Verdict

The ASUS ROG Strix X299-E Gaming II is a high-end ATX motherboard designed for Intel Core X-series processors on the LGA 2066 socket and X299 chipset. It features 12 power stages with active VRM cooling, eight DDR4 DIMM slots supporting up to 256GB at 4266MHz+(O.C.), and triple M.2 slots for high-speed NVMe storage. Connectivity is robust with built-in Wi-Fi 6 (802.11ax), 2.5 Gbps and Intel Gigabit LAN, and USB 3.2 Gen 2 ports, including a front-panel Type-C header. Its primary pros include its excellent power delivery for multi-core overclocking, a built-in 1.3-inch LiveDash OLED for system diagnostics, and extensive Aura Sync RGB customization. Main cons involve its high price point compared to standard consumer boards and the requirement of specific 44 or 48-lane CPUs to fully utilize all PCIe and M.2 slot bandwidth.
