ASUS ROG Rampage VI Extreme Encore LGA 2066

The ASUS ROG Rampage VI Extreme Encore is an ATX motherboard built for the Intel X299 chipset and LGA 2066 socket. It targets enthusiasts assembling high-end desktop systems that demand extensive connectivity and robust power delivery. The board provides a foundation for multi-core processors and high-bandwidth add-in cards.

DDR4 256GB maximum memory capacity

Four DDR4 slots support up to 256GB of system memory, giving ample headroom for memory-intensive workloads such as video editing, 3D rendering and virtualisation. Populating all slots with high-capacity modules reaches the chipset limit, beyond which the platform cannot address additional RAM. Typical consumer kits well below this ceiling run without configuration issues.

Bundled SATA cable and I/O shield

The package includes one SATA cable and the chassis I/O back panel, covering basic storage and rear-port installation needs. No additional cables, Wi-Fi antennas or RGB accessories are supplied, so builders must source extra SATA leads, fan headers or mounting hardware separately. The metal battery is fitted on the board.

Questions about this item

Will my existing DDR4 memory kits work with the 256GB maximum supported by this X299 board?

Yes, the motherboard supports DDR4 up to a total capacity of 256GB, so any compatible DDR4 modules you already own can be used within that limit.

How can I confirm the LGA 2066 socket and X299 chipset are functioning correctly after installation?

Enter the BIOS on first boot; the POST screen will display the detected CPU socket type and chipset identifier, confirming the board recognises the hardware.

Does the package include the I/O shield and a SATA cable, or must I source them separately?

The box contains the motherboard, one SATA cable, and the chassis I/O back panel, so no additional accessories are required for basic installation.
