Socket LGA 2066 ATX Motherboard

This ASUS ROG Rampage VI Extreme Encore motherboard uses the Intel X299 chipset and an LGA 2066 socket. It is built for Intel Core X-Series 10000 processors and supports DDR4 memory up to 256GB across eight DIMM slots. The board targets enthusiasts and workstation users who need high core counts and extensive connectivity.

Enthusiasts seeking maximum I/O and memory capacity

The board suits builders who need three PCIe 3.0 x16 slots with flexible lane configurations, a ROG DIMM.2 module for additional M.2 storage, and a 10G Aquantia AQC-107 LAN port alongside Intel I219V. It also provides extensive USB connectivity including a front-panel USB 3.2 Gen 2x2 20Gbps port. Users with mainstream CPUs or smaller budgets should consider a different platform.

Verify CPU, memory, cooler and case compatibility

Confirm your processor is an Intel Core X-Series 10000 family CPU that fits LGA 2066. Ensure DDR4 modules match the supported overclocked speeds up to 4266 and that total capacity does not exceed 256GB. Check that your CPU cooler mounting matches the socket and that your ATX case accommodates the board dimensions of 30.5 by 27.7.

Questions about this item

What CPU socket and chipset must my processor match for this board?

The board uses an LGA 2066 socket and Intel X299 chipset, so the processor must be a Core X-Series 10000 family CPU.

Will my existing PCIe 3.0 add-in cards work in the three x16 slots?

Yes — the board provides three PCIe 3.0 x16 slots that operate in x16/x16/x4, x16/x8/x8 or x16/x8/x4 modes depending on the CPU installed.

How can I confirm the 10 GbE and USB 3.2 Gen 2x2 ports are active after build?

Check Device Manager for the Aquantia AQC-107 10G adapter and a 20 Gbps USB controller, then run a network throughput test and a USB 3.2 Gen 2x2 device benchmark.
