Key features
The Intel® LGA 1851 socket paired with the Intel® B860 chipset positions this board to support upcoming Intel® Core™ Ultra processors, delivering accelerated compute performance for AI inference, multitasking and business applications. The chipset optimizes platform stability while supporting the latest feature sets and I/O standards.
Four DDR5 memory slots support blazing transfer rates up to 8666+ MT/s (OC) and up to 256GB total capacity. This memory architecture provides the bandwidth and headroom required for analytics, virtualization, large datasets and multi-application workflows, ensuring responsive performance under sustained loads.
Expand and customize with a PCIe 5.0 x16 SafeSlot for next-gen GPUs or accelerators, a secondary PCIe 4.0 x16 slot (operating at x4 mode) for additional cards, and a PCIe 4.0 x1 slot for networking or I/O add-ins. The board’s integrated graphics support also enables compact builds without discrete GPUs when appropriate.
Dual M.2 slots plus four SATA 6Gb/s ports provide a versatile storage toolkit: NVMe SSDs for ultra-fast system and application storage alongside SATA drives for mass capacity. Built-in SATA RAID 0/1/5/10 support gives you the option to optimize for performance, redundancy or a balance of both in business-critical environments.
Network reliably with an Intel® 1Gb LAN port optimized for stable throughput and management integration. Front and rear USB 3.2 Gen 2 Type-C and Type-A connectors offer fast peripheral and external storage connectivity. Onboard Realtek 7.1 Surround Sound HD audio ensures clear voice communications, multimedia playback and conferencing capability for modern workplace needs. Combined with ASUS Control Center Express, these interfaces simplify device administration and monitoring at scale.
