Gigabyte B860M Aorus Elite specifications and in-depth review

Gigabyte B860M Aorus Elite

Manufacturer: Gigabyte

The Gigabyte B860M Aorus Elite is a Micro-ATX motherboard designed around Intel's LGA 1851 platform and the B860 chipset. It measures 244 mm × 244 mm and includes RGB lighting alongside a dual BIOS feature, giving users a backup firmware option should the primary BIOS encounter an issue. The board ships with a three-year warranty and supports easy overclocking through its BIOS configuration.

On the memory side, the board accommodates up to 256 GB of DDR5 RAM across four slots in a dual-channel configuration, with standard speeds reaching 6400 MHz and overclocked profiles going as high as 9200 MHz. Expansion is handled by a single PCIe 5.0 x16 slot and a PCIe x4 slot, while storage options include three M.2 sockets, four SATA 3 connectors, and full support for RAID 0, 1, 5, and 10. The rear I/O provides a Thunderbolt 4 port alongside a USB 4 40 Gbps connection, HDMI 2.1, one DisplayPort output, and a 7.1-channel audio solution with S/PDIF output.

Pros
  • Supports DDR5 memory with overclocked speeds up to 9200 MHz across four slots, with a maximum capacity of 256 GB
  • Dual BIOS provides a firmware backup, reducing the risk of a failed update leaving the board unbootable
  • Includes a Thunderbolt 4 port and a USB 4 40Gbps connection on the rear I/O, enabling high-bandwidth peripheral and display options
  • Three M.2 sockets alongside four SATA 3 connectors offer flexible storage configuration with support for RAID 0, 1, 5, and 10
  • A PCIe 5.0 x16 slot ensures compatibility with the latest generation of discrete graphics cards and other high-bandwidth expansion cards
  • Six fan headers give users meaningful control over system cooling across the board
Cons
  • No built-in Wi-Fi or Bluetooth, requiring separate adapters for wireless connectivity
  • Clear CMOS functionality is not supported, making manual BIOS recovery less straightforward
  • Only one PCIe x4 slot available beyond the primary x16 slot, limiting multi-card or high-speed expansion options
  • No USB-C ports on the rear I/O despite having a USB-C header for front-panel use, which may inconvenience users who rely on rear Type-C connections
  • ECC memory is not supported, ruling out error-correcting RAM configurations for workstation or reliability-sensitive use
Who is this for?

This board is a solid fit for users building a capable desktop system on the LGA 1851 platform within a compact Micro-ATX footprint. Those who want to push memory performance will appreciate the DDR5 support with overclocked speeds reaching 9200 MHz, and builders who prioritize storage flexibility will benefit from the three M.2 sockets, four SATA 3 connectors, and broad RAID support. The Thunderbolt 4 and USB 4 40Gbps rear connectivity makes it well suited for users working with high-speed external storage or displays, while the PCIe 5.0 x16 slot accommodates the latest discrete graphics hardware without compromise.

Who is this NOT for?

Users who depend on wireless connectivity out of the box will find this board lacking, as neither Wi-Fi nor Bluetooth is built in, requiring additional hardware to achieve either. It is also a poor match for workstation or server-oriented builds that rely on ECC memory for error correction, as that capability is absent. Additionally, builders who need multiple high-speed expansion slots — such as those running several NVMe cards via PCIe adapters or multi-GPU configurations — will be constrained by the board's single PCIe 5.0 x16 slot and single PCIe x4 slot.
