Prime X299-A II
The Prime X299-A II caters to users with serious pursuit. This high-end desktop board combines cutting-edge performance with our signature features, including an enhanced VRM tailored for running the CPU performance at stock speeds, intuitive cooling control, next-gen connectivity, and extensive customization.
Achieve speed with onboard Triple M.2
Professional applications require fast solid-state storage, which is why the Prime X299-A II is equipped with three M.2 slots that are compatible with the latest NVMe SSDs.
Multi-GPU support
Fully loaded takes on a new meaning when you have over 44 PCI Express lanes stemming from the CPU. Those lanes can be split in an x16/x16/x8 configuration spanning the board's trio of PCIe x16 slots.
Make your DDR4 Memory go faster
The X299 platform delivers ample bandwidth on multiple fronts. Its quad-channel memory controller supports up to 256 GB of DDR4 memory across eight slots which hit memory speeds up to DDR4 4266 MHz or beyond.
AI Overclocking
ASUS AI Overclocking makes automatic tuning faster and smarter than ever before. Available in Windows or directly through the UEFI, it profiles the CPU and cooling to predict the optimal configuration for each individual system.
M.2 Heatsinks
Two M.2 slots are covered by heatsinks to combat temperature-induced throttling that can affect performance during heavy, sustained storage loads.
USB 3.2 Gen 2
Plenty of USB ports are provided to support high-end rigs loaded with peripherals, including a front-panel header with faster USB 3.2 Gen 2 connectivity for compatible cases
Intel Ethernet
The latest Intel I219-V Ethernet has the advantage of reducing CPU overhead and offering exceptionally high TCP and UDP throughput for faster, smoother data transfer.
Intel X299 chipset
The Intel X299 chipset supports LGA 2066-socket Intel Core X-Series Processors. It provides improved performance by utilizing serial point-to-point links. Additionally, X299 provides a maximum 10 USB 3.2 Gen 1 ports, 8 SATA 6 Gbps ports and up to 32 Gbps M.2 support for faster data retrieval.
