GIGABYTE X399 Aorus Pro DDR4 AMD Motherboard

The Gigabyte X399 Aorus Pro DDR4 is an ATX-form-factor enthusiast motherboard built on the AMD X399 chipset, designed for AMD Ryzen Threadripper processors in the SocketTR4 package. Measuring 30.5 cm x 24.4 cm, it fits standard ATX chassis and targets workstation-class workloads such as rendering, video encoding, streaming, and content creation. Memory support is a standout feature: eight DDR4 DIMM slots accommodate up to 128 GB of system RAM in a quad-channel configuration. Supported speeds range from 2133 MHz up to 3600+ MHz (OC), with native XMP compatibility. The board also accepts ECC Unbuffered DIMM modules (1Rx8/2Rx8), making it suitable for professionals who require error-correcting memory. Storage is covered by three M.2 Socket 3 connectors — two supporting 2260/2280/22110 form factors and one supporting 2242/2260/2280 — all capable of both SATA and PCIe x4/x2 NVMe SSDs. Eight SATA 6 Gb/s ports add further capacity, and the platform supports NVMe RAID 0, 1, and 10 arrays at no extra cost. Expansion flexibility is broad: two PCIe 3.0 x16 slots, two PCIe 3.0 x16 slots running at x8, and one PCIe 2.0 x16 slot running at x4 enable up to 4-Way AMD CrossFire or 4-Way NVIDIA SLI configurations. Networking is handled by an Intel Gigabit Ethernet controller paired with cFosSpeed traffic-management software. USB connectivity on the rear panel includes eight USB 3.1 Gen 1 ports, one USB 3.1 Gen 2 Type-A port, and one USB 3.1 Gen 2 Type-C port. Audio is delivered through a Realtek ALC1220 codec rated at up to 120 dB SNR, supporting 2/4/5.1/7.1-channel output and S/PDIF Out. A Smart Headphone Amp automatically adjusts output to match headphone impedance. RGB Fusion 2.0 manages onboard lighting and supports both 5 V addressable and 12 V RGB LED strip headers. The Smart Fan 5 system provides six hybrid fan/pump headers, water-cooling flow-rate monitoring, and per-fan curve customisation. Dual AMI UEFI BIOS chips (DualBIOS) protect against firmware corruption. The board ships with a 3-year manufacturer warranty.
