Gigabyte X870E Aorus Pro X3D specifications and in-depth review

Gigabyte X870E Aorus Pro X3D

Manufacturer: Gigabyte

The Gigabyte X870E Aorus Pro X3D is an ATX-form-factor motherboard designed around AMD's AM5 platform and the X870 chipset. It supports DDR5 memory across four slots, with a rated maximum capacity of 256GB and overclocked speeds reaching 9000 MHz. The board includes integrated Wi-Fi 7 and Bluetooth 5.4, along with RGB lighting and a dedicated CMOS reset mechanism for straightforward BIOS management.

On the connectivity side, the board offers a well-rounded rear I/O that includes two USB 4 40Gbps ports, two Thunderbolt 4 ports, five USB 3.2 Gen 2 Type-A ports, and two USB 3.2 Gen 2 Type-C ports, alongside a single HDMI 2.1 output and one RJ45 jack. Internal expansion includes four M.2 sockets, four SATA 3 connectors with full RAID 0, 1, 5, and 10 support, one PCIe 5.0 x16 slot, and eight fan headers. Audio is handled through a 7.1-channel solution with a 120 dB signal-to-noise ratio and an S/PDIF output. The board carries a three-year warranty.

Pros
  • Supports Wi-Fi 7, covering all major wireless standards from Wi-Fi 4 through 802.11be
  • Two USB 4 40Gbps ports and two Thunderbolt 4 ports provide high-bandwidth connectivity options on the rear I/O
  • Four M.2 sockets offer ample storage expansion without relying on SATA slots
  • DDR5 memory can be overclocked up to 9000 MHz across four slots with a maximum capacity of 256GB
  • Full RAID support across modes 0, 1, 5, and 10 gives flexibility for storage redundancy and performance setups
  • Eight fan headers allow thorough cooling management across the system
Cons
  • No dual BIOS, meaning there is no hardware-level fallback if the primary BIOS is corrupted
  • ECC memory is not supported, limiting use in error-sensitive workloads
  • Only a single HDMI 2.1 output is available with no DisplayPort, restricting multi-monitor setups from the board itself
  • No USB 2.0 rear ports may cause compatibility issues with older peripherals
  • RAID 0+1 is not supported, narrowing options for certain storage configurations
Who is this for?

This board is well-suited to enthusiast desktop builders targeting the AM5 platform who want to push DDR5 memory with overclocked speeds up to 9000 MHz and take full advantage of a PCIe 5.0 x16 slot for a high-end discrete GPU. The extensive rear I/O — including two USB 4 40Gbps ports and two Thunderbolt 4 ports — makes it a strong fit for users who regularly work with high-bandwidth peripherals or external storage. The four M.2 sockets, broad RAID support, and eight fan headers also make it practical for workstation-oriented setups that demand storage flexibility and thorough thermal management.

Who is this NOT for?

Users who require ECC memory support for error-sensitive or mission-critical computing tasks will find this board unsuitable, as that capability is absent. The single HDMI 2.1 output with no DisplayPort makes it a poor fit for anyone looking to drive multiple monitors directly from the board, particularly those using integrated graphics — which this board does not support at all. Additionally, those who depend on legacy interfaces such as USB 2.0 rear ports, PS/2, or eSATA may find the rear I/O layout incompatible with their existing peripherals.
