ASUS Prime X299-A II ATX Motherboard | LGA2066 | 8x DDR4 Slots
Description
The ASUS Prime X299-A II brings Intel's high-end X299 platform to ATX form factor, built around the LGA2066 socket for Intel Core X-series processors. This is a serious enthusiast platform designed for content creators, workstation users, and power users who need the multi-core performance and expanded memory capacity that only the X299 chipset can deliver. With support for up to 256GB of DDR4 memory across eight DIMM slots, it offers the kind of memory expandability that mainstream platforms simply can't match.
The board supports DDR4 speeds from 2133MHz up to 4266MHz with compatible modules, giving you flexibility to balance performance and budget. Three M.2 slots provide ample storage expansion options, while eight SATA ports ensure plenty of room for traditional drives. The dual PCIe x16 slots handle multi-GPU setups, and two additional PCIe x1 slots add room for expansion cards. Gigabit Ethernet and Realtek S1220A audio codec handle networking and sound duties.
ASUS includes essential accessories in the box: an I/O shield, SATA cables for storage connections, M.2 mounting hardware, and a comprehensive user guide to help with setup. The board supports XMP memory profiles for easy overclocking of compatible DDR4 modules. While the X299 platform targets users with specific high-performance needs rather than general gaming builds, it delivers the processing power and memory capacity that demanding applications require.
