What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

Third-party reviews

What customers like about GIGABYTE X299 UD4

  • High durability with the Ultra Durable (UD) design philosophy and server-class digital power components
  • Excellent value for the X299 platform, often cited as one of the most affordable entry-level boards for LGA 2066 CPUs
  • Strong expansion options with 8 DDR4 DIMM slots for massive memory configurations and 5 PCIe 3.0 slots
  • Dual M.2 slots with thermal guards to prevent SSD throttling during heavy data transfers
  • Reliable redundancy via the GIGABYTE UEFI DualBIOS system to handle potential BIOS corruption

What customers don't like about GIGABYTE X299 UD4

  • Lacks built-in Wi-Fi, requiring users to purchase an additional PCIe or M.2 wireless card
  • BIOS interface can be difficult to navigate and has been described by some users as muddled or containing bugs
  • Limited high-speed PCIe lanes; while there are multiple slots, only two are true x16, which can limit multi-GPU setups
  • Minimalist 'no-frills' aesthetic may not appeal to users looking for flashy RGB lighting or integrated I/O shields
  • Poor software suite; users often report that the RGB Fusion and other utility apps are unstable or difficult to use

Verdict

The Gigabyte X299 UD4 is an ATX motherboard built on the Intel X299 chipset and LGA 2066 socket, designed to support Intel Core X-series processors with high-performance features like quad-channel DDR4 memory across 8 DIMM slots and dual M.2 PCIe Gen3 x4 connectors. Its main characteristics include a server-class digital power design with durable black solid capacitors, high-fidelity Realtek ALC1220 audio, and 3-way graphics support for multi-GPU setups. Key pros are its stable overclocking potential via the Turbo B-Clock tuning IC and extensive customisation through RGB Fusion and Smart Fan 5 thermal management. However, its primary cons include the lack of built-in Wi-Fi and Bluetooth, a relatively minimalist rear I/O with limited USB 3.1 Gen 2 ports, and no support for integrated graphics.
