Workstation CEB board for Core X-series

The ASUS WS X299 SAGE is an Intel X299 CEB motherboard built for LGA 2066 Core X-series processors. It targets content-creation and compute workloads that benefit from up to four dual-slot graphics cards in 4-way SLI or CrossFireX configurations. Dual Intel gigabit LAN and ASUS Control Center software support managed deployments in small- and medium-business environments.

Verify CPU core count and cooler clearance

Memory capacity depends on the installed CPU: six-core and above models enable all eight DDR4 DIMM slots for up to 128 GB, while four-core models activate only four slots with a 64 GB ceiling. Confirm your chassis can accommodate the CEB form factor and that the chosen cooler clears the metal-fin-array VRM heatsink. The package contains only the motherboard and I/O shield.

Replaces standard X299 ATX boards for multi-GPU

This board upgrades from typical ATX X299 designs when a build requires seven PCIe 3.0 x16 slots wired for quad-GPU operation, dual M.2 sockets plus two U.2 connectors, and 10 Gbps USB 3.1 Gen 2 Type-A and Type-C ports with a front-panel header. The jump is worth it when rendering, simulation or virtualization workloads demand that slot density and storage bandwidth in a single managed platform.

Questions about this item

Which Core X-series CPUs let me use all eight DIMM slots and reach 128 GB?

Six-core and higher Core X-series processors enable all eight slots for a maximum of 128 GB; four-core models are limited to four slots and 64 GB.

Can I run four dual-slot graphics cards on this board?

Yes, the CEB layout provides seven PCIe 3.0 x16 slots that support quad x16/x16/x16/x16 or seven x16/x8/x8/x8/x8/x8/x8 configurations for 4-way SLI or CrossFireX.

What M.2 and U.2 drives fit the onboard connectors?

Two M.2 sockets accept 2242, 2260, 2280 and 22110 lengths, plus two U.2 connectors for 2.5-inch PCIe storage devices.
