MSI X399 Gaming Pro Carbon Ac DDR4 AMD Motherboard

The MSI X399 Gaming Pro Carbon AC is a full-size ATX motherboard engineered for AMD Ryzen Threadripper processors in the SocketTR4 form factor, supporting both 1st and 2nd Generation Threadripper CPUs on the AMD X399 chipset. Designed for high-end desktop (HEDT) builds that demand maximum memory bandwidth and multi-GPU horsepower, it provides a robust foundation for content creation, 3D rendering, and demanding gaming workloads. Memory capacity is a standout feature: eight DDR4 DIMM slots support quad-channel operation and up to 128 GB of RAM, with XMP profiles reaching DDR4-3600 (OC). ECC UDIMM support adds an extra layer of data integrity for professional workloads. The DDR4 Boost design uses a fully isolated and shielded PCB trace layout to maintain signal integrity at high frequencies. Storage is equally capable. Three M.2 Key-M slots — backed by PCIe 3.0 x4 and SATA 6 Gb/s connectivity — are complemented by eight SATA 6 Gb/s ports, with RAID 0, 1, and 10 support via the X399 chipset. Two of the three M.2 slots accept up to 2280 drives, while the third accepts the extended 22110 (110 mm) form factor for enterprise-grade NVMe SSDs. Expansion slots include two PCIe 3.0 x16 and two PCIe 3.0 x8 slots protected by Steel Armor reinforcement, enabling 4-Way NVIDIA SLI and 4-Way AMD CrossFire multi-GPU configurations. Connectivity is handled by an Intel I211 Gigabit LAN controller and an Intel Dual Band Wireless-AC 8265 card offering 802.11 a/b/g/n/ac on 2.4 GHz and 5 GHz bands at up to 867 Mbps, alongside Bluetooth 4.2. USB throughput is extensive: two USB 3.1 Gen2 ports (one Type-A, one Type-C) on the rear panel via ASMedia ASM3142, eight USB 3.1 Gen1 Type-A ports from the CPU, and additional internal headers. Audio is driven by a Realtek ALC1220 codec delivering 7.1-channel HD audio with S/PDIF optical output and gold-plated connectors. Mystic Light RGB illumination offers 16.8 million colours across 17 effects, controllable via MSI's software, with two onboard RGB LED headers for strip synchronisation. A dedicated water pump header and four system fan headers round out the thermal management options. The Flash BIOS button allows firmware recovery without a CPU or memory installed.
