Verdict

The ASRock B660M-HDV is an entry-level Micro ATX motherboard designed for 12th, 13th, and 14th Gen Intel Core processors on the LGA1700 socket, featuring a 6-phase power design and two DDR4 DIMM slots supporting dual-channel memory up to 5066+(OC) MHz. Its main characteristics include triple graphics outputs (HDMI, DisplayPort, and D-Sub), Intel Gigabit LAN, and dual M.2 storage options with one Hyper M.2 slot supporting PCIe Gen4 x4 speeds. Pros include its highly affordable price point, front-panel USB 3.2 Gen1 Type-C header, and a dedicated M.2 Key-E slot for adding a WiFi module. However, notable cons include a lack of VRM heatsinks which leads to thermal throttling on high-power CPUs (like the i7 or i9), a limited two-slot RAM configuration, and the absence of modern high-speed 10Gbps USB ports or diagnostic troubleshooting LEDs.

What customers like about ASRock B660M HDV?

  • Very budget-friendly pricing, often the cheapest B660 option available
  • Includes essential modern features like two M.2 SSD slots (one Gen4, one Gen3)
  • Provides a dedicated M.2 Key-E slot for easy Wi-Fi card integration
  • Supports full RAM overclocking, which is a significant upgrade over H610 chipset boards
  • Compact micro-ATX form factor makes it ideal for small-budget builds
  • Capable of handling entry-level to mid-range CPUs like the i3-12100F and i5-12400F without issues

What customers dislike about ASRock B660M HDV?

  • Extremely weak VRM (Voltage Regulator Module) with no heatsinks, leading to high temperatures
  • Severe thermal throttling when used with high-power CPUs (i7 or i9), preventing them from reaching advertised clock speeds
  • Lack of 'relevant' I/O such as high-speed 10Gbps USB ports and front-panel Type-C headers
  • Limited to only 2 RAM slots and 1Gbps Ethernet
  • Enforces strict power limits (e.g., 95W PL1) that can bottleneck performance even with adequate cooling
  • No RGB or ARGB headers, which may be a downside for users wanting aesthetics
