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.

What customers like about GIGABYTE B660M Gaming DDR4

  • Highly affordable entry-level B660 motherboard
  • Supports PCIe 4.0 for GPUs and NVMe SSDs
  • Dual M.2 slots for high-speed storage expandability
  • Effective 2.5GbE LAN for stable gaming connectivity
  • Simple, clean aesthetic suitable for most builds
  • Reliable performance when paired with i3 or lower-end i5 CPUs
  • Features 'Smart Fan 6' for customizable cooling control

What customers don't like about GIGABYTE B660M Gaming DDR4

  • Weak VRM design limits usage with high-power i7 or i9 CPUs
  • Lack of VRM heatsinks can lead to thermal throttling under heavy loads
  • Only two DIMM slots (supports up to 64GB, not 128GB)
  • Limited rear I/O with few USB ports compared to higher-end models
  • Basic audio codec (Realtek ALC897) may lack premium sound quality
  • Initial BIOS versions reported to have odd power-limit behaviors
  • No integrated Wi-Fi (requires separate adapter or higher 'AC' model)

Verdict

The Gigabyte B660M Gaming DDR4 is a budget-friendly Micro-ATX motherboard designed for 12th, 13th, and 14th Gen Intel Core processors on the LGA 1700 socket. It features a 6+2+1 phase hybrid digital VRM with MOS heatsinks, two DIMM slots supporting dual-channel DDR4 memory up to 5333MHz (O.C.), and dual PCIe 4.0 x4 M.2 slots for high-speed storage. Key characteristics include a fast 2.5GbE LAN with bandwidth management, rear USB 3.2 Gen 1 Type-C connectivity, and RGB Fusion 2.0 support. Its main pros are the inclusion of Q-Flash Plus for BIOS updates without a CPU, robust cooling via Smart Fan 6, and high-quality audio capacitors with a noise guard. However, notable cons include its limited expansion capability with only two RAM slots and a lack of integrated Wi-Fi on the base model.
