GIGABYTE Z790 D DDR5 is an ATX form-factor motherboard (305 mm × 244 mm) built on the Intel Z790 Express Chipset and designed for the LGA1700 socket. It supports Intel Core, Pentium Gold, and Celeron processors from the 12th, 13th, and 14th generations, making it a versatile foundation for a wide range of Intel-platform builds. Memory flexibility is a standout aspect of this board. Four DDR5 DIMM sockets operate in dual-channel configuration and accept up to 192 GB of system memory using 48 GB single-DIMM modules. With compatible 13th and 14th Generation Core i9 and i7 processors, memory speeds can reach DDR5-7600 MT/s in overclocked mode, with a broad ladder of validated speeds including DDR5-5600 and below as native-rated options. XMP profile support is included, and ECC Un-buffered DIMMs (operating in non-ECC mode) are also accommodated. GIGABYTE’s shielded memory routing, impedance-optimised PCB topology, and low-loss PCB material are engineering features cited in the source specification that collectively aim to maintain signal integrity at high DDR5 data rates. Expansion and storage are well provisioned. The primary PCIe x16 slot runs at PCIe 5.0 x16 and features GIGABYTE’s EZ-Latch quick-release mechanism. Additional chipset-connected slots include a PCIe 4.0 x16 physical slot (electrical x4) and three PCIe 3.0 slots. Storage options comprise three M.2 connectors (all PCIe 4.0 x4 capable, with one also supporting SATA) and four SATA 6 Gb/s ports. RAID 0, 1, 5, and 10 configurations are supported for both NVMe and SATA arrays. Connectivity on the rear I/O panel includes one USB Type-C port (USB 3.2 Gen 2, 10 Gb/s), one USB 3.2 Gen 2 Type-A port, four USB 3.2 Gen 1 Type-A ports, two USB 2.0 ports, HDMI 2.1 (up to 4096×2160 @ 60 Hz), DisplayPort 1.2 (up to 4096×2304 @ 60 Hz), and a Realtek 2.5GbE RJ-45 jack. Audio is delivered via a Realtek High Definition Audio CODEC supporting up to 7.1-channel output with S/PDIF out. Power delivery is handled by a 12+1+1 phase digital VRM using an AMI UEFI BIOS stored on a 256 Mbit flash chip. Thermal management includes an enlarged single-piece MOSFET heatsink and M.2 thermal guards. The Smart Fan 6 system supports multiple temperature sensors, hybrid fan headers, and FAN STOP functionality. Q-Flash Plus allows BIOS updates without a CPU, memory, or GPU installed.
